What Happened to Quantconnect?
6.) You cant maximize position size of spread options strategies, LEAN always assumes naked margin first and ON THE NEXT DATA FRAME - you get your reg-t margin for spreads. https://github.com/QuantConnect/Lean/issues/5693 We're running into 2 years of this issue being reported.
- Thoughts on QuantConnect?

Quantconnect - Backtest script that accepts multiple dropbox links, creates portfolio, and rebalances on predefined dates, advice?
They have nice documentation on their website for how to download/import external data, though. They even have GitHub examples that pull data from Dropbox.

What's the best platform to backtest a large amount of 1m data using a simple volume-based strategy ? TradingView provides a minimal amount of candles in the 1m chart to backtest on and I need to test it further.
