This post mentions getting running MetaTrader 4 for Windows x86 in Linux with ARM CPU.
But when I actually tried it myself on Jetson Nano, it did not work. This is how to install wine and windbind:
sudo apt -y install wine-development winbind
And when I tried to run MetaTrader installer, I got the error:
0009:err:process:create_process L"F:\\home\\lissanro\\Downloads\\icmarkets5setup.exe" not supported on this installation (x86_64 binary)
wine: Bad EXE format for F:\home\lissanro\Downloads\icmarkets5setup.exe
The same thing happens with x86 binary:
0009:err:process:create_process L"F:\\home\\lissanro\\Downloads\\icmarkets4setup.exe" not supported on this installation (x86 binary)
wine: Bad EXE format for F:\home\lissanro\Downloads\icmarkets4setup.exe.
This is expected, to be honest I was surprised that the author of the article was able to run it that simple. Either Raspberry Pi comes with special version of Wine with built-in emulation (but the author did not mention this and claimed it should work on any ARM platform) or the post linked above is fake.
Here is another post which describes steps how to get x86 emulation working for Wine, this post is Raspberry Pi specific but it can be used as reference to achieve something similar on Jetson Nano:
It is not going to be easy though. To make things more complicated, MetaTrader 5 is usually offered as x86_64 executable, so x86 emulation is not going to be enough.
