I would like p c f  for volume crossing the 15 period m/a

ferriers,

A conditon formula for Volume crossing UP it's own 15-period simple moving average could be writtien as:

V>AVGV15 AND V1<=AVGV15.1

A condition formula for Volume crossing DOWN it's own 15-period simple moving avergae could be written as:

V<AVGV15AND V1>=AVGV15.1

A condition formula for Volume crossing through it's 15-period simple moving average in EITHER DIRECTION could be written as: 

SGN(V-AVGV15) <>SGN(V1-AVG15.1)

You could also perform this as an EasyScan to scan for stocks that either Cross Down the Moving Average of 15 or to scan for stocks that Cross Up the Moving Average 15. 

Plot Volume on your chart by right-clicking on your chart and select Add New Plot to Chart. This will automatically add the Moving Average indicator as well. 
Click the Indicator label for Moving Average and edit that to 15. 

Now you should see Volume and Moving Average 15. Click the Indicator label for Volume and select Create Scan Condition..

Select the Condition (Greater Than) and look for the category Volume vs Moving Average 15and select either Crossing Down Moving Average 15 or Crossing Up Moving Average 15. 

Change your Time Frame to Daily and select to either Add to an Existing WatchList or Scan - OR- Scan in New Window. 

Now you are ready to Scan.

Thanks Brucs

Fwiw, flags wedges, pennants etc  are inside bars on time frames about 5-8 x the one you are viewing. 

Head and Shoulders are simply pivots in the time frame 5-8 times higher.
