Looking for 50 point reversal system

[LJK]

I was woundering if there is any code that exists for a system I would like to try.

I would like to look for a 150 pint move in the YM #F from a prior low and then go long. when the YM #F moves back 150 points from the last high go short.

This would be a simple reversal system I would like to test.

Code would be great

Thaks in advance
