I'm working on a PCF for finding flat top setups.  End goal is to have a PCF that I can use as a scanner to find stocks that have 3 or more EQUAL or NEARLY EQUAL tops.

So I'm starting with simply current high is equal to a previous high

(H = H1)

or

(H = H2)

But I'd like to give a little more flexibilitiy to cast a wider net. 

Is there a way I can say current high is within 2 cents of previous high?

(H = H1 + .01) or (H = H1 +.02)

That type of formual doesn't seem to work...is there anything I could do that might work better to achieve a similar end result?

Any other ideas would be welcome!

Are there any plans to include the ability to do pre-market scanning? 

Thanks Bruce

I don't think Vol Buzz is still available

Does the Volume Surge indicator take into account time of day.  If not, is there a volume indicator that does?  I'd like to be able to run intraday scans for above relative volume.

For example, a Gapper that by 9:45 has traded 500k shares.  It's 100 day avg volume is 1million shares.  It is not above avg on the daily volume but relative to time of day, it is. 

Thank you,
