Co to gap risk
Gap risk weekend = forex market closes Friday 22:00 GMT, reopens Sunday 22:00. 48h zamknięty. Weekend events = price gap między Friday close i Sunday open.
Historic weekend gaps
„Brexit referendum 23 czerwca 2016: GBP/USD gap -1600 pip. SNB removal floor 15 stycznia 2015: USD/CHF -3000 pip. War events similar potential. Weekend = niewidzialne ryzyko."
Why SL fails
SL = order „close pozycja gdy cena hit X." Ale weekend market closed. Sunday open:
- Friday close 1.0850 long EUR/USD
- SL set 1.0820 (30 pip planned)
- Weekend event: war announcement
- Sunday open 1.0700 (gap -150 pip)
- SL fills @ first available = 1.0700
- Actual loss -150 pip vs -30 planned
4 mitigation strategies
Strategy 1 — Close Friday
Top simple: close all positions Friday before 22:00 GMT. Re-enter Monday post-open. Eliminates gap risk completely. Cost: spread + missed trends.
Strategy 2 — Reduce size
Hold positions weekend ale 50% normal size. Gap risk -50%. Manageable. Trade-off: missed gain potential.
Strategy 3 — Hedge opposite pair
Long EUR/USD + short EUR/GBP partial hedge. Gap moves correlated. Reduces net exposure. Complex.
Strategy 4 — Options buy
Buy OTM put options weekend hedge. Cost: premium 0.5-1% account. Insurance against catastrophic gap.
