Adding more features to an existing indicator

i would  like to add some more entry filters to the hma histo 1.01 for entry. first the signal from the hma histo 1.01 has to match the trend2 indictor . if the histro gives a sell the trend2 has to be red . if the histro gives a buy signal the trend2 indictor has to be green and the last conifirmation is that for a buy it has to close under the center line on the iq fasttma line for a sell it has to close above the tma line

the setting for the hma histo are

hma period to use=17

price to use=average (high+low+open+close)/4

hma speed=1.8

make all setting adjustable
