EMA Crossover Backtest: Bar-Close Signals vs Next-Bar Execution

An EMA crossover signal is known only when the bar closes. Filling at that close, instead of the next open, flatters results in proportion to how far the open gaps.

Short answer

In an EMA crossover backtest, the cross is confirmed at bar close; a realistic fill is the next bar's open (plus slippage). Filling at the signal bar's close assumes you traded at a price that only became known at that instant, and filling at an intrabar cross assumes the cross held. On crypto, the next open usually equals the prior close on continuous markets, but slippage, spread and latency still apply; on fast bars the difference compounds over many trades. Compare the three models on identical signals.

Where the difference comes from

Intrabar fills count crosses that later un-cross and fill at better prices; close fills skip spread and latency. On continuous crypto markets the next open is usually near the prior close, so most of the gap comes from slippage, spread and un-crossed signals.
