If I programmed a charting package like the Medved Quotetracker, except that it also had the option to alert with both visual and audible signals when a stock price crossed the path of any particular technical indicator that you were utilizing at the time, such as ema or bollinger band etc., then would you subscribe to it for the same price as Quotetracker. I think that this addition could be the handle of the "holy grail" for daytraders. All replies are greatly appreciated
