A pile of large option contracts rolling off at 14.00 GMT today 22 May

Further to my regular daily post and numerous references in others I should highlight today's expiries making an impact before I head away for the day.

GBPUSD contracts have already been attacked and defended twice while I'd expect the EURUSD expiries at 1.1225 and 1.1250 to stem further rallies, until later at least. USDJPY advances seemingly stemmed by the 111.40-50 contracts

Remember that these are "vanilla" options so still in play right up to expiry at 14.00 GMT on the day even if breached in the meantime, unlike barrier options which cease to be once hit. The actual amounts can change right up to expiry.
