The most powerful and effective aspect of forex trading is in general its Leverage. This gives you the flexibility to take significant positions in key currency pairs without adding too much capital, and maximizes the amount of any profit you make. However, Leverage can be risky. If you are wrong about a trade, it magnifies your losses. At excessively high levels, leverage exerts another effect. In addition to simple magnification of P&L, it begins to materially damage your odds of success on any particular trade.
Before enter into trade you should fully understand the impact of leverage, and the circumstances under which it can significantly damage the probability of a trade being profitable. And we also believe that allowing excessively high levels of leverage is not in the interests of our clients, our firm or our industry, and we have set our margin levels accordingly.
How does high leverage impact your trades?
This graph shows how excessively high leverage acts to distort the probability of your trade being successful. This distortion is the result of the way leverage interacts with transaction costs (spread and funding).
In the absence of transaction costs, the leverage you use has no impact on your probability of success. If you were to place trades randomly, without any particular insight or skill, and aim to take profits of the same size as your maximum stop-loss, you’d tend to win on 50% of trades and lose on 50% trades. This would be independent of your leverage used, and is represented by the dotted horizontal line on the chart. Transaction costs change this picture, representing a hurdle between you and a profitable trade. Another way of saying this is that costs shift the odds against you. At most levels of leverage this shift in odds is small.
However, when the leverage you use is so high that the margin supporting your trade is less than 10x to 20x your costs, your probability of losing begins to increase very rapidly. This is because costs eat away at the supporting margin, leading to a high probability of being closed out. This is easy to understand if you think about the most extreme case, where your supporting margin is exactly equal to your transaction costs on a trade. You’d place your trade, and the transaction costs would leave you with zero supporting margin for your position. This would lead to you being closed out immediately, with 100% probability, every single time – regardless of your trading strategy or how the market moves.
Now we want to take a harder look at “leverage” and show you how it regularly wipes out unsuspecting or overzealous traders. We’ve all seen or heard online forex brokers advertising how they offer 200:1 leverage or 400:1 leverage. We just want to be clear that what they are really talking about is the maximum leverage you can trade with. Remember this leverage ratio depends on the margin required by the broker. For example, if a 1% margin is required, you have 100:1 leverage. There is maximum leverage. And then there is your true leverage.
