This is the finalized code released to the public that I created in a video linked here.
This indicators combines a Bollinger Band and Stochastic RSI to produce signals for possible price reversal. The signals are displayed by default as green arrows for bullish and red arrows for bearish .
To trigger a signal the indicator checks for the following:
( Bullish ) A candle closes above the upper Bollinger Band The following candle closes within the upper Bollinger Band The RSI Stochastic is below the set threshold (10 by default)
( Bearish ) A candle closes below the lower Bollinger Band The following candle closes within the lower Bollinger Band The RSI Stochastic is above the set threshold (90 by default)
