That could work...I use TDA's custom stock trading program that I can import whatever alert sound that I want when I place my buy/sell targets. When the $$ of a stock hits my set buy alert instead of a audible bell/whistle/chime/buzzer I programmed it to scream Cramer's "BUY,BUY,BUY! Same with a sell alert that scream's 'SELL,SELL,SELL! when it hit's my target. It's just a digital wav. from his soundboard.
Just need to get a digital wav. phrase triggered instead of the beep tones in a MD like PASS/DIG or TRASH, RING, COIN etc. If it's just a audible change in freqency to produce the diff tones then it shouldn't be that hard. Of course not knowing is part of the thrill but even though it scream's GOLD it may just be a false signal same as the beep tones give.
You gave me something to think about now...Thanks!
