Quote from bmonte:
For Vista and R/R:
Here is my screen shot of Str/Squ on Quotetracker. The left and middle windows are the setup in QT (they get covered up with my ES, YM, and S/S charts during the trading day) . The window on the right is the S/S chart itself.
Editing the $Cash (offset) value as shown in the left hand (Portfolio/edit portfolio) window will center Str/Squ around zero. The offset tends to drift somewhat during the trading day so you will have to observe the average Str/Squ bars over the last 10 or so minutes and adjust the offset accordingly.
Remember, with S/S, only the movement of the last bar is useful for anticipating market movement near points of change, so a wide chart of past S/S is not useful.
