Struct OBV

pub struct OBV { /* private fields */ }

On Balance Volume (OBV) Indicator

OBV is a momentum indicator that uses volume flow to predict changes in stock price. It adds volume on up days and subtracts volume on down days.

Formula:

• If Close > Previous Close: OBV = Previous OBV + Volume
• If Close < Previous Close: OBV = Previous OBV - Volume
• If Close = Previous Close: OBV = Previous OBV
