Meaning
This clause looks boring until it becomes the only thing that matters. Translation: the broker may reject, re-quote, or re-price orders when the market is moving fast or when liquidity is thin.
Why it exists
Some execution models allow ‘last look’ or risk checks to prevent filling you at a stale price. In stressed conditions, the broker prioritizes staying solvent over giving perfect fills.
How it hurts
- Asymmetric slippage (worse fills more common than better fills).
- Missed exits in fast moves.
- Partial fills creating unexpected exposure.
How to respond
- Trade smaller in fast tape. Size is the only universal adapter.
- Avoid strategies that require tick-perfect entries/exits around releases.
- Log rejects and re-quotes; if persistent outside news windows, reconsider venue fit.
Red flag
Frequent rejects during normal liquidity can indicate misalignment between your style and the broker’s execution model.
Notes
Operational reality
Partial fills are normal. The risk is when you assume you’re flat and you’re not.
Execution rule: if you feel urgency, reduce size. Urgency is expensive.
