Quote from a529612:
Do you usually pay up to get filled, say you put in a limit to buy open @ 4 but the ask is 4.1? Now the ask has moved up to 4.5 and looks like I missed an opportunity by being stingy on the 0.1. Is it a big no to chase options like that?

I will never place an order to buy orders at open, The price will not be right. Should give some time to establish stable option price first.
I's place order at mid-price & watch the stock & option time & sales to decide if I want to move my price. Thinkorswim strongly suggests NEVER chase, the entry price has to be right to have any edge.
