A broker is not reliable because of bonus, it?s reliable because of service and that?s one reason why I go for OctaFX, it?s one of the best there is and have excellent set of conditions and features which include having low spreads from 0. 2 pips while there is also smooth trading platform in cTrader, it?s awesome with been develop for ECN trading and have no issues like slippage, re quote or delay, so it all helps me working nicely and that?s what I call them reliable!
