Intentions to be different, I assume. Nowadays the market is full of similar brokers which don't even strive to be different.
Tredero in this regards sticks out, cause the company has managed to develop and release its own application that is quite optimized and full of instruments.
Other than that, look at the Trading Central feature. Awesome way to save your time and discover new ideas which will be definitely helpful during the analysis.

It seems to me that the fact Tredero broker has managed to devise and embed its own solution already deserve credits. It's easy to draw side software, I ain't know exactly how this process arranged, perhaps, there's a kind of agreement, but it has nothing to do with developing own platform.
Tredero app, according to my experience is an optimized software for trading that is packed with all modern instruments.
