If your still not out you may have to change your

If your still not out you may have to change your order to a market, hard to get a fill on the sell side with a limit especially if it's for a lot of shares, the way it works when your trading on the greys or a lower tier pink sheet stock.

If it starts diving you won't get out period with that big volume. I know, seems like with all the volume it would be easier but again, doesn't work like that on these lower exchanges, old boy looking out for old boy!
