Thanks for reviewing us. As you may know, we have started the process to transition to a new data provider that provides European data too. We're working around the clock to implement that!

Thanks for sharing your love for our platform, Denny!
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.

It would make me really happy if you can add European stocks (at least the blue chip ones). Keep up the good work!
