01 · Overview
What is Marketlens?
Marketlens provides tick-level L2 history, replay, a Python backtesting SDK, structured analytics, bulk data, and MCP access. Best for: Quant researchers and bot builders testing strategies against queue priority, latency, depth, fees, and slippage. Less suitable for: Casual users who only need current prices or a no-code trading interface. Key limitations: Coverage follows supported product families and volume thresholds. Backtests remain simulations and cannot guarantee live fills or profitability.
