1.3180 expires may be the culprit behind the swift slide below 1.3210 support and ultimately as low as 1.3187.

You don’t often see a move that sharp tied to a strike that far away. I can only guess someone was long a EUR call struck at 1.3180 and wanted to book a quick profit. A large UK clearing bank led the sales, trades say.

1.3210/15 should provide some resistance on rebounds near-term.

Stops at 1.3180 are noted, traders say.
