QuantConnectReviews of quantconnect.com

QuantConnect continues to provide value and innovate in the algorithmic trading space and it doesn't appear to be abating anytime soon.

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

Very powerful and convenient service. Good price/quality ratio

QuantConnect has a great platform for developing trading strategies. My development environment is VSCode and Claude Code. I am a long time quant, short time QC user but I learn something meaningful every day and get more productive every day. Peer user support and QC sponsored support is great. 100%

Quantconnect offers a seamless environment to test your code, backtest for results, and deploy to production. They also have an active community with a lot of great ideas and a willingness to share. Some downsides are that it takes some commitment to learn the platform. It's also a little pricey compared to doing it yourself. But in the end you pay for convenience as the only comparable alternative is a do-it yourself alternative of writing code on your own, integrating with a broker, and deploying on AWS. This alternative still has costs - particularly your time spent. I fully endorse Quantconnect, especially to those that want to spend more time earning money over managing a code base and deployment infrastructure.

Overall great platform. Great platform, I have been using it for a while now and it really is spectacular, so thanks for the platform. So why am I not giving it 5 stars? Well, as a EU citizen, I can't create algorithms that trades ETFs. For regulatory reasons, I cannot trade ETFs like QQQ, because it doesn't have a KID (nothing to do with QuantConnect). However, QuantConnect has no integrations with any EU exchanges! That means that all of the EU alternatives are blocked, and this is a QuantConnect decision. So even though I can trade the EU ETFs through my broker, and QuantConnect has an integration to the broker, QuantConnect isn't allowing the trade with the EU alternative. Furthermore, since there isn't a single integration with any EU exchanges, I'm blocked from trading ETFs altogether. Just an FYI for any Europeans considering this platform. QuantConnect suggests exchanging the ETF with the corrosponding CFD. This, however, is only feasible for intraday strategies, not for rebalancing strategies that works on higher timeframes since CFDs come with overnight fees from the brokers, quickly adding up. Again, great platform, but as a EU citizen, you're just not prioritized, and you won't be any time soon.

Good application go all
