This indicator started as an experiment.
It is an RSI which is not based on the price but on the open interest.
It captures the momentum of the open interest in the same way as the RSI of the price.
Rules Open Interest (OI):
If the OI rises and the price rises = Bullish trend.
If the OI falls and the price continues to rise = bearish reversal possible
If the OI falls and the price continues to fall = Bullish reversal possible
If the OI rises and the price falls = Bearish trend
Since the OI RSI captures the momentum of the OI, it is recommended to include the price RSI for the analysis.
In the picture are marked different examples which show extreme situations
Example rose lines:
The price RSI and the OI RSI form a bearish divergence to the price and run parallel = strong bearish signal.
Example orange circles:
Price Falling. The price RSI is in the oversold zone and the OI RSI is above 53 or in the best case in the overbought zone. = Strong bullish signal
Example Blue circle:
The price RSI and the OI RSI are running parallel downwards and the price is also falling = bearish momentum.
As mentioned, this is an experiment. The tests were performed in the 4H chart
