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

Please try the following:
