The Olymp Trade mobile app is most efficient when utilized in tandem with the web-platform. In fact, the mobile platform is quite convenient when you have no access to the main one - for instance, when you're on the road or simply away from home, but still up to some trading meanwhile. However, when you're at home or at the workplace where you trade, you'd better use the web-platform - at least I find it way handier. The web-platform provides more opportunities for analysis, particularly a big number of assets for technical analysis. To sum up, you just gotta know how to use each of the platforms to the most good and when it is optimal. That way, your trading results will be more than satisfying.
