Does anyone know if there is any software that will record the entire trading day as it appears in the level 2 quotes? For instance, I want to record the SPY's and QQQQ's and study their price action after the market close, so I can continue to trade what I trade now intraday w/o having to put that aside to watch/trade the SPY's and QQQQ's. Does this software exist, and if so, anyone using it? Thanks.
