Scanner with alerts

Hi,

I need a realtime scanner that monitor all the available stocks and when conditions are met, it displays them on the screen and send alerts by push and e-mail.

Conditions

1-) RVOL (Relative Volume)

For instance if XVZ symbol trades on average 3 Mio shares till 12am and now it is trading 12 Mio at 12 am the RVOL is 4. (please calculate this average volume based on the last X days defined by me on a parameter).

The scanner monitors in real time based on the volume traded during the day, if during this time volume is >= a defined RVOL determined by me it must send and alert and be displayed on the screen.

2-) Price Spike

This is another alert. If there there is a price spike (variation) higher/lower than X% (parameter defined by me) to send an alert and also be displayed on the screen.

Thanks
