Add Alert to Indicator Similar to MacD -- A second order adding entries and stoploss, trailstop

I am interested in 2 orders:

1)  I have an free indicator called Mac D Mirror. I wish to have an alert added to warn me when the red line crosses the blue line in either direction. Or it can be when the red line cross the zero line in either direction.

2) I am also interested in having a version of this EA that can make entries when a crossing occurs, dependent on conditions set through user inputs. Add stoploss and trailstop:

   -- How much rise or drop in pips after a crossing before entry is made

   -- A minimum height or low of the red line in the previous range before crossing

           Add an input for the period of time or number of bars back in which this range is measured.

   -- Stoploss in pips

   -- Trailstop in pips

   -- Number of pips in profit when trailstop is triggered

This is for the Metatrader 4 platform.
