Have inverse ETFs made internals like $TRIN $add $vold obsolete? A guy named shadowtrader (who is a contributing member on elitetrader) mentioned this in a video that he made. Here is the video: http://www.shadowtrader.net/videos/bonus_internals_08.html and he discusses why from 2:55 through 3:55. He says in the video that he stopped using the $TRIN because "too many inverse ETFs with volume flowing into them makes the TRIN seem more bullish than it really is". What I don't understand is wouldn't that same reason make the other two internals that he was using (NYSE Adv Issues - Dec Issues) and (NYSE Uvol - Dvol) also be heavily affected? Just trying to understand. Thanks for your replies.
