Need help with an ADX alert

Hi, all: could somebody make an alert for me (that also puts an arrow on the chart) when the following ADX set up is complete, using the attached version of the ADX indictator.

for long:
DMI+ > 20
ADX < DMI+
ADX > DMI-
DMI+ > ADX and ADXr
DMI- < 20

for short:

DMI- > 20
ADX < DMI-
ADX > DMI+
DMI- > ADX and ADXr
DMI+ < 20

the attached photo shows the point at which i'd like the alert to go off (and a dot to appear on the chart). i hope I've got everything marked out right and in the proper order. the thread this idea comes from is here: http://www.forexfactory.com/showthread.php?t=571649

thanks for any help you can offer!!!!

the 20 line is the horizontal one in the picture; forgot to label it.
