On Balance Volume Surrogate Indicator Review


On Balance Volume Surrogate is an indicator created in March 2015 by developer Stanislav Korotky. This indicator is an edition of the ‘On-Balance Volume’ indicator that is based upon pseudo-real emulated volumes of tick volumes. It calculates an estimate close to the actual distribution of the trading volumes of Forex instruments (where only tick volumes are available) and then applies the conventional OBV formula to them.


The volumes are calculated by the same algorithm that is used in the True surrogate volume indicator. The indicator itself is not necessary but can be used as a reference. The main parameters of On Balance Volume Surrogate are as follows:

  • Ma fast – mean rapid movement period (EMA), default – 3; if set to 0, the mean is not calculated
  • Ma slow – mean slow movement period (EMA), default – 7; if set to 0, the mean is not calculated

Alert on Macross – alert switch for a crossover of moving stockings, by default – false (alert is disabled); alert is signaled only once per bar; alert message format: “Obvsurrogate [Symbol] [Timeframe] UP/DOWN cross @ [Time]”

Completed bars – an option that controls how the crossover of moving stockings is marked: in the last bar or in the previous bar (Completed bars is true); by default – true, so alerts can be generated at the opening of the bar only; note, that a signal on the downhill turn is not necessarily followed by a signal on the upturn (or vice versa) – in some cases when the moving averages fluctuate near the other, you can get several successive signals (in different bars) in the same direction you should consider this as a signal confirmation.


The indicator shows 3 lines:

  • Green thickness – cumulative volumes according to the OBV formula
  • Thin red – fast-moving medium
  • Thin yellow – slow-moving medium

Trading with On Balance Volume Surrogate

The indicator should be used for trade in the same way as conventional OBV is used:

-By means of passing signals of moving averages;

-Divergence/convergence between OBV and price; if their directions contradict – a reversal is expected (the current trend is about to change);

-The constant movement of OBV and price; confirms the current trend.
