波动性有一种不请自来的方式。
有一天,澳大利亚证券交易所正在悄然波动... 第二天,保证金要求上升,止损未达到预期,投资组合开盘时出现令人不安的隔夜缺口。
如果您一直在寻找答案,那么您并不孤单。澳大利亚交易者中一些最常搜索的有关波动性的问题与追加保证金、滑点、隔夜缺口、杠杆交易所交易基金(ETF)以及平均真实区间(ATR)等工具有关。
以下是正在发生的事情。
为什么现在这很重要
全球市场对利率、通货膨胀数据、地缘政治和技术驱动的流动变得更加敏感。当流动性减少和不确定性增加时,价格波动就会扩大。那就是波动性。
波动性不仅会影响价格方向,还会改变交易的执行方式、需要多少资本以及表面之下的风险表现。
翻译:波动性不仅仅是更大的波动,而是更快的走势和更少的流动性——那是交易机制最重要的时候。
想要真实世界的波动率案例研究吗?
为什么我的经纪人提高了保证金要求?
关于波动率的搜索最多的问题之一是为什么保证金要求在没有警告的情况下增加。
当市场变得不稳定时,经纪商可能会提高差价合约(CFD)和其他杠杆产品的保证金要求。较大的价格波动会增加账户转为负资产的风险,因此提高保证金要求会降低可用杠杆率,并有助于在极端条件下管理风险敞口。
这在实践中可能意味着什么
-即使价格没有显著变动,也可能会出现追加保证金的情况。
-有效杠杆率可能会迅速下降。
-可能需要在短时间内减少职位。
保证金调整通常是对不断变化的市场风险的回应,而不是随机决定。在高度波动的市场中,谨慎的做法是假设保证金设置可以迅速变化,因此,许多交易者选择根据这种风险来审查头寸规模和可用缓冲区。
什么是滑点?为什么我的止损没有按我的价格成交?
另一个经常搜索的话题是滑点。
当止损单触发并以下一个可用价格执行时,可能会发生滑点,结果可能取决于订单类型、市场流动性和缺口。在平静的市场中,差异可能很小,而在快速市场中,价格可能会跳出止损水平。

常见的驱动程序包括
-主要经济或财报发布。
-流动性薄弱。
-拥挤的停车位。
-通宵会议。
止损订单通常优先执行而不是价格确定性,在高波动时期,这种区别变得很重要。根据典型的价格走势调整头寸规模和设置止损可能比在不稳定条件下简单地收紧止损更有效。
如何管理澳大利亚证券交易所的隔夜差距?
澳大利亚在美国沉睡的时候进行贸易,反之亦然。遗憾的是,这种时区差异是澳大利亚交易者经常寻找隔夜缺口风险的原因之一。如果美国市场大幅下跌,澳大利亚证券交易所可能会在第二天早上开盘走低,在收盘和开盘之间没有机会退出。
市场交易者可能使用的风险管理方法的示例包括
-使用澳大利亚证券交易所200指数期货或差价合约*进行指数套期保值。
-在高风险事件期间进行部分对冲。
-在重大宏观公告发布之前减少风险敞口。
套期保值可以抵消部分走势,但会带来基础风险,因为个别股票的走势可能与整体指数不一致。
没有完美的保护,只有在成本、复杂性和风险降低之间进行权衡。
*差价合约是复杂的工具,由于杠杆作用,存在很高的亏损风险。
在波动的市场中,杠杆或反向ETF的主要风险是什么?
在波动性加剧的时期,通常会搜索杠杆和反向ETF。
虽然这些产品通常每天重置,但它们的目标是提供该指数每日回报的倍数,而不是其长期回报。在波动的横盘行情中,即使指数收盘价接近起始水平,每日复利也可能侵蚀价值。

之所以发生这种情况,是因为收益和损失不对称地复合。下降10%需要超过10%的收益才能恢复。当这种影响每天成倍增长时,随着时间的推移,结果可能会与基础指数出现重大差异。
一些市场参与者可能会在战术上使用此类工具。它们通常不是作为长期对冲工具设计的,在将它们用于策略之前,了解它们的结构至关重要。
如何使用 ATR 为止损位置提供信息?
平均真实波动范围(ATR)是衡量波动率的常用指标。
ATR 估算资产在给定时期内通常会有多少波动,包括缺口。一些交易者没有将止损设置为任意百分比,而是参考ATR并将止损设置为倍数,例如ATR的两到三倍,以反映当前情况。
当波动率上升时,ATR 会扩大,如果要保持总体风险不变,这可能意味着更大的止损或更小的头寸规模。这种转变不是问:“我愿意输多远?”改为问:“在当前条件下,正常的举动是什么?”
波动市场中的实际注意事项
在波动性加剧的时期,交易者可以考虑
- 考虑到保证金变动的可能性
- 如果波动率增加,则保守地调整头寸
- 认识到止损单并不能保证特定的退出价格
- 在重大经济事件发生之前审查风险敞口
- 了解杠杆ETF的每日重置机制
- 使用诸如ATR之类的波动率指标来为止损设置提供信息
- 保持足够的现金缓冲区
波动率并不能仅奖励预测。准备和风险意识可以帮助交易者了解潜在的风险,但结果仍然不可预测。

这对澳大利亚交易者意味着什么
与亚洲和美国市场相比,澳大利亚市场面临着特定的结构性考虑。隔夜缺口风险受美国交易时间的影响,澳大利亚证券交易所等资源密集型指数可以快速应对大宗商品价格走势和来自中国的数据。货币敞口,包括澳元和美元(USD)的走势,可能会增加另一层波动性。
各地区的波动性并不均匀。根据市场结构和流动性深度,它的行为会有所不同。
有关波动率的常见问题
是什么原因导致市场波动突然飙升?
利率决定、通货膨胀数据、地缘政治发展、盈利意外和流动性限制是常见的触发因素。
为什么经纪人在动荡的市场中增加利润?
减少杠杆风险敞口并在价格波动扩大时管理风险。
在波动期间,止损订单会失败吗?
如果市场跳空超过止损水平,他们可能会出现下滑,这意味着执行的价格可能低于预期。在快速或流动性不足的市场中,这种差异可能很大。
杠杆ETF适合长期对冲吗?
由于每日重置,它们通常是针对短期风险敞口而设计的。它们是否合适取决于您的目标、财务状况和风险承受能力。
在进行交易之前如何衡量波动率?
ATR、隐含波动率指标和历史区间分析等工具可以帮助量化当前状况。
风险警告:波动加剧的时期可能导致价格快速变动、利润率变化以及以不同于预期的价格执行。止损订单和波动率指标等风险管理工具可能有助于评估市场状况,但不能消除损失风险,尤其是在使用杠杆产品时。


How to use Arbitrage trading to increase profits Professionals in finance like to use hard to read and complicated language to make what they do much harder and more complicated than it sounds. However, when it comes to arbitrage, it is actually a relatively simple concept that can be used in trading, to develop an accurate system that can be used in various markets. The Law of One Price In order to understand Arbitrage trading, a trader needs to understand the law of one price.
It states that the same goods sold in different markets in conditions, free of competition and expressed in the same currency, must be sold at the same price. Although this is an economic theory, the principles follow into financial markets. This means that in an efficient market, prices for the same asset cannot be different.
In practice, this is not always the case or rather it is not always the case straight away and his is where arbitrage opportunities exist as the market tries to move the prices into one. What is an Arbitrage? An arbitrage is when the law of one price has not yet been realized.
Essentially, the market is in the process of converging the prices. The best example is that of dual listed companies. These are companies who have shares listed on multiple exchanges.
Initially the price may be different due to exchange rates, different number of shares on issue. However, the relative value for each share must be the same. Usually, they are larger companies or multinational companies.
For instance, BHP is listed on both the ASX and the London Stock Exchange. The strategy can involve selling the shares on the exchange where it is more expensive and buying them back on the cheaper exchange or the alternative and profiting the difference. Other arbitrage opportunities can exist in companies that are primarily traded on an exchange but also have an over the counter, (OTC) listing.
These OTC listings are often much more illiquid allowing for more arbitrage opportunities Additionally, the primary market will usually be the lead pricing target, whilst the OTC or secondary market will attempt to move towards that price. Merged Arbitrage This strategy involved targeting companies that are in the process of being taken over or bought out. The acquirer will need to put an offer per share in order for a take-over to occur.
This gives the market a value for the shares. Generally speaking, the price will have to move towards the offer, especially if it is accepted. In a recent example, company Tassal formally TGR.AX, announced it was being bought out by a private equity firm.
There were previous offers made at $4.67, $4.80 and $4.85 per share before the final offer came at $5.25 a share. It can be seen from the price chart that the share price did not reach $5.25 immediately. The interesting thing to note here is that even though the final and accepted offer came in at $5.25 on the day of the announcement the price only reached $5.12 still $0.13 short of the offer.
This represented an arbitrage opportunity of $0.13 for savvy traders and investors. Although the actual % gain was not very high, the relative certainty of the price target made this trade a potential big winner. Opportunities like this are not always perfect and deals may not always follow through, but a skilled trader can develop a very strong system around this premise.
Overall, arbitrage trading may seem difficult but in reality, the theory is relatively straight forward. Finding mispricing within the market and capitalising on them can take some practice but they can also offer longer and shorter terms edges when the market is not providing other sufficient trading opportunities.


As a new trader, riding the emotional ups and downs can be a very difficult task. It is human nature to feel the pain of a losing trade. The losing often outweighs the positive feeling of any winning trade.
Dealing with the emotion of trading can be an incredibly difficult task. It can cause even the best system to fail. A trading journal especially early on in a trading journey can provide important feedback and information about the effectiveness of an edge.
The reality is that early on profit and loss can be terrible measure of an individual’s trading ability which is why a journal is so essential. There are many different formats and styles of journals that can be used. Some like to base their journal around a calendar.
Others like to pick out their best and worst trade each day and analyse them intensely. In the end, it doesn’t matter what style is chosen if a consistent structure is followed. Both quantitative and qualitative measures that ca be used to measure performance.
What to include in your journal? Below is a breakdown of elements that can be analysed in the trading journal. Initial trade idea – This is the overall basis of the trade, it can be related to a technical pattern, fundamental factor such as a news or a mix of both.
Some traders call this the trade hypothesis or thesis. In its most simple form, it is the very reason a trader enters into a trade. When journaling, it is important to evaluate the strength of the idea, whether it was correct and why or why not the trade was validated or invalidated.
It is also worth noting if the idea is a common one, such as news catalysts, repeating technical patterns. This can also be elevated by understanding how different trade ideas work together to create stronger overall trade ideas. Entry – Breaking down the key elements of the trade are important aspects to a journal.
More specifically outlining whether an entry was ideal, correct and managed well. Was the entry chased or was patience shown to achieve a more ideal entry. The entry is also a part of a trade with heightened emotion.
Therefore, journaling how emotions were managed and ways to improve emotional management is an important aspect of reviewing the entry. Exit – It goes without saying that the exit is the reciprocal of the entry and just as important. Analysing whether the exit was correct at both the time and in hindsight is an important step.
By continuously analysing both entries and exits, a trader will likely see an improvement in this aspect of their trading. In addition, they will potentially remove external factors such as emotion and noise from other influences such as twitter. Sizing – Sizing is an extremely tricky area of trading to master and there are many different theories on what sizing tactic is the best for each trade.
Some traders like to increase size depending on how strong a trade set up is whilst other like to have more consistent sizing strategies regardless of the strength of a trade. When reviewing it is important to make note of whether the sizing strategy worked. Trading with too much size can affect the active management of a trade as a trader can lose sight of the trade at hand and become too concerned about the potential outsizes loss.
Trade management – Whilst all the above can all constitute some level of trade management reviewing, analysing the whole management of the trade is vital. This can include the effectiveness in taking profits or losses and how the trader has dealt with their emotions. Management of fear and greed are the two most common emotions that a trader feels.
Grading – Having some quantitative measure even though it is subjective can help classify many trades over a long period of time. Using either letters or a number ranking can be just one method. This allows for a trader to identify their best performing trades and where the strongest edge is.
This list should not be seen as exhaustive, and traders can tinker and adjust to suit their own trading strategy. Reviewing the journal. It is important to review the journal at the end of a set time whether it be weekly or monthly to see if common mistakes are occurring or a theme is emerging.
If the same mistake keeps occurring, it may act as point of emphasis for future journaling or improvement. Ultimately, using a journal can accelerate the learning curve drastically especially for new traders.


The market in recent months has created exceptionally difficult conditions to trade. Low volatility and obscure price action has reduced the volatility available for traders to capitalise on. These conditions have affected FOREX, Equity, and Index trading.
It has been specifically difficult for momentum and trend following traders as a certain level of volatility is needed for trader to return profitable trades. How to spot low volatility The Average True range or ATR range can be an important indicator in determining the level of volatility in a market or asset. It measures the average trading range of a particular asset’s price over a period.
It can exceptionally be helpful in determining how volatile the asset is at a certain point in time, or how volatile an asset is compared to another one. For instance, looking at the ATR for the Dow Jones, it has been getting progressively lower and is at its lowest level since August indicating a reduction in volatility. The Market Volatility Index or the VIX measures volatility across the S&P 500 is also an important indicator to not just gauge market volatility, but also general market sentiment and emotion.
When fear and greed are prominent in the market volatility tends to increase and when they dissipate, they tend to decrease. As the chart shows, volatility has been reducing to levels not seen since the rally in August 2022. The characteristics of the chart are also interesting as the VIX acts much more in waves then other indices do.
How can you optimise your trading during periods of low volatility? Tips for trading in low volatility markets Understand that breakouts will fail. Specifically for traders who like to use strategies based on momentum breakouts, during times of low volatility the price means to stay close to moving averages and mean price points both on an intra and inter day level.
Wait for confirmation before a momentum move. Although breakouts are less common in low volatility markets, they do still occur. In this instance, it is ideal to wait for a confirmation or retest of an important level before entering trades.
Confirmation can be supported by strong candle in support or increased volume. Being patient is essentially in times of low volatility. Opportunities that may have otherwise eventuated.
Utilising volume and strong candlesticks as secondary Price tends to stay close its mean. This means that if a price does break out or break down, the price often swings back to the mean. The mean may be a simple moving average, Volume Weighted Average, or some other measure.
In essence it does not really matter what is used, rather than the price tends to retrace back to the mean in some manner. Therefore, these conditions lend themselves to mean reversion systems or strategies. As seen on the chart below, the price has reverted to the 20-period moving average on multiple occasions.
Using multiple time frame analysis for identifying support and resistance. As previously stated, when there is low volatility, finding real breakouts that will last becomes more difficult. By ensuring that the breakouts or breakdowns in price are occurring across multiple timeframes a trader can enhance their chance of it being sustained as their will likely be a higher level being traded at longer term levels.
Trading can be difficult during periods of low volatility. However, this does not mean traders should not trade. Rather, traders should be aware of potential obstacles and difficulties that may arise and the strategies that can help work though these difficulties.


Stop loss hunting is frustrating, annoying and can be detrimental to any retail trader. The premise of stop hunting is that large systemised institutional trading strategies know where the average retail trader or most traders will set stop losses and therefore profit off triggering these ‘stops. Their own algorithm will then deliberately, trigger the stop losses.
For traders there are few things as frustrating as have a well-positioned trade, being stopped out and then watching the price reverse in their original direction of the trade. What is a stop loss? Understanding stop loss hunting requires a simple understanding of what a stop loss is.
A stop loss is a trigger on traders’ position to close the position at a certain price. Generally, once triggered the position will attempt to be closed at the specified price. Stop losses provide an important role in risk management for many traders.
Generally, traders use stops losses to avoid emotional mismanagement and better manage overall risk by having clear exit points for the trade in worst case scenarios. The second element that is important to understand is where traders put their stop losses and why. Retail traders often place their stop losses near important market structures also known as support and resistance levels.
These areas represent strong zones of supply and demand. When support and resistance zones become more and more consistent and more obvious, it can create a clump of stop losses. These stop losses can be thought of as orders that must get filled if the price reaches those points.
This creates an attractive opportunity for large institutions with powerful algorithms that can push the price down and generate profits by ‘stopping out’ traders by triggering these stop losses. Once this process has occurred, the price will often move back in the direction the original trades were positioned for. Why would a system want to trigger stop losses Firstly, when stop losses are triggered, a price tends to see an increase in relative volatility.
Therefore, it may indicate the beginning of a reversal which sophisticated traders profiting. It also allows these large institutions to maximise their own existing trades as it may allow for better entries. Common areas for where stop hunters will look Stop Loss hunting tends to be most active around significant and clear areas of support and resistance.
This is especially true with regards to commonly traded assets. However, stop loss hunting can occur in all assets with various sizes. A stop hunt can be seen often with a small candlestick and a large wick.
In addition, they often occur on very short time frames. Common Area for Stop Loss Hunting At key moving average levels Clear Support and Resistance Levels Historical Support and Resistance Levels ie, Multiyear levels How to deal with Stop Loss Hunting? The obvious tactic to deal with stop hunting is to lower the stop loss below the obvious support and resistance level by a factor of maybe 10%.
This may require smaller trade size, but overall will allow the trade to hopefully avoid these potential stop losses. Treat support and resistance as areas instead of specific price points. Support and resistance do not exist at one price and rather a range of prices that are supply and demand zones.
Therefore, placing stop losses below these 'zones' may put the trade out of arm length of stop hunters. Simply being aware of stop loss hunting may provide some reassurance when a sharp spike in price occurs, to remain in the trade and not exit immediately. Ultimately, Stop Loss Hunting is just another challenge that traders must deal with in the pursuit of profit.
However, with some knowledge traders can adequately accommodate these tricky occurrences.


Mean reversion strategies are some of the simplest trading strategy’s used by sophisticated traders. However, when most traders hear the term, they immediately get confused. So, what is mean reversion and why do traders use it as a strategy?
Mean reversion is the tendency for the price of an asset to move back to its long-term average or mean after explosive moves to the up or downside. Traders can therefor capitalise on the end of these explosive moves by going long when the price has broken down and will revert up to the mean or short when there has been a strong move to the upside and the price will fall back to the mean. This strategy is often compared to trend following strategies in which the price tends to moving solely in one direction over a significant period with traders entering at the lows and exiting at the highs.
Mean reversion strategies can actually be used conjunction with a trend following strategy as trend following strategies will often pullback to the long-term mean. What is the mean? The mean is quite simply the average of a price over a time period.
In trading, the average can often be shown by using a moving average of mid points of ranging price. For instance, on a long term a significant average that is seen as the mean is the 200-period moving average. The 200-period moving average is used so often because of its length.
It provides an average over a significant period of time. Other averages that are often used include the 50 Period moving average and 100 period moving average. All three can be used in different ways to measure different reversions to the mean.
On a shorter timeframe, the Volume Weighted Average Price of VWAP is often used as a short-term measure of the mean as it adjust the price for the volume traded as well. What is the premise behind the strategy? The idea behind the strategy comes from the basic principles of supply and demand.
The price of an asset adjusts up and down until the there is a point of equilibrium or where the buyers and sellers reach a stalemate which then becomes the mean. Economic principals say that over time at some stage this phenomenon must occur. Therefore, even if the price of an asset or exploded, at some stage it will have to revert to the mean.
In addition, this process will occur regardless of the time frame. Over longer time frames, the process will still occur, although it may take much longer. For instance, if looking at the daily/weekly time frame, the process may take days and weeks to eventuate.
The examples below show how a simple mean reversion strategy can bring about large potential gains. Whilst this strategy can be extremely profitable it can also be risky because it can contradict some of the psychology that trading is built on especially in the short term. The mean reversion strategy requires the market to price assets based purely on the long-term supply and demand and markets do not always act rationally.
Emotions such as fear, and anxiety rule the market which lead to price action that can put pressure on these types of strategies. On both examples, after significant price movements towards the upside and downside, the prices peaked or bottomed and then returned to their long term mean indicated by the blue 200 period average.. Utilising a mean reversion strategy can provide high return opportunities for traders who can master the skill and strategy.


For new traders, it can be difficult to know which indicators to use, the saturation of various moving averages, RSI’s, MACD’s and more can be overwhelming and counterproductive. However, utilising relative volume, as an indicator is one of the most important sources of information for technical traders. What is Volume?
Volume is quite simply, the volume of the asset traded over a specified time. This volume is usually shown by bars, generally located at the bottom of a price chart. Each bar represents one unit of the corresponding time period’s volume traded.
It also shows whether the period ended in the green or red. Volume tends to be reflective of the interest in the asset and is therefore a valuable tool. Why Relative volume?
Now that there is a clear definition of what volume is, understanding relative volume is straight forward. It has been established that volume is indicative of the amount of the asset traded for that time. Essentially, most assets will have a consistent or average volume that gets traded over a specified time, whether it be an hour, day, or a week.
Generally, the longer the time frame, the more weight a trader should give to that average. A large spike in the volume relative to the average is what a trader should be looking for. The volume bars are the best indicators of this.
Larger volumes can indicate larger positions being taken and increasing interest. Therefore, increases in relative buying volume can be a leading indicator for a move to the upside. On the contrary, a large red volume bar can be a leading indicator that price drop is about to occur as a large position is exiting.
A rule that many retail traders like to use is to follow the “big money” or institutions. Big institutions cannot just enter or exit their positions quickly like retail traders. Therefore, these institutions leave a trail of their entries and exits, that experienced traders can capitalise on and follow.
Understanding how shifts in volume can indicate, potential break outs, break downs and reversals takes time and practice but is a valuable tool that any trader should utilise to improve their entries and exits. A few examples of volume indicating changes in price action. Apple's sharp increase in selling volume indicated the ‘top’ and has not reached those high since.
Similarly, the chart for Brent Oil showed a similar pattern whereby it could not breakthrough a long-term resistance level and combined with a large volume of selling signaled that the price had peaked. The price for Stanmore Resources saw a big push after the influx of new volume and has its price increase since the first candle. This may indicate that institutions have added the company to its holdings or that significant buying interest has returned.
Further way to optimise using relative volume Anticipating Relative volume shifts by understanding that they tend to follow on from big news events, such as unexpected results or broader macro factors. Combining big volume shifts with a break of a key support or resistance level Combining with other technical indicators. Use a collection of volume bars vs just one to see the shift in relative volume
