Thanks Bob, I'll send an e-mail to stockcharts now. My two year AMAT chart was different from the one posted by chichi2. I used all trend following indicators , ADX, OBV, A/D and MACD - Histogram. The ADX looked very different, probably due to the difference in time frame. So let me contact SC and we will get this issue resolved soon, I hope. To be a team we need to look at the same data, obviously.
