MQL4 and MetaTrader 4 - page 603

Hi, I try to fix one EA, and make and indicator that shows OrdersTotal(), but when I do backtest and attach the indicator that shows total orders, the indicator shows NOT THE BACKTESTED EA's total orders, it shows the actual MT4 account orders. So, what the problem and solution?

Hi everyone, I'm new to the forum. I have an EA already designed, but wanted to refine it a bit and experiment more around it.

Hi,   Honestly I quite forgot how to program in MQL, was just trying to compile an old program of mine:        It is probably something very basic, I just want this program to work for now :-)     Would appreciate any help! 

Hello! For Christmas, my parents purchased an Ipad Mini 2 for me. I downloaded the MT4 app and have enjoyed it thus far.

Hi, Is there anyone here tried to run an Indicator using an EA? Thanks...

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?...

I remember mql4 community was closed in favor of mql5. Didn't know they have re-activated it again! So I posted my question on mql5 forums : MQL4: Sharing file between two MT4 on the same PC I checked a couple of topics for the same issue, but they didn't solve my problem. Any help would be...

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

I uploaded the .ex4 indicator to mql4>indicator folder but on the platform the icon of the indicator is grey and I can't apply it in to the chart anyone know how to fix it?  

If you want to fit a parabola (y=ax^2+bx+c) to e.g. the last 3 values of a buffer, you need to solve a system of 3 linear equations. In software like Matlab or R that is really easy to do, but how would you do it in mql4? I guess there is no function for this?

Let me introduce myself. I'm a database architect (as opposed to a mathematician) with very strong programming skills in all things database (sql, t-SQL, PL/SQL) and have enough skill in non-database languages (C,C++,C#, VB/VBA) to make do. I worked within the confines of the Financial Services
