So all colors should match when we are in trade?
Please mark the highs and lows in OBV charts for the highest OBV level in the last completed blue ribbon period and the lowest OBV level in the last completed red ribbon period and you would get BO/BD levels of OBV for today. So fresh longs/ shorts can be taken based on BO/BD from these levels and SL's managed and trailed accordingly. This is how you capture big moves like in crude yesterday. Be with the BO/BD trend of the OBV.
Take trades as per ribbon colours only in the direction of OBV trend.
