In contrast to many people who write reviews, I started trading at Olymp Trade in MT4. Before that, I simply didn't understand how to trade on their so simplified platform. So, I was delighted when the company has introduced an ECN account in MT4.
But I chose the company only by feedback. As I recall now, I read the review of a trader who criticized the platform. However, he said that he never had any problems with the withdrawal of funds here. It always was quick and easy.
