I have not heard of any such sites. It would be to hard to track.... you throw in that the majority of pink traders ~~ day trade~~ then you add flippers, nervous newbies and shorts on top.... it would be virtually impossible for ALL brokers nationaly and internationaly to track and submit the daily activity for thousands of tickers sell price ....
then on top of that, pinks dont usually get a set GTC on a sale.... you watch the run and act accordingly.....
I will ask around though! (but IMO and experience I have not seen any, so no!)
(Trust ME, I would not lie to YOU!!!) ;-0)
