When selecting a time period from the past and looking at the market timing chart or any stock chart it would be nice if technical indicators are in sync with the past time period that is currently selected.

Example: Open market timing graph and the current date is 11-22-11. Add support and resistance with the default settings. Now change the date to show 12-27-10 – 03-09-11. It would be nice if support and resistance would update to show the support and resistance lines from this past date. Then I could step forward each candle seeing how the support and resistance lines draw on the screen. This would be really great for intraday charts also to do testing when the market is closed.
