It's seems that on build 940 there is a bug using Global Variables: when you add manually a GV all is ok, and you can perform normally other functions (modify and delete). But if you close the platform and reopen it you loose all changes. Probably there is some problem with the copy of changes on...

Hi there,   Its mostly a theoretical question (but example code is always welcome).   The real question is: how to correctly code the 'frame' of an EA that tests multiple scenarios from multiple custom indicators? The way I'm (busy) building an EA, is not very much focused on 1 strategy, but is...

Hi 1. In MQ4, I understand that there is no concept ofclasses and structs. The only way I found for holding lot of data is arrays(buffer) or save to a file. Is there any other way? 2. It doesn’t say anywhere but I wasn’t able toreturn an array from a function. Is it the right behavior?...

It's not easy to see the used Margin of an order if there are a few orders opened.  1.  Is there a simple way to get the used Margin of an order? 2. If there is a short order of "Eur/Gbp" and my account money is "Usd", should I use the bid or ask price of "Eur/Usd" to calculate the used margin? 3....

I've written a large number of indicators and they are fairly robust. I have always followed a pattern to display all but one of the buffers in the main chart window and reserving 1 buffer not to plot but to store measures that are calculated for and retrieved by a given EA. These measures aren't...

Hello! In a loop I want to assaign the values of the operator to specific arrays depending on the loop-variable. This is a simplified example:  ---------------------------------------------------------------   double Array1[1], Array2[1], Array3[1], Array4[1],...;  for (int i=0;i<=100;i++)...

Hi, I've come across on something weird. Having an extern input variable followed by comment changes the name of the variable in the EA's/script's Inputs Window. The following code: extern string myVar = "abc" ; // This is a comment extern double d = 2.5 ; /* Another comment */ compiles fine and
