Meaning
This clause looks boring until it becomes the only thing that matters. Translation: spreads can widen materially without warning, especially during low liquidity or volatility shocks.
Why it exists
Spread is the price of immediacy. When liquidity providers pull quotes, the remaining quotes are worse. Brokers also widen to protect against adverse selection and upstream costs.
How it hurts
- Widened spreads can stop you out even if price ‘didn’t move.’
- Spread blowouts effectively tighten stops and increase dollar risk.
- High leverage + spread expansion is a common path to forced liquidation.
How to respond
- Use a spread gate: if spread exceeds your threshold, reduce size or skip.
- Avoid rollover/Sunday open and major releases if you trade tight stops.
- Size so a temporary spread blowout is annoying, not fatal.
Red flag
If spreads are routinely wide during normally liquid sessions, your broker may be over-marking or has thin upstream liquidity.
Notes
Plain English: the broker can quote wider prices (or receive wider prices from liquidity providers) during uncertainty. This is normal market behavior, but it changes your trade economics.
Why it matters: if you trade the same size with the same stop when spreads widen, your effective R multiple collapses and stop-outs increase.
Execution reality: your stop is executed off bid/ask, not your mid-price chart. Always think in bid/ask when sizing risk.
