I have made a handful number of trades in options. So may be my question is pretty stupid. However I tried to open position where some of orders had same strike as previously held position in opposite direction. I was kinda confident if there are types of orders as Buy To Open and Buy To Close... so when I want to open a position I send BTO and if I want to close I shall use Buy To Close explicitely. But half of my spread got closed (the most profitable wing of course) and now I got bunch of useless randomly arranged spreads which will be bugger to close with profit.... My question - is it normal thing to be in the options world and I am just being ignorant and picky? Or my broker sucks? (BTW - when I asked support - where can I see T&C about such a stupid behaviour he folded and run away).
