NWZ Update-

Price again dipped lower during the session, before recovering to close a pip higher than the previous bar, and level with the lows of the recent higher volume bar (which it really needs to get back inline with....at the worst....as it may offer resistance in the future otherwise).   It didn't really find low volume as it dipped lower, but it does suggest an element of support came in and bought the supply that was drawn out. Don't be surprised if price repeats the procedure in the near future (Friday ??), to see if supply is low the next time around.
This type of bar would probably be classed as a 'basic test' which can also be seen as a higher volume 'mini shakeout bar' - which is only a minor sign of strength at best.  Just remember that (generally) in a downtrend, any minor signs of strength need to be discounted, and so far the downtrend is winning.......easily.......
