Max/Min Rule Help  [SOLVED]

I am looking to produce a trading rule and need some help with the code.

I would like to have:
Running Maximum of the previous 14 periods
Running Minimum of the previous 14 periods

I would like to compare these running min and max to the current close and the trading rules follow:

Sell if Current Close > Running Max
Buy if Current Close < Running Min
