yep its like a waiting line. even if you put it over the weekend you are going to be ahead of the next guy...i do this sometimes when i think i wont be able to buy/sell because availability/demand might be low. look what happened on tuesday..i woke up @ 9:00am not expecting anything.woke up to a RS! it was already gapping down but i started putting my orders way under the bid 30 minutes ahead...MILLIONS of hares traded ont he way down and i couldnt rid of 43k! stupid spng releasing rs 630 in the morning so early causes a line to exit be formed extra early (hence the huge gap down)
