This has been driving me nuts for a week now, hope someone can help. I have an indicator that draws entry lines at the top and bottem of the bar before an inside bar. It will also allow the user to elect to offset the lines, and to allow an additional offset to the buy indicator to account for the...

Are MQL4 arrays sparse? For example, if I define an array: double a1[][4]; Then add some entries at arbitrary points: a1[1234][0] = 3.14; Does the array implemention add entries 0 to 1233 for the first dimension? The purpose of this would be to track order specific information on a per ticket...

How can the Start( ) function be triggered by a certain period of time rather than a new coming tick? For instance, a time of 10 seconds. Can any one with kindness help me? Or More precisely, how can I perform a function(instead of Start( )) recurrsively triggered by a certain period of time?

I see that when I am running tests at the end the open orders are stopped out... sometimes these orders are -ve and of course that affects the final result significantly. Instead of closing out those orders is there a way to set MetaTrader to keep those orders open rather than stop them? Cheers C

Hi, is it possible to write an ea where I can choose which indicator is used? double iCustom( string symbol, int timeframe, string name, ..., int mode, int shift) iCustom is using "string name" to select the indicator, that means that it should be possible to use simply code like: extern...

I would like to request help in modifying the Parabolic SAR indicator. This should be easy for someone who is familiar with the programing language. I can trade but am brain dead when it comes to programing language. I would like the Parabolic SAR to emit an audible signal when it flips to the other...

Hi, I have had this problem bugging me for two weeks and I just can't figure it out: Made a special 'compund' indicator with one combined output (graph)...works great. But when I run the same calculations in the EA (obviously using arrays instead of the indicator buffers)  and drawing it using...
