Is it possible to create a Custom PCF Indicator that would count the number of trades (ticks) for the last 15 seconds, the last 30 seconds, and the last minute (Trade Count)?

I would like the ability to:

   View Trade Count as a plot on Charts (5 minute, 3 minute, 1minute)

   Use Trade Count in Scans and Watch Lists (15 Second, 30 Second, 1 Minute)

If we can’t count All Ticks, can we count up ticks using a Custom PCF Indicator?

Please provide a sample of the code.

Thanks for your help!
