Thanks for the chart. I am not talking about RSI divergences. I was talking about statistical divergence between the two indices.
BN and Nifty are highly correlated. Therefore, if of them move ahead of the other in either direction, it forms a divergence. There usually is a limit to this divergence going by historical data. So what im saying is that the current divergence between the two indices is very high and eventually they should close this divergence.
