ERROR 4805 It's not a coding error, but CPU, cache memory problem in MT5
This is not a coding error. This is an error to do with your CPU and MT5 cache (temporary memory).
This is only a problem with the multi-symbol EAs; old CPUs, old chipsets, Computers with less than 4GB Ram.
This problem is easily solved, once solved you won’t have a problem as cache will remember correctly.
This can happen in the Strategy Tester Or when loading on a chart for live trading.
Both have different Solutions.
” Now you have loaded all your EAs with No 4805 Errors. Restart your MT5 terminal and you will see it will always load your EAs with no problems, that is because the profiles cache (temp memory) is set correctly ! “
MT5 Strategy Tester Solution
Close down all programs running on your Operating System.
Restart your MT5 terminal. Make sure your data goes far enough back for the symbols
and custom dates you have chosen. View > Symbols > Bars,
to see you historic data.
MT5 Live Trading Solution (when putting EA on a Live chart)
Restart your PC/Laptop.
Open MT5 Terminal, no other programs. MT5 will open with the last settings you closed with and we want a new cache (temp memory) .
So File > Profiles > Save As..> name your new profile > close all charts > open a new chart, just 1.
Drag & Drop EA onto the chart M5 (or H1 for conservative set files),
there should only be 1 chart open> Load SET Files> OK
Now do this for other charts you want to add and remember to add unique Magic Number to the new EA.
Now you have loaded all your EAs with No 4805 Errors. Restart your MT5 terminal and you will see it will always load your EAs with no problems, that is because the profiles cache (temp memory) is set correctly !!!
