Hi Rayner,Nice post on position sizing and money management. In your experience, did you always start with a 1% risk exposure? I am currently figuring out whether it will be good to scale down my risk during bad streaks and scale up during good streaks. Also do you take equity off after every year or do you continue to trade with your ending account balance while maintaining the same % risk exposure? Thanks.
Hey Rayner,I have some confusion , please help me to understand the position sizing concept.Suppose I have $100000 trading capital.I am risking 1% on each trade.As a trend follower I will trade every winning position till it is in trend.Position sizing is allowing me to take 10 to 15 trades with $100000/- capital.Is it necessary to take more trades to get more %return?If I took 5 trades from that 3 are winners and 2 are looser.Can you please explain as trend follower how to trade these 3 winners with $100000 capital.
Hello RaynerFrom your explanation does it mean that there are two methods in calculating stop loss1. That is through position sizing2. And through locating where your initial trading idea is invalidated
And why not? Without proper position sizing techniques you could be risking a big chunk of your trading capital. Ultimately, the bigger risk you take in every trade the bigger the chances of your trading account being cleared out.
Let's look at exactly what position sizing is and why it's so important, as well as dive into the best position sizing techniques you'll need to become acquainted with in order to improve your trading.
As you can imagine, opening positions with random position sizes or based on gut feeling will eventually end in disaster. Position sizing is about preventing excessive losses. If you have a sound risk management plan and follow it, chances are you will not lose a significant portion of your capital on a single trade. It will also give you a chance to keep your focus on your account as a whole and all your open positions. Especially for short-term traders who have to react quickly to new developments, it can be easy to lose oversight and forget how much risk they already have running before they open further positions. This is why it is crucial - a good trader is also a good risk manager.
However, position sizing is not only about preventing excessive losses. It also gives you the opportunity to maximise your performance. A risk-averse trader who is only willing to risk a tiny percentage of his capital will have to accept the fact that they will never achieve notable returns. As you can see, position sizing is about finding the right balance - allowing yourself the opportunity to maximise your profit while preventing excessive losses.
Fixed dollar value can be the simplest way to implement position sizing into your trading strategy. This may work particularly well for those who are new to trading or who have quite a limited amount of capital. All that it requires is to allocate a fixed dollar amount to every trade that you take.
Fixed percentage risk per trade is the most commonly referred to position sizing technique used by traders. You risk a small percentage of your overall capital on each trade. It is an anti-martingale strategy, which is the preferred method for financial instruments like forex.
It is important not to abruptly change or mix different position sizing techniques, but rather to have a proper plan in place and ensure consistency. A demo trading account is the perfect solution if you need more time to explore which method is the best fit for your trading style.
Position sizing can reduce risk in different ways. For example, a trader who decides to take a large trade and risk 20% of his capital on it because he felt lucky or he thinks this is the big trade that will make him rich will struggle to keep a cool head. Most likely, he will start to feel immense stress once the position starts to move against him. Or, if it moves into his favour, he will panic and close the position to make sure he closes the trade in profit, even though the trade might continue to run 50 or 100 pips in his favour.
If you have a sound plan in place and are using appropriate position sizing techniques, you will end up with an amount of risk that is reasonable for you, and in return, it will be much easier to view your positions objectively. You will be in control, rather than reacting emotionally.

Position sizing is probably the least talked topic, but one of the most important one as it will determine your max drawdown and risk of ruin. And you guessed it, using R & R-multiples makes it easier to know what kind of position sizing would be appropriate for your needs.
R & R-multiples can allow you to optimize your position sizing to your needs, instead of, for instance, using an arbitrary position sizing that could potentially have too high of a chance to lead you to ruin.
Like any concept in trading, R & R-multiple are not foolproof, nor are they the Holy Grail. They are a useful tool that can give you an approximation of what to expect and a mental edge. There can be a big discrepancy between the results you get and what can expect, especially given the fact that it is possible that we get filled at a much higher (or lower) price than the price we based our position sizing on.
The risk management aspect of a trading plan is where position sizing becomes very relevant to a forex trader interested in being in business for the long term, and that will be the focus of this article.
Strategically, proper position sizing in forex trading helps a trader lower the inherent risk involved in taking on a forex position in a fluctuating market. The amount of risk to be taken on each trade is a typical part of the money management aspect of a trading plan. A sound trading plan would ideally specify the position size of each trade according to some objective criteria the trader feels comfortable with.
Forex traders generally have their own unique approaches to taking risk and can choose to follow any number of different position sizing methods that should be explained in detail as part of the overall strategy outlined in their trading plan.
The main risk in this position sizing method consists of the potential drawdown on the position in its initial stages. If the position incurs a severe drawdown initially, the account could take a considerable blow to its balance. To make the technique work properly on the downside, the drawdown should not exceed an amount specified beforehand.
In a fixed risk position sizing method, a trader might determine the size for trades made in their account based on the risk of trading in a particular market as assessed by using a suitable risk measure such as volatility. In this method, they might take smaller positions in riskier higher volatility markets and larger positions in less risky, lower volatility markets.
Furthermore, with the fixed risk position sizing, the size of the trade is a function of the some measure of market risk, rather than account balance, so profits or losses do not show a consistent type of equity growth or loss.
The disadvantage of this type of position sizing is that risk measures can easily change significantly due to a market shock that occurs while a trading position is being held, and a method for dealing with this sort of shift needs to be planned for in the trade plan. Adjusting the position size may be appropriate in this situation.
This type of position sizing also lends itself to being combined with a fractional position sizing technique so that when the equity in the account rises due to profits that have been accumulated, the size of the risk weighted position increases proportionally. Conversely, when the equity in the account decreases, the risk weighted position size also declines.
As part of their preparation for starting to trade a trade plan, it typically makes sense for a trader to create a forex position sizing calculator if their plan calls for anything other than simple fixed lot position sizing.
Due to the extreme volatility inherent in trading currencies, the selection of a suitable position sizing technique can be crucial to the success of a forex trader. The first and foremost consideration for position sizing and trading forex in general is to survive to trade another day, and that can only be done by managing risk appropriately. Success is secondary, since not being able to trade basically eliminates the possibility of being successful.
Depending on the position sizing method adopted, the trader must calculate lot size, risk parameters and/or the percentage of equity in the account for each trade. Each trader is different and everyone has their own approach for money management, some of which perform better than others over time and in different situations. A position sizing technique that works for one trader, does not necessarily work for another trader using a different trading strategy. 2b1af7f3a8
