I watch the RSI, The MACD and mainly the williams%. These are the 3 main indicators I watch on a chart. I look at other stuff but I think the williams% is probably the first one I start with.
Check this CSPL chart out Funstick. I recently started using this and like it alot. Look for a channel setup w/ the Full Sto bottomed below 20 and the Wm% below 80. All the indicators play a roll to confirm a bottom.
