WaveTrend Oscillator is a port of a famous TS /MT indicator.
When the oscillator is above the overbought band (red lines) and crosses down the signal (dotted line), it is usually a good SELL signal. Similarly, when the oscillator crosses above the signal when below the Oversold band (green lines), it is a good BUY signal.

I have marked some cross-overs in the above chart. As you can see, they are not the only useful signals WT generates. Try it on your instrument and let me know what you think.
