I'm looking to create a scan/pcf for the following 

open is near high of previous day (by near I mean a % from hod)

close is near high of day (near would be a %)

ive been trying to figure this out but I'm stuck (and I stink at converting word problems into formulas)

I'm going to use 1% for both of these. Since the open could be both above and below the high of the previous trading day, we need to check for both possibilities.

.99 * H1 <= O AND O <= 1.01 * H1

Which could also be written as follows.

ABS(O / H1 - 1) <= .01

The close can only be at or below the high of the trading day, so checking for it to be within 1% is a bit simpler.

.99 * H <= C
