On-Balance Volume Formula (Calculation)

In each trading period, the On-Balance Volume indicator is calculated depending on its value in the previous trading period: if the current closing price is above the previous one, then the current volume is added to the OBV, and if it is below - the current volume is subtracted from the OBV. If the current closing price is unchanged, then the on-balance volume remains unchanged.

OBV(t) = OBV(t-1) + Vol, if C(t) > C(t-1);
OBV(t) = OBV(t-1) – Vol, if C(t) < C(t-1);
OBV(t) = OBV(t-1), if C(t) = C(t-1),

t – current period;
t-1 – previous period;
C – close price;
Vol – volume.

Do Indicators Work in Forex?

There are 2 types of indicators: lagging and leading. Lagging indicators base on past movements and market reversals, and are more effective when markets are trending strongly. Leading indicators try to predict the price moves and reversals in the future, they are used commonly in range trading, and since they produce many false signals, they are not suitable for trend trading.
