Would someone please help me write a pcf that shows a price increase over the last six months, the last month, and the last week?  Many thanks,  Roy Stanford

Condition Formulas to check if price has increased over six months, one month and one week could be written using a daily time frame as:

6 months:

C > C126

1 month:

C > C21

1 week:

C > C5

A Condition Formula to check for all three would be:

C > C126 AND C > C21 AND C > C5

If you actually wanted to quantify the percent changes for each period, you would get the following Indicator Formulas:

6 months:

100 * (C / C126 - 1)

1 month:

100 * (C / C21 - 1)

1 week:

100 * (C / C5 - 1)
