MACD Trend Following Backtest: Bar-Close Signals vs Next-Bar Execution

MACD signal-line crosses are confirmed at bar close. Trend rules hold for a long time, so execution differences matter less per trade — but not zero.

Short answer

A MACD trend rule (long when MACD closes above its signal line, exit on the reverse cross) has fewer, longer trades. Execution model differences per trade are small relative to trend gains, but intrabar crosses that reverse still add whipsaw trades. Compare intrabar, close and next-open execution; the main gain from realistic modelling is removing un-crossed intrabar signals.

Where the difference comes from

With longer holds, the per-trade cost of a few basis points of execution is small; the bigger distortion is the extra whipsaw trades intrabar evaluation creates.
