I'm a newb at this but I have some programming experience.

to import the data into mt4 so you can bactest with the strategy tester, follow theese intructions

to use mt4 to backtest, there is a window called the strategy tester, and you can plug in which ea you want to backtest, and set which currency pair and timeframe you want to backtest it over, and how long.
however, there are many downsides to the strategy tester, they are still all over this forem, here's a fe things i've mentioned earlier about only a few of these problems.

First of all I am not a programmer but I am a novice trader. I see several price patterns that tend to repeat itself frequently. I want to write a program that would take these trades each time. The purpose of my EA and back testing is to tell me whether my observation in correct i.e. percentage of win, profit to risk and frequency.

YES, BACKTESTING IS IMPORTANT, the problem is, the strategy tester that METATRADER4 created has a multiple number of limitations, they were noted all over the place over the past month. just look for them, mostly in the metatrader4 and expert advisers metrader 4 forums, just know that you are not alone, you're doing nothing wrong, it's just a crappy automated tester. which i why i manually backtest, even though it takes time and patience, it is well worth the effort to get accurate results, (but that's just my oppion  ).  |
now to finish your last question, the tester will run which pairs you trade in by which one you select in the tester window, and will run as you will set it, but why you would want to base descision on one currency pair from the results of another is beyond me, as if there is ANY relation, there is very little.
