MT4

It’s good that the broker has chosen MT4 as their main and only trading platform. Nowadays brokers prefer MT5 maybe because it’s more technologically modern I have no clue. However I’ve been trading with MT4 since the beginning and it’s the only trading platform I want to trade on.

Spreads of the broker though could be lower. But the absence of commission can compensate for high spreads a little bit. Overall is a good broker with its own style.
