Atty Execution Reality
Point it at any level, such as the prior day high, the overnight low, or any other indicator's plot, and it tells you how often price traded to that level versus gapping straight past it, what the slippage was, and whether the move you are playing for is bigger than the round-turn cost.
It recovers the effective spread from open, high, low and close alone, with no tick data and no order book, using a method from the peer-reviewed literature that we validated against a synthetic bid-ask bounce with a known answer. On ES one-minute bars it reads 0.89 ticks, which matches the market: ES is one tick wide nearly all the time.
