Dear fellow metastock users,

I'm pretty new to programming and metastock so mind me for this noobish question. I'm trying to write a system which exits a trade based on the high or low price one day prior to the entry of the trade. how should i go about it.

For eg,
Long :=c>mov(c,10,e)
short := c<mov(c,10,e)

Thanks for the trouble.
