definitely the most manipulated, but unfortunately it often works to push the SP in the direction of the big boys doing the attempted manipulation, so there's no way I'd call it the most unreliable indicator for those wanting to get in and out for a day trade, I think to totally disregard the buy/sell depth would not be in the best interest of a day-trader who hasn't sat there and had time to analyse what's going on in regards to are there algo's at work, are there buy/sells getting pulled when they are about to be hit, etc,,,,if you are in for a ST-LT trade and have done your homework on the FA then that's a different story
