Boofy, the one drawback with PRT is its inability to save different drawings of the same chart. It just won't do it. The way around it is to use different timeframes for your different lines and disable the "lines displayed on inferior time units" in the options. So your drawings on a weekly chart won't appear on the daily chart. You have the option of charting 2 days or even 3 or 4 with different lines to the standard daily.
Hubb Investor is great for saving different charts of the same stock but lacks some key features such as stochastics and fibs.
