sounds

Investor/RT can handle a variety of sound file types including .wav, .mp3, and .m4a.  To review and preview the current sounds available, visit File > Preferences > Sounds.  These sounds may be used in a variety of contexts within Investor/RT including Alarms, Signal Actions within indicators (Reference Lines, Signal Markers, TimeAndSales, etc) and even custom quotepage column rules. 

Is it possible to set voice alarms or sound alarms with Investor/RT (wav file)?

Yes. One example could be "News in 5 minutes". This sound could run on the schedule before news announcements each day. Or you might create a sound that says "CCI Buy Signal" and use it when the a CCI-based long signal fires.

You can use any voice record software to create sounds files. If you already have the wav files, then go to step 3 below.
