How to select MQL4 Expert Advisor for your MT4 automated trading account

MetaQuotes Language 4 or MQL4 is a programming language that comes with Metatrader 4 or MT4. It is use to write and test Forex Trading Strategy into computer program which can run on MT4 trading platform. There are many automated trading software and here are some tips that can help you select the best Expert Advisor.

Expert Advisor are created from programming language and tested in MT4 strategy tester. The program language use is similar to C and uses a text editor for coding. The Strategy tester use historical data to test the program and out put the summary results at the end of the testing. User can choose the duration of the back testing period, the currency trading, the time period chart to use and the various algorithm testing model to use.

Back Testing Results that matters.

Many people with programming background can program any strategy into codes call Expert Advisor and let it trade for you automatically. Letís look at some of the back testing results before putting it to run on live trading account.

Profit Factor

This is the first important results to look our for, which is the profit factor. This determine the total winnings divide by the total losses. Anything more then 1 yields profit in the long run. But due to market conditions and trading news outbreak, a profit factor of 2 is more desirable. Anything between 1.3 to 1.8 have to be reinforce with multiple strategy as backup to one another.

Max Draw Down

Draw down is the lowest loss at any point of time the account is trading. Maximum Draw down simply means the maximum lowest amount you have in your capital at any point of time (realized or unrealized profit trades). This is extremely critical to your setting configuration to avoid margin call out. General rule is good to have an EA that product less then 20% max drawn down. Anything 50% to 21% is dangerous and have to be properly set to avoid margin call. Nothing above 70% as it is too risky.

Expected payoff

This figure measures the gross profit, gross loss, the duration and the initial deposit. The highest this figure is the better and more profitable is your program. Anything that is more then 100 or 150 will yield profitable results.

Duration of testing

It is important to test the strategy for at least 12 months of historical data as it covers major news release and season changes for majority of the traders. Forex prices will change when fundament news like Non-farm payroll or unemployment rates are announced and the market will react according to forecast difference. During holidays break in United States and Europe and Japan will also affect the volume and forex prices will rise and fall aggressively. The EA have to be tested thru all these events for the year.

Max and Average Loss

Am not looking at winning trades but more on losing trades as this is important for margin call and setting it to run with other automated forex program. Avoid EA which have zero or have little losses, instead look at average loss that is no more then your winnings trade. It may have large losses but on the whole in the long run, averaging it will give small loses and gain your profitable income.

Last Words

There are other factor like short position, long position, consecutive loss, modeling quality, are equally importance but I put them secondary to Profit factor and Max Draw DownFind Article, which I focus mainly when select expert advisor to run my automated trading account.
