I am looking for a scan this will show me when the ave price on a Heiken Ashi Candle crosses the 8 EMA. Thank you for any and all help

You don't need a PCF for that. Set your plot style to Heiken- Ashi and add an 8 period EMA to the price.  Then click on Price and select Create Scan Condition and set the Condition to Crossing Up Exp Mov Avg 8.

I am not looking for just the price to be above the 8EMA. I am looking for the main body of the Heiken Ashi Candle to be crossing above the 8EMA . The price and the body of a Heiken Ashi are never the same . The body is just an Ave of the price. If it were a simple candle what you told me would of worked fine.

The Close of an HA candle is the average of price. But I understand what you're asking for now. You want the candle body straddling the EMA.  I don't know how to do that with a PCF.

Calculating the Modified Bars 
Normal candlestick charts are composed of a series of open-high-low-close (OHLC) bars set apart by a time series. The Heikin-Ashi technique uses a modified formula:

• xClose = (Open+High+Low+Close)/4 
  o Average price of the current bar
• xOpen = [xOpen(Previous Bar) + Close(Previous Bar)]/2 
  o Midpoint of the previous bar
• xHigh = Max(High, xOpen, xClose) 
  o Highest value in the set
• xLow = Min(Low, xOpen, xClose) 
  o Lowest value in the set

Ok thanks for the try . Any of the members reading this . Do you guys know how to write they type of PCF?

Try something like this and see if this works for you

Thank you busterram ! I was able to make what you sent me in the PCF work . Thanks for taking the time to write the PCF out.
