Check out this site for all the hidden trades. Wondered why a lot of mine did not show up. NTY are traded on the PLUS market which is where MMs trade for themselves. News to me that they could this but I had my suspicions. You will see additional buys here. When I had to sell some a few months ago they did not show up, MMs were buying them and keeping for their own use. Good sign IMHO. Also when I bought back they did not show. I don't think you will get a correct view by looking at normal trades.
Will be checking this site regularly now. There were more buys than reported. This is why you see ticks up and down with no trades. Will report here if any unusual trades.
Good luck all I know I have been bullish for a long time but the turnaround obviously took a bit longer than expected. I still expect a sharp movement v soon but this will depend on volume.
