What would be the pcf that shows a stock is within a set amount from a high or low of day on previous bar? Is this possible? I seached briefly but did not find the answer.

You can create a Condition Formula for this in a daily time frame, but not in an intraday time frame.

So if you wanted price to be within $0.05 of the high for example:

H - C <= .05

Or within $0.10 of the low:

L - C <= .1
