Indicator: Vervoort Smoothed Oscillator [LazyBear] by LazyBear

lazybear custom indicators stochastic oscillator

This is Mr. Sylvian Vervoort's take on improving some well-known indicators (%B and Stoch) using smoothing techniques. A combination of TEMA and WMA does a nice job smoothing out %B, derived from zero-lag “Rainbow” data series. The same Rainbow series, averaged with the typical price, smooth the Stochastic K oscillator to produce slowStoch.

Vervroot's strategy for this oscillator (detailed explanation in the reference material below):
- It must be bullish for a buy signal and bearish for a sell signal. This means that both the oscillators must be moving up or down.
- Use the oscillators for detecting divergences. Divergence even in one is still valid.
- Stoch crossing 50 is a good confirmation signal. Momentum usually is an excellent leading indicator, so keep an eye on Stoch.
