GBHighly recommended They make a great product and offer a good service. They are responsive. It takes time to learn their tools and how to navigate their website which is no different than any other comparable site except that you are doing far less coding from scratch and more actual thinking and developing trading models.

FRGreat Tool Great Tool, great team, great support. I am a very satisfied user for 9 years. I have spent countless hours on it. Only concern: their are dependent on data providers policies. It may occasionally result in changing data or pricing. Backtest servers are much faster and more reliable than in 2 other similar platforms I have tried.
