hello, to use the indicator 3c_JMoving Avereges which is color magenta and green, what indicator or files are necessary ?

i downloaded it from the front page , but there is too much indicators with it. 20 plus 3cj indicators as well as 20+ other indicators. I deleted all other indicators except the 3c_JMoving Avereges but MT4 cant use it anymore.

Reason i want to delete the unnecessary one because my MT4 expert is too full already.
