Independent mentions

  • QuantConnect Review: What LEAN Actually Runs — FullStack Alpha — LEAN is a serious engine and QuantConnect gives retail traders something close to institutional research infrastructure for a few hundred dollars a month. That is the case for it, and it is a strong one. The case against comes from r/algotrading, where the complaints are unusually specific rather than vague: earnings date data wrong roughly three quarters of the time, intraday errors on heavily traded tickers, indicators returning identical values across different timeframes, and backtests hangi
