Of course, both the mobile and web-platform have certain specific features, but their functions are basically the same. You merely have to consider that mobile phones have different management principles, plus the screen is way smaller, thats why the platform looks overall different. However, all the things you do on the web-platform are easily performed on the mobile one.
Probably the most important difference between the PC and mobile platforms that Ive noticed is the limited number of indicators used simultaneously. For instance, the mobile platform allows maximum 5. But who actually uses more than 5 indicators at once?:) Personally for me thats quite enough.
So Im pretty fine with the mobile platform. In fact, I trade on it more often than on PC. But in my opinion, both platforms are equally good - thats just a matter of preference.
