Relative Double Strength Index

Splits the RSI in 2 components, the rising and the falling part

- Rising: when RSI is higher than its previous value, this value is stored, otherwise 0.
- Falling: when RSI is lower than its previous value, this value is stored, otherwise 0.

A mean average (multiple settings possible) is calculated for both values, giving this indicator

Things to look for:

Rising > falling line = bullish
Rising < falling line = bearish

Spikes could possible be a turning point.

Sign for strength, for example, when the falling line is falling,
and the rising is rising -> bulllish
