Sorry, should have been clearer, should it not open up 8-10% higher, then start tracking futures from there? Ie. open 10% higher to account for 4% drop in DOW on Friday, then current as futures down 1.5%, overall should be 11-14% higher? At least that's what I feel was happening early last week when it dropped 20% at open on ?Tuesday, then stayed around there despite futures moving down

Making me feel like a mug is all, with risk/reward not exactly matching up even when I've positioned what I thought was correctly. Makes it easy to complain about market makers but would rather know that everything is right and I'm wrong
