P.S. If MyFxBook just connects to an account, download the history, exporting it via the MT4 client, I do not see any hacking, back engineering etc.
Yes, it can be done also that way. And there's one product for that I know: mt4 java api jfx. And its reasonably priced!
But that doesn't prevent MetaQuotes from blocking you if you open 100's of connections simultaneously to a single broker in rapid succession to poll all accounts there.
It just depends what kind of algorithm they use for the blocking. And have they changed the protocol slightly to detect genuine clients from hacked clients.
And remember that Myfxbook is not the only service that has run into these connection problems lately.
Its all about money, like trading 😁
Being Bearish or Bullish Makes No Difference
