Now that ISLD is soon to be under the control of Supermontage, sitting on the bid is gonna be tough, since the MMs will get all the orders by shaving our prices to death (preventing us from executing) and benefitting from price priority... currently ISLD is a market unto itself, but it seems that soon ISLD traders will not be able trade with eachother... I hope I am mistaken, but this seems like its gonna be back to the bad old days of buy ask, sell bid... which is fine for liquid stocks, but which will be a killer for trading thinner stocks (since the spreads can be brutal on those)...
