Daily market-microstructure timeseries for one security

Changed on

Per-security daily lit-microstructure history (hidden/odd-lot/cancel/trade-to-order rates, average trade size, volume, deciles), ascending by date. Use limit to return only the most recent N days. SEC Market Structure (MIDAS) metrics describe how a security trades on the lit exchanges, aggregated across venues per day: hidden_volume_rate is the share of executed volume that came from non-displayed (hidden) orders - a dark-liquidity-within-lit signal; odd_lot_volume_rate, cancel_to_trade (order cancellation pressure), trade_to_order_rate (fill efficiency) and avg_trade_size round out the picture, with mcap / turnover / volatility / price deciles (1-10). Off-exchange (ATS / dark-pool) venue volume is NOT in this dataset - it covers lit exchanges only. Source: U.S. Securities and Exchange Commission.
