So, the effective leverage in this example would be expressed as Brokers in the United States offer upto leverage for forex trading, while Forex brokers in other jurisdictions can offer leverage upto in some cases. But is very important to keep in mind that leverage should be used responsibly as it acts to not only amplify returns, but also magnifies losses.

Position Sizing is one of the most important and frequent calculations that you will need to make as a forex trader. In fact, before any trade that you consider entering into, you should calculate the proper position size based on your pre-defined position sizing model. One of the simplest and most effective position sizing models is a fixed fractional model.

Once you have determined how much you plan to risk on a per trade basis, then you would start by determining where the most logical stop should be placed on a particular trade. One you have located a level where you plan on placing your stop loss , measure the distance in pips between this level and your intended entry. Then jot that number down and keep it handy. Now the next step is to determine the value of each pip.

We have discussed how to calculate the value of a pip in the previous section. Once you have this value, you are ready to calculate your position size. Here is the trading math behind Position Sizing:. Trade Expectancy is one of the most important metrics that a trader should be aware of. But what does it mean?

In a nutshell, trade expectancy is the average profit or loss that can be expected on each trade based on your average Win Percentage, Avg Win Size and Avg Loss Size. Here is the mathematical formula for Trade Expectancy:. Typically trend following systems tend to have low win rates, but relatively large average wins compared to average losses.

This time we will look at a Mean Reversion strategy. Mean reversion strategies tend to have higher win rates, and the average wins and losses are somewhat similar. Many traders make the mistake of only relying on win rates when evaluating trading systems.

How many times have you entered positions in multiple currency pairs and noticed that their price movements were related? To understand this better, you have to know what currency correlation is and how it can impact the overall risk in your portfolio. Currency correlation is a statistical measure of how different currency pairs move in relationship to each other. Currency correlations can be positive, meaning that two currency pairs move in the same direction.

Currency correlations can be negative, meaning that two currency pair move in opposite directions. And finally, currency correlation can be neutral, meaning there is no discernible price relationship between the two currency pairs. The forex mathematics behind currency correlation can be quite complicated, so we will not get into that in this lesson. But fortunately for us, we do not need to know the trade math because there are many currency correlation tools available in the market that makes it easy for use to do our correlation analysis.

Most currency correlation tools are presented in a table format. Remember that a positive value means that the pairs move in the same direction, while a negative value means they have an inverse relationship. As traders, we know that we will have losing trades and that they are a natural part of trading. Essentially, maximum drawdown is the maximum loss in equity that our portfolio incurs over a period of time.

It is the largest drop from a previous equity peak to the lowest point after the peak. We can calculate the maximum drawdown after a new peak has been put in place on the equity curve. Here is the math formula for calculating Maximum Drawdown:.

What is your Maximum Drawdown in this scenario? So, the Max Drawdown in this case is Drawdowns can be very dangerous to the financial health of a trader because, as your drawdown increases the return needed to recover becomes larger and larger. Let take a look at the table below:. As you can see, the larger the max drawdown or capital loss the higher the percentage gain is needed to recover the losses.

This is one reason why it is critical for traders to trade small so that they can try to keep drawdowns to a tolerable level. I would venture to guess that most retail traders have either never heard of Risk of Ruin or if they have they do not really understand its power when it comes to risk analysis in the markets. Risk of Ruin is the likelihood or probability that a trader will lose a predetermined amount of trading capital wherein they will not be able to continue trading.

It could be any percentage that the trader determines will be the point at which they will stop trading a system. The Risk of Ruin is calculated as follows:. There are several simulators available for free that you can use to calculate the risk of ruin. The one we will use in our example can be found here. We will use the following assumptions and plug that into the Risk of Ruin simulator:.

If you hit calculate on the simulator, it will run the simulations again so the ROR number may vary a bit. Well the factor that we would have the most control over is the Risk amount, and so we should look to adjust that input. Ok so we will keep all the variables the same, except we will adjust the Risk amount to 2. What does that do? Well that looks like a winner. Profit Factor measures the profitability of your trading system or strategy.

In this math guide for Forex, here is a realistic example to illustrate this. Brokers can offer from leverage for forex trading up to But think twice before you accept any offer. It is true that leverage may increase returns but also increase losses. This is one of the most serious and frequent estimations that you have to make if you want to be a forex trader. Actually, before you decide to enter any trade, you have to calculate the position size.

We suggest you use one of the simplest calculations. It is a fixed fractional calculation strategy. Take it as the rule for the fixed fractional risk. So, you have to decide how much you can afford to risk a per-trade. When you make this decision you have to decide where to place the stop-loss. Take a look where the most current swings are.

Find support and resistance points. When you settle a level where you want to place stop-loss, you have to measure the distance in pips between this level and the entry you plan. Write down that number. Then, discover the value of each pip. And you can calculate your position size. The distance between entry and stop is pips. This is just an example and you will find different situations but the principle is the same. Save my name, email, and website in this browser for the next time I comment.

Profit Factor measures the profitability of your trading system or strategy. It is one of the most simple but useful metrics related to system performance. Profit Factor can be calculated in one of two ways:. A profit factor of less than 1 means that the trading strategy is a losing strategy. A profit factor of 1 to 1. A profit factor of 1. A profit factor above 2 means that the trading strategy is extremely profitable.

Can you figure out the Profit Factor of this system? This system has a Profit Factor of 1. This system has a Profit Factor of 0,97, meaning that this is a losing strategy. The concept of R Multiples was first introduced by renown psychologist Dr. Van Tharp. R Multiple sounds like an esoteric term but it is fairly straightforward and easy to understand. R Multiple essentially measures Risk to Reward for a particular trade. The indicator uses a special algorithm to find areas of trend reversal at an early stage, as well as to determine the points of renewal of the current trend before a strong movement.

The indicator can be used both as a ready-made trading system and as an additional precise filter for any trading system. No third-party paid or free analytics, signals, reviews will provide you with such valuable information and such accurate daily signals.
