//| V2 DME 4/29/09 added Sound and Sound File option
//| restricted alert or sound playing to one bar duration
//|
//| Alerts or Sounds once per Tick for one bar when RSI passes into overbought or oversold.
//| v3 DME 5/4/09 added user option to restrict quantity of alers during one bar.
//| Note that if RSI tick by tick goes into oversold and back to non oversold and then
//| back into oversold the alert counter gets reset each time so you will hear more alerts
//| Show Alert will show text in alert text window and play default standard alert sound
//| Play sound will allow user to set a custom wav file however the text alert will not show.
