Added Alert options and extra feature

Hi all. I added the option of switching alerts on / off as well as the alert to appear AFTER a certain number of candles. This is so as I noticed that at time the MA crossover appear and retraces and then reappear within 1 candle session. Now you can decide on that session by using XBak. Decide on the alert after "XBak" number of candles after a MA crossover OR leave it at 0.

Place in on your charts and change values to see the effects.

Finally MAKE SURE YOU ALSO PLACE THE 3-level-zz-semafor LD indicator into your Indicators folders. These will not work without that AND you need not do anything here with it input values.

Regards
