Scope and depth. QuantConnect covers every major asset class with tick-level history, has 40+ alternative data vendors, an open-source engine you can run locally with the LEAN CLI, and institutional live deployment. If you trade equities and options alongside crypto, or need to own the engine, QuantConnect is the serious choice.
Getting to an honest answer fast, in crypto, without being a programmer. Your AI writes the strategy, validation is free and lists every problem at once, and each backtest returns an honesty grade and an overfit verdict. Fees, funding and intrabar fills on 1-minute data are the default, not a setting to remember.
QuantConnect's Mia answers documentation questions and helps debug inside the Algorithm Lab, and Assistant Compute runs agentic research there. OptAlgo brings the lab to the assistant you already use: an MCP connector for Claude.ai, ChatGPT and Claude Code, and an API key for Codex and any terminal agent.
QuantConnect's Free plan gives unlimited backtests on a delayed node (up to 200 a day) with no live or paper trading. OptAlgo's Free plan gives 50 backtest units a month, one hosted paper strategy, 200 paper trades and 2 webhook bots with 10 live trades a month.
faq
For crypto strategies written with an AI assistant and graded for honesty, yes. For multi-asset research, tick data or a self-hosted engine, QuantConnect is the better fit.
Not directly. OptAlgo strategies are plain Python against the OptAlgo SDK (numpy and the SDK only). Your AI can usually translate the signal logic in one pass; the backtest then tells you whether it survives real crypto costs.
Every competitor cell quotes that company's own pricing or product page on the date shown under the table, and says “not stated” when their page does not say. If something changed, email [email protected] and we will update it.
Yes. OptAlgo backtests and runs strategies on your own exchange account through API keys, so nothing stops you from keeping another platform connected to the same or a different sub-account.
