forex trader profitability statistics and probability

Yes. Totally agreed with the number of trades will increase the probability of profit if your winning rate is greater than losing. Eventually the losing trades. If one does not understand how the currency rates go up and down, he can never be a good forex trader. For understanding the market the subject of statistics is. Let's say that out of 10 trades you place, you profit on three of them and realize a loss on seven. Your probability of a win is therefore 30%, or , while.

Some traders may assume that the system will win over time, as long as there is an average of at least one profitable trade for each four losing trades. Yet, depending upon the distribution of wins and losses, during real-world trading this system may draw down too deeply to recover in time for the next winner.

A positive Z-score represents a value above the mean, and a negative Z-score represents a value below the mean. To obtain this value, the trader subtracts the population mean from an individual raw value then divides the difference by the population standard deviation.

Z represents the distance between the population mean and the raw score, expressed in units of the standard deviation. So, for a forex trading system:. N is the total number of trades during a series; R is the total number of series of winning and losing trades; P equals 2 x W x L W is the total number of winning trades during a series L is the total number of losing trades during a series.

R counts the number of such series. Z can offer an assessment of whether a forex trading system is operating on-target, or how far off-target it may be. Just as importantly, a trader can use Z-score to determine whether a trading system contains fewer or greater series of winners and losers than expected from a random sequence of trades— In other words, whether the outcomes of consecutive trades are dependent upon each other.

If the Z-score is near 0, then the distribution of trade results is near the normal distribution. The score of a sequence of trades may indicate a dependency between the results of those trades. Whether the Z value is positive or negative will inform the trader about the type of dependence: A positive Z value indicates that the profitable trade will be followed by a loser.

And, positive Z indicates that the profitable trade will be followed by another profitable one, and a loser will be followed by another loss. This observed dependency lets the forex trader vary the position sizes for individual trades in order to help manage risk. The Sharpe Ratio, or reward-to-variability ratio, is one of the most valuable probability tools for forex traders. As with the methods described above, it relies on applying the concepts of normal distribution and standard deviation.

It gives traders a method to check the performance of a trading system by adjusting for risk. Likewise, HPR can be calculated by dividing the after-trade balance amount by the before-trade amount. AHPR by itself produces an arithmetic average which may not properly estimate the performance of a forex trading system over time.

The concepts of normal distribution, dispersion, Z-score and Sharpe Ratio are already incorporated into the logarithms of EAs and mechanical trading systems, and their usefulness is invisible to most traders. Yet, by knowing how these basic probability tools work, forex traders can have a deeper understanding of how automated systems perform their functions, and thereby enhance the probability of winning trades.

Reliability of analysis depends on quantity and quality of data When modelling normal distribution curves, the amount and quality of input price data is very important. Dispersion and mathematical expectation to estimate risk For forex traders, the most important characteristics of a distribution are its mathematical expectation and dispersion.

For example, below is a sample risk assessment for a test of a forex trading system: Trade Number X Trade Gain or Loss 1 Z-score Beyond the riskiness of a particular trading system, forex traders can also use normal distribution and standard deviation to calculate the Z-score, which indicates how often profitable trades will occur in relation to losing trades. Sharpe Ratio The Sharpe Ratio, or reward-to-variability ratio, is one of the most valuable probability tools for forex traders.
