I am using my following Custom PCF Indicators for Value:

In 78 Days # Gaps Up:

CountTrue((O>H1 AND H>H1),78)

In 78 Days # Gaps Down:

CountTrue((O>L1 AND L>L1),78)

I've chosen 78 Days simply because of its' fast calculation speed.

1) Is it possible to code how many Gaps Up occur than Gaps Down in 78 Days (or whatever number of days that can be calculated fast)?

2) And, the inverse: How many Gaps Down occur than Gaps Up in 78 Days (or whatever number of days that can be calculated fast)?

I am not quite sure how your request differs from what you are already doing. Although I would think Gaps Down would actually be the following based on your Gaps Up code.

CountTrue(O < L1 AND L < L1, 78)

In order to express myself more clearly, let's consider the ETF DUST today. 

It's showing 18 Gaps Up and 45 Gaps Down in the last 78 days (on a Daily chart).  So the difference between the Gaps Down and the Gaps Up is 27.

I hope this helps.

Using your version of Gap Down.

CountTrue(O > H1 AND H > H1, 39) - CountTrue(O > L1 AND L > L1, 39)

Using my suggested version of Gap Down.

CountTrue(O > H1 AND H > H1, 39) - CountTrue(O < L1 AND L < L1, 39)

Thanks, I will work with these.

You're welcome.
