Maybe you should call fxpro support and they can help you with the platform problems
I think that the spreads at LMAX are great but they have a very high minimum deposit and I dont like their in-house platform.
I have never had any issues with the cTrader platform at FXPro. It is one of the best platforms I have ever used, I also use the cTrader at IC Markets for my algo trading. I have never tried it at divisa so I can not comment.
