"Be flat 15 minutes before NFP, CPI and FOMC" is common advice. Some traders treat it as non-negotiable, others find it too restrictive.
Arguments for the rule:
- Spreads start widening in the minutes before major releases.
- Pre-release positioning creates erratic moves.
- No chance of being caught with a position in the release.
- Simplicity: no judgment calls under pressure.
Arguments against:
- 15 minutes is arbitrary. Spreads may not widen until 1–2 minutes before.
- On quiet days, the pre-release period can have clean, small-range trading.
- If your trade is well in profit with a protective stop, the risk is limited.
Possible refinements:
- Shorten to 5 minutes for medium-tier data.
- Allow holding through with a stop at breakeven or better.
- Require flat for CPI and NFP specifically, while FOMC requires flat from 30 minutes before the statement.
Whatever version you choose, the key is to decide it in advance and not change it on the day based on how you feel about the trade.
What's your rule for being flat before major US data? Strict 15, or something different?

Re: Flat 15 minutes before Tier 1 US data: a rule worth keeping?
Sessions begin with a rush. London opens, volume jumps, price moves. The urge to trade is at its strongest, precisely when conditions are least predictable.
Many scalpers overtrade in the opening minutes. Spreads are still settling, early moves are unreliable, and the first impulse often reverses. Yet the pull is strong, partly because of the accumulated wait. Hours of waiting end, and the need to act builds up.
Logs of overtrading show a clear shape: a cluster of trades in the first quarter hour, most of them marginal, with below-average results. The rest of the session has fewer trades and better quality.
The fix is structural. A rule such as "no trades until 15 minutes after the open", enforced by a timer or a simple checklist, removes the temptation. Watching and marking levels in that period, instead of trading, turns the energy into preparation.
It doesn't need to be forever. Testing the rule for a month and comparing the results shows whether the early minutes were worth trading.
How many trades happen in the first 15 minutes of a session, and how do they compare with the rest?
