MT4 is widely used for Forex trading and one feature I personally like about metatrader 4 is the MQL programming language that comes with it. This programming language allows you to codes your favorite profitable trading rules into programs called expert advisor and let it run on your computer automatically.
Expert Advisor
MQL4 is basically a programming language that is similar to C and it is used for coding strategy into program. The program which can be set and run in MT4 are called Expert Advisor or EA. Expert Advisor is lines of codes that run on your forex trading account and simulator strategy tester is used to test the EA using historical price data. The results report from the strategy tester is used to fine tune the strategy and in order to select the best Forex trading program EA, below are some indices that need to be check.
Return on Investment (ROI)
This is a measurement of the price capital that you invested in your Forex trading with the profit return that you gains over a certain time which is a measurement against it. A 100% return over 1 year is a very good indicator that it able to give you 1 dollar profit to 1 dollar invested. When compare to bank saving account interests and stock market and unit trust, 100% return is many times better. For Expert Advisor, minimum 20% return annually is desirable. Any figures less then that is not worth your investement.
Profit FactorThis is calculated by dividing the total profit by total losses. A simple indicator but yet a powerful indices that show over all the time, how profit is the program. A profit factor of 2 means you earn 2 dollars for every 1 dollar you loss. Most program gives profit factor of 1.5 to 2. If you find software that gives more then 2 or 2.5, please grab them immediately. You will never loss out on this measurement.
