In other words, if I have an open Buy order at price P1 then: my profit at P2 would be ((P2-P1) * volume) - but that's in most simplistic terms, now I need to...

However, in the script I wrongly initialize  histroyPOS=0. I found a bug after the new script opened an order and closed it soon in my...

I'll provide the details of EA once I am on the appropriate path. Could you help find a programmer through MQL4 because I don't want to pay anyone while there...

I have been away from the market for about a year. I found this indicator and liked it. My system kept locking up and freezing and the problem was this indicator. I put in and ran a compile on it and it had 16 warnings. So I fixed the warnings. I changed the alerts to false for personal preference....
Hi all, I am pretty new to MQL4 and have a question about polymorphism in MQL4 which think will be most clear if I show some C# code of what I am trying to achieve: class B{ public void X() { }}class C<T>{ protected T t;}class D : C<B>{ public void Z() { t.X(); }} So, from...

This will be changed for future purposes. The file writes properly and saves as I...
Python has superb libraries for data handling, math and machine learning. Enabling direct integration with MT4 for algorithmic trading would be a big win, enabling the large number of existing Python programmers to just get to work. 
There are frequent questions in this forum (e.g. 'Difficulty using FileReadString on file opened outside /experts/files') about reading and writing files anywhere on the hard disk, but there only seems to be one published library for doing so, and it's fairly limited: 'File Operations without...
