DislikedPrice moves because there are sellers and buyers at different levels. But if no one was on the other side, than the transaction would not be made. But still for every transaction there is an equal amount. Can't have sellers of 3 contracts and buyer of one. that would leave 2 contracts not fullfilled.Ignored
lets suppose there are three sellers at 1 and one buyer at 1 - you have 50:50 (two sellers have pending orders) but you have 75:25 if you consider the whole market.
and now - lets suppose there is a "market maker" who sees the two sell orders and purchases those from the seller. But there are not buy orders - its just the market maker who fulfills the sell orders - suddenly the sentimet is 75:25.
not really sure if the reality works the same, but thats the explanation i gave myself
