Joe Duffy's S & R - 3x5ATR

I do, however, have one more question. I recently came across a technique published in Futures Magazine used by Joe Duffy for identifying S&R levels. He calls the indicator the 3x5ATR. I'm sure this can be created/reproduced in Ensign, but I'm having a tough go of it. He defines the construction below:

1. Add up the true ranges for the last five days and divide by five. This is the 5ATR.

2. Calculate a three-day simple moving average of the highs and a three-day simple moving average of the lows.

3. To calculate the 3x5ATR for potential resistance, add the 5ATR to the three-day moving average of the lows. To calculate the 3x5ATR for support, subtract the 5ATR from the three-day average of the highs.

Can you help me with this? Thanks in advance.
Rick

Thanks for the information. Here is the implementation.
