Is there a way to programmatically, or using Settings on MetaQuotes, to have an EA automatically selected and run on a chart? It would be nice if the account could be set up to automatically select a Chart currency, timeframe and an EA to run on the chart whenever the account is started. How is this

I have discovered that during MT5 backtesting, when a symbol's swap type is set to "in percentage terms," the swap fee is calculated as zero. This is likely because the value is too small and the program rounds it down to zero. Taking ******* US100 as an example: the current price per lot is

Hello, I’ve developed a custom EA that has a maximum memory footprint of 1.5GiB per agent/thread when running locally.

Hello All, I've seen this mentioned in various places, but I haven't been able to find a solution on any of the threads that have worked for me. When I run a optimisation session on my EA, the "backtest" results section matches up with the "run single test" perfectly everytime, whereas the forward

Repost with photos... I am using a custom symbol with imported tick data and am testing the spread option where it lets you input your own desired spread number.

Hi,  I try to program  a simple script.  My question: How do I get the value of the ATR (average true range) indicator in a script? I've found the function "iATR" (https://www.mql5.com/en/docs/indicators/iatr) but it does not return the current ATR value. Any ideas?   Thank you. Best, Chris

I have recently run some 1, 3 , 5, 10 and 15 year back tests with my EA. I came across something I have never noticed before and I am pretty concerned about it. I ran a backtest from Jan of 2015 to Current data and my maximal DD was at roughly 10% See picture one. But when I run from 2015 to 2020

My Expert Advisor (EA) supports multiple virtual trading "agents", each with different trading parameters and lotsizes. The Expert Advisor ID ( magic number) is a parameter in the MqlTradeRequest input structure to OrderSend (). It would be very useful to be able to distinguish the various trade

I have a mqproject (consisting of a MyEa.mq5 and a .mqproj file within the folder called "custom") and would like to use indicators from MQL5/Indicators/Examples in my EA. With a simple EA without embedding it in a .mqproj , indicators can be loaded successfully without the need to include them
