Three illustrative XAU news scenarios: a post-CPI break-and-retest entered seventy minutes after the print for around 1.8R, an NFP whipsaw that stopped out both directions with slippage, and an FOMC statement move fully reversed by the press conference.
The workable example waited for spreads to return from $3.20 to $0.35, let a post-release range form, and entered a retest at half size with a 0 stop scaled to elevated ATR.
The failures both came from being positioned inside windows where direction is unknowable and fills are unreliable, which is why the next London open is often the better trade after FOMC.
