This is probably really stupid but I would rather know for sure than not. So the orderbook displays currently open orders, so "Buy" orders listed there are open buy's from other users, to whom I could sell contracts? Or do I have it backwards.
Also, so given that a Buy order is listed there, ex. 250 contracts with a price of 660. Given that I understand my above question correctly and that is in fact an order I can sell to, would I have to sell 250 contracts at 660 to match up with that one? Or if I only sold 150, would it execute for me and only partially execute the other users order, leaving him or her with an open order of 100 contracts at 660?
Thanks in advance guys!
Partial execution is fully supported. Minimum quantity to buy or sell is 1 contract (= $10).
