Hello, I'm learning mql4 and tried my first EA. I did a Backtesting. I found that my expert was sending a lot of orders at the same next bar once the buy/sell condition was given. The problem is that I programmed it to work with just one market order (i.e. system must be always buyed or selled)....
Hello Forum, possibly my most ignorant question, but then again I don't know! As a newbie I find myself putting a lot of descriptive text in my code, to remind me of what I am trying to do and allow me to come back to rework errors etc In the more complex work, this might be 100 or 200 lines of...

My EA uses Open[0] and Close[0] on the M1 chart and then compares the two values to determine whether it was a bull or bear candle. For some reason the backtester returns the same value for these two operators. The same is true for iOpen(.....,0) and iClose(......,0) How do you resolve that?
Hi, I want to test a strategy from 1.1.2008 till 1.1.2012. The minute datas and also the upper timeframes are there for that time, but my strategy tester runs only for the first 6 month and so I have to split the testing time. What's the reason?
