EP, you are right Barcharts is a black box system and it isn't nearly as good as your analysis. You are also right, in this market, 100% buys at Barcharts is a signal to get ready to sell. In a strong market, like we had most of 2003 in the microcaps, a stock would stay at 100% buys for weeks. However, I watch Barcharts very closley and everytime one of my stocks drops below 50% buys, it almost always goes below 0% buys very rapidly just like PDGE did.
