Actually, I did post a chart right before the stock dropped. I think I may have also mention that we need the SP to go down so that the MACD would cross down in order to set up for a positive cross. Of course other indicators would need to play out in addition.
There are a lot of traders who are watching this chart and hundreds of other penny stocks. I usually never chart any subpennys, but everything else is fair game. Not sure who told you charts don't work on penny stock.
