I opened $COST VERTICAL 240301 CALL 710.0/CALL 735.0$  ,COST: Sold bear call spread on Costco at 0.4 delta as I’m bearish on Costco after hitting new all time high around $705. The spread is wide to maximise my profit zone therefore the maximum loss is also high at $1900 per contract should the trade goes against me. Will start to lose money if Costco goes above $716 so I’ll monitor closely once it creeps above the lower strike price if $710.
