MQL5: Using custom indicator in strategy tester to debug an EA.

I'm finally making a serious attempt to convert my MQL4 codebase to MQL5. First, I'd like to mention this: what a freakin' nightmare this conversion is. That said, after a brutal 3 day effort to convert one of my primary indicators to MQL5 - I have achieved near similar results with its MQL4

Share Class data from EA with [to] an Indicator

So I have a Class Object (TickMA) that aggregates tick data in proprietary fashion. The class object is instantiated and updated from my EA. Problem: I want to visually present data contained in the EA Class to an separate window indicator. Looking for a way to pass the pointer from the EA to the

Best Practices for json Implementation

I have fiddled about looking for design concepts to implement visuals of the data collection, aggregation, et al (pics below). As much as I love the MT4/5 platform, visuals are not its strong point. First, real estate is expensive; Second, I/O overhead on graphics rendering is high - the more

OOP Conundrum

Hi everyone - So, my MQL4 days are slowly coming to an end. My broker has implemented MQL5 and now, the conversion from 4->5 begins. When I started MQL4, I was an OOP noob and in some respects, I still am. Building OOP classes has certainly paid huge dividends by creating a foundation of thoroughly

Indicator plots in separate window

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

6th Degree Poly Help!

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

Urgent - Array exception on Close[0]

Don't know if it's my broker, but, this should not be possible. I am getting an array out of range exception when attempting to access Close[0] - Don't mind the issue per se, but, the lack of ability to trap the exception so that the EA doesn't crash is not acceptable. Thought maybe it would happen

MQL4 Debugger using history

Anyone know how to use this functionality

Constants in Classes

Hi all, Having a bit of trouble with the OOP implementation - I will say this first, I am a noob when it comes to OOP. I want to define the following array as a global constant: private : static const double FibonacciLevels[ 6 ] = { 0.0 , 23.6 , 38.2 , 50.0 , 61.8 , 100.0 }; Clearly, these
