The first minute of a session is a bad place for tight stops

[Amanhasnoname]

Session opens look like opportunity: a burst of range, fast candles, obvious direction. For a scalper running 3 to 5 pip stops, the first minute is often where the account loses to noise.

Three things happen together. Spread widens briefly as liquidity providers reprice. Tick-to-tick volatility jumps, so a price that will end the minute 2 pips higher might trade 4 pips lower first. And execution gets less predictable, with stops filling a pip or more beyond their level.

Picture a London open long with a 4 pip stop and a 0.8 pip spread that momentarily becomes 2. The stop is effectively 2.8 pips from the bid when the ask spikes, and the usual wick that would have been absorbed now takes the position out. Five minutes later price is exactly where the idea expected. The idea was fine, the stop was sized for a different market.

Two ways to handle it:

- Wait until the first five-minute candle has closed, then trade from the second one
- Keep the early entry but size the stop from the opening range, not from a fixed pip number

A quick test is to compare stop-out rates for entries at minute one versus minute ten of the same session.

How long after the open do you wait before the market feels tradeable with a fixed 4 pip stop?
