Guess I am a little surprised that you would presume that I don't know that TNA exists, but that is okay. You could have asked why I don't use TNA.
Very interesting opinion that you gave about the difference between using IWM and TNA and being able to see the support and resistance points better with TNA. Below I posted a 1min chart for today of both IWM and TNA. I left off the scale on the right or of course that would give away the secret of which one was which. I would assume that you can tell me which one is IWM and which one is TNA. I promise this is not a trick, one really is IWM and the other is TNA.
