Discuss EA Makes MetaTrader slow after sometime

[shanmugapradeep]

Hello,

I engage in algo trading with the assistance of an EA using Metatrader 4. However, I've encountered an issue where my MT4 becomes extremely slow after a few weeks due to the accumulation of temporary files from Metrader 4 and the EA. The EA consistently places a large number of objects on the chart.

Could you please provide a solution for this?

1. How can I clear the temporary files and caches of Metatrader 4, as well as remove objects from charts?
2. If I regularly clear temporary files and caches, will this affect the operation of the running EA?

Thank you.

Make sure that MetaTrader 4 is closed before proceeding.

Typically, the data folder is in C:\Users\YourUsername\AppData\Roaming\MetaQuotes\Terminal\YourBrokerID.

Is this an EA you purchased? Or do you own the source code of the EA / program it yourself?

If you program yourself, you can create an option to delete objects after xx days or hours. and 0 would mean deleting the object immediately after the object is created. This should also be done when running tester mode also. But when running in visual mode, you could turn this on so you can see the objects. But try to limit it to just a couple of days or weeks....especially if you are making 20+ trades per day and have many complex functions that need to be recalculated onTick()

Now if you DO NOT own the EA, you could create some AutoHotKey or AutoIT script to interact with the terminal and clear out the chart objects daily or as often as you like. But this is not very ideal....this should be done at the source code level.

2. If I regularly clear temporary files and caches, will this affect the operation of the running EA?

you could run a CMD script to delete and/or zip these files to keep the hard drive space lite. Now the current day's logs would be locked. But other days would zip or delete just fine. If you need to preserve logs for a period of time (like 2-4 weeks), zipping is a good compromise that saves space.

also, always run your metatrader terminal in /portable mode. And keep everything in the install folder. And install mt4 outside of program_files folder. This keeps everything organized and in one place, with as little Windows OS interference as possible.


FPA forum is usually not the best for technical problems on programming EA. MQL4 , ForexFactory, and even stackexchange would be better solutions.

Freelancer programmer created for me based on my requirement. I have source file.

If you program yourself

I am not a coder but i can understand a little

you can create an option to delete objects after xx days or hours.

I did but it not working, Here is my code

// Timer function to clear all objects on the chart
void Timer()
{
    // Iterate through all objects on the chart and delete them
    for (int i = ObjectsTotal(); i >= 0; i--)
    {
        string objName = ObjectName(i);
        if (StringLen(objName) > 0)
        {
            ObjectDelete(objName);
        }
    }
}

// Initialization function
int Init()
{
    // Set a timer to call OnTimer() function every 5 min
    EventSetMillisecondTimer(5 * 60 * 1000);
   
    return(0);
}

// Deinitialization function
void deinit(const int reason)
{
    // Clear the timer when the script is removed
    EventKillTimer();
}

// Main execution function (not used in this example)
int Start()
{
    return(0);
}

EAs always double the trouble especially when you are not a coder..

EAs, properly coded, reduces the amount of manual work required to watch charts or give instructions.

share your problem and code on the mql4 forum. There are others like stackexchange and forexfactory.
