Macro event open-gap guardrails checklist
Create a fixed sequence for the first 10 minutes after major macro prints so trades are sized and adjusted only when spread and depth are still valid
Direct answer
Open-gap guardrails are the fixed pause, size, and hedge checks used during the first minutes after a macro release. They keep a correct directional idea from becoming a bad fill by requiring the spread, executable depth, and hedge quality to remain inside limits before any new risk is added.
Set the first-print command chain before the event
For every macro release you want to trade through, define these in advance:
- the open-print window you will treat as invalid, such as the first 10 minutes after the timestamp
- the maximum entry delay before entering the first leg
- the maximum spread shock that still allows action
- the minimum executable depth for each leg
Write these in one place and use the same order every time:
- Snapshot depth
- Check spread
- Confirm hedge quality
- Decide whether to pause, reduce, or re-anchor
If any of those fail, the first decision is not to enter; it is to pause.
Decide gap rules by instrument profile
Your open-gap plan should be separate for each strategy type.
For near-the-money directional options
For spreads
For delta-hedged positions
- allow a wider spread than for OTM tails
- block entries if spread shock exceeds the pre-set threshold within 2 snapshots
- require one additional fill-quality print before position size increases
- both legs must pass spread and depth checks before entry
- if one leg is stale, treat both legs as non-tradable until both recover
- never reopen one leg alone
- recheck hedge leg liquidity first
- reject entries where hedge-leg fill probability is below target
- only add risk after hedge and thesis both clear
Run a structured 10-minute triage loop
The key is consistency, not speed.
For 10 minutes after the event, repeat at 30-second intervals:
- update spread and depth snapshot
- compare against pre-defined guardrail levels
- apply only one action per cycle (pause, reduce, or close)
- log the trigger reason and timestamp
If the spread keeps widening and depth keeps shrinking, keep the position under reduced risk and do not scale up inside the same gap window.
Re-open only after a clean green check
Only resume discretionary entry when all are true:
If one condition fails, keep to your reduced posture and wait for the next planned re-check.
Link the pattern with your other event guides:
- spread is within pre-set range for that chain
- depth supports planned size in normal fill cadence
- hedge leg re-check passed
- governance allows position changes after the recovery timestamp

Common questions
Can I trade through the first macro print?
Yes, but only with predefined limits. If your checklist requires a manual override, document the override and review after the event.
What if no entry opportunities appear after opening?
That is often a better outcome than forcing scale inside a dislocated market. A paused plan is a valid outcome.
Is this checklist for every event?
Use it for FOMC, CPI, and macro events with discontinuous information. For low-impact releases, use a lighter sequence with looser spread and depth thresholds.
