How can I create a PCF for TRIX so I can create a custom scan base on TRIX

How do you wish to calculate TRIX and what Period do you wish to use?
TRIX I:
1) EMA(1): Calculate the Pperiod EMA of closing price.
2) EMA(2): Calculate the Pperiod EMA of EMA(1).
3) EMA(3): Calculate the Pperiod EMA of EMA(2).
4) TRIX: (EMA(3)[today]  EMA(3)[yesterday]) / EMA(3)[yesterday]
TRIX II:
1) EMA(1): Calculate the Pperiod EMA of the logarithm of closing price.
2) EMA(2): Calculate the Pperiod EMA of EMA(1).
3) EMA(3): Calculate the Pperiod EMA of EMA(2).
4) TRIX: EMA(3)[today]  EMA(3)[yesterday]
TRIX III:
1) EMA(1): Calculate the Pperiod EMA of closing price.
2) EMA(2): Calculate the Pperiod EMA of EMA(1).
3) EMA(3): Calculate the Pperiod EMA of EMA(2).
4) TRIX: EMA(3)[today]  EMA(3)[yesterday]
