I have been trading in Olymp Trade for 1 year and I have not to complain! It is a really good platform, very easy to understand the graph and its interface. Also, the depoists are very fast and there are many options for that.
The demo account is another great option for people that are starting and do not know w how to trade.
When I started I coul test my strategies trough the demo account and it really helped me.
All my withdrawls aslo happen fast. The support is excellent and hepful.
