I placed a buy order at .0007; sat there for over an hour without filling. So I changed the limit price to .0008--it filled *immediately*. I don't know what this means but it usually took longer to fill an order at the ASK for my previous orders over the last couple of weeks. I hope I didn't make a wrong decision to buy--we'll see.
Everthing I state is my own opinion (IMO). Do not make any trading decisions based on anything I state.
