SMI Ergodic Indicator plus SMI Ergodic Oscillator in a single script: kind of a "faster MACD" oscillator (based on TSI, or so called True Strength Index) with a 20-period lookback.
Trend is bullish when crossing above 0 and bearish when crossing down, although you can use the divergences too, keep in mind the lookback period to dismiss fake long-term divergences.
Fancier default colors than when merging the two built-in indicators too!
