QuantConnectReviews of quantconnect.com

The software is full of bugs and the support is terrible. The paid version offers no real advantages.

Sure the system is great, but my experience was bad with the Founder & CEO Jared However he offered me free trial to test my system and I appreciated that so much, after we discussed the pricing he deleted my account and replied "I dont think we can service your account sorry. We cannot meet your expectations for the cost youre asking." Even if you didnt accept my pricing request, why you deleted my account? I didnt find any reason to do it and it was not professional

Oh my lord I am too busy during day to write review but my experience with QuantConnect is sooo BAD I am compelled to write a bad review. Their website is extremely poorly designed and they should fire their UI designer immediately or maybe pay more for them to do a better job. I feel like I need a manual just to navigate the ugly and complex site. Their user documentation is abysmaI and their design of the web-based IDE to write your algo script is slow and buggy as it freezes alot and you have to refresh the page. Only their LEAN command line option is useful but its still a pain to setup and learn but still has bugs like local backtesting differs from the cloud. I tried them out for a week before committing to pay for a "researcher license" to use the backtest quicker. I wanted to then buy a live testing node simply to see if their live prices work but when you try to order this from their website it automatically buys you a bundle with a massive support fee included which is not what I need. I only found this out after they email me the invoice to my disgust at a huge extra fee. I asked for a refund of this extra since I only wanted the live node not any extra support but they refuse. Extremely bad service so I'm warning others to be careful they will force you to pay extras you don't need when you order from the site.
