Hello Trainers,
I want to scan for stocks where price has been in in uptrend and now bar range has been reduced for X number of previous bars. I have done a regression sort to find the uptrending scan. I want to know how to make a PCF to scan for NRB during last X number of days,.

Thanks in advance

If you want to find out if the current Range is less than previous Range, you could use:

H - L < H1 - L1

If you want to find out if the current Range is less than the Ranges of the previous two Bars, you could use:

H - L < H1 - L1 AND H - L < H2 - L2

Adding additional days merely requires adding more AND H - L < Hx - Lx bits to the end:

NR3:

H - L < H1 - L1 AND H - L < H2 - L2 AND H - L < H3 - L3

NR4:

H - L < H1 - L1 AND H - L < H2 - L2 AND H - L < H3 - L3 AND H - L < H4 - L4

NR5:

H - L < H1 - L1 AND H - L < H2 - L2 AND H - L < H3 - L3 AND H - L < H4 - L4 AND H - L < H5 - L5

What if i have to look for narrowing range i.e. not necessarily narrowest range in the last x bars. Can i use <= operator

Yes you can use less than or equal to instead of less than if you want. You can also check for narrowing bars instead of just checking for the last bar being the narrowest by incrementing the first part of the comparison instead of just the second. If you want to find out if the current Range is less than or equal to the previous Range, you could use:

H - L <= H1 - L1

If you want to find out if the current Range is less than or equal to the previous Range while that Range is also less than or equal to the Range of the bar before that, you could use:

H - L <= H1 - L1 AND H1 - L1 <= H2 - L2

Adding additional days merely requires adding more AND H(x-1) - L(x-1) <= Hx - Lx bits to the end:

NR3:

H - L <= H1 - L1 AND H1 - L2 <= H2 - L2 AND H2 - L3 <= H3 - L3

NR4:

H - L <= H1 - L1 AND H1 - L2 <= H2 - L2 AND H2 - L3 <= H3 - L3 AND H3 - L4 <= H4 - L4

NR5:

H - L <= H1 - L1 AND H1 - L1 <= H2 - L2 AND H2 - L2 <= H3 - L3 AND H3 - L3 <= H4 - L4 AND H4 - L4 <= H5 - L5
