How to do this, hide trailing stop loss, no stop loss?
I have a MQL4 library that my EA uses. The library has several variables declared on a global scope as well as functions. The content in these variables are preserved between calls to the library.

  Virtual Stops (6)
Hi, I am writing code from scratch and keep being told that I should be building in Virtual Stops so my orders are 'invisible' to brokers. Problem is I have no idea where to start; None of the books I have discuss it and all the posts I have found on the subject are fairly dated with conflicting...
Hi there, I want to create a dll in C#.

I coded an indicator that works on my mT4 and gave it to a friend and it works on his as well. He gave it to a third party who is using interbank FX mT4 and everytime he attaches the indicator his mT4 freezes and closes. What are possible reasons on why this is happening?
This is not programming related, so please humor me on this one. Don't you find it annoying that price is going up when your indicator is going down? I used to think that the best way to counter that was finding some magical adaptive window function (that changes the look-back length of your...

Folks, the data coming out of Metaquotes servers is garbage. This problem has been going on for almost 2 years now. I really dont see you any of you can expect to make money when the data used to backtest is full of holes. The Metaquotes History and how it fills charts in MT4, combined with your...
