Removed the Alert output.
To create on Sinewave + Momentum OK signals you now have a specified alert.
On the Alert window, select PRO Momentum as input, then among the trigger conditions, you should find "BULL OK" and "BEAR OK" on top of the list. These two conditions will trigger when both the Momentum & Sinewave are displaying OK signals to buy. Simply select the desired trigger option for the alert and you're done !
