Add Alerts to Stochastic Momentum Index (SMI)

Hello,  :)

Alerts added to this SMI indicator (linked below) would be awesome.
Perhaps 3 columns (one for Sound, one for Popup, one for Email) of checkboxes that can turn either Alert and Alert Method On/Off is a possibility?

Main Alerts to add.
Buy - When the SMI crosses from below the Buy line to above the Buy line
Sell - When the SMI crosses from above the Sell line to below the Sell line

Secondary Alerts to add.
Buy - When the SMI crosses from below the Sell line to above the Sell line
Sell - When the SMI crosses from above the Buy line to below the Buy line

Other Alerts to consider adding.
Buy - When the SMI crosses from below the EMA to above the EMA
Sell - When the SMI crosses from above the EMA to below the EMA
(the EMA I am referring to is in the SMI window, not one put on the main chart)
