The M1 ATR buffer idea works in theory
manually adjusting limit caps seconds before NFP is a nightmare.
Missing 30-40% of explosive winning moves just to save 3 pips of slippage completely destroys your strategy's expected value over a 100-trade sample size. I stopped using Stop-Limit orders on news releases for this exact reason.
If you're consistently getting 10–15 pips of negative slippage on standard Stop-Market orders, the issue isn't your order type it's your execution pipeline. I switched over to Goldmann to test their direct market access (DMA) setup during CPI events. Because their execution bypasses dealing desk queues and routes directly to interbank liquidity, market order fills on EUR/USD rarely slide more than 2–3 pips even during peak volatility. Plus, having hard-coded Stop-Outs (at 30%) and pre-trade margin calculators right in the order ticket takes the stress out of managing downside risk.
Bottom line: use Stop-Market to guarantee your fill, but trade on a direct routing platform that won't punish your order book during liquidity gaps.
Promises of zero slippage during high-impact events like NFP are a clear red flag for an internal B-Book simulator, as true direct market access (DMA/STP) cannot physically bypass interbank liquidity gaps and spread widening.
