How the signal works
OBV accumulates volume signed by the bar’s direction, turning the flow of trades into an accumulation curve. The strategy compares OBV with its moving average: OBV above the average means accumulation and allows a long, below it distribution and allows a short.
The approach rests on the idea that a durable price move should be confirmed by volume. Its weakness is in the nature of the signal: OBV ignores the size of the move, and on forex volume is tick-based, so the curve is less reliable than on exchange instruments.
Verification on real data
This strategy’s rule is run on real quotes with no parameter fitting to history. The rule tested was “OBV Accumulation: confirming a trend with volume”:
- Long when OBV is above its own SMA(20) — accumulation is under way.
- Short when OBV is below its own SMA(20) — distribution is under way.
- The direction is held while OBV stays on the required side of its average.
Pros and cons
- Confirms the trend with an independent measure — volume.
- Smoothing by the average filters OBV noise.
- Clearly shows accumulation and distribution.
- OBV ignores the size of the move — only its sign.
- On forex, tick volume lowers reliability.
- As a trend approach it is unprofitable in a range.
Pitfalls
OBV Accumulation inherits all the weaknesses of trend strategies in a range: when price oscillates, OBV crosses its average on every move, breeding false signals. The second subtlety is forex tick volume, which makes the conclusions less reliable than on exchange instruments with real turnover.
Who it suits
For traders of exchange instruments who use volume as confirmation of direction. On forex, applicability is limited by the nature of the available volume data.
Frequently asked questions
What does OBV above the average mean?
That accumulated volume is rising faster than its average pace — that is, accumulation is under way, buyers are more active than sellers. This allows the strategy to hold a long position.
Why does the absolute value of OBV not matter?
OBV counts from an arbitrary starting point, so its absolute level is meaningless. Only the direction of the curve and its position relative to the average matter.
Does it work on forex?
With a caveat: there volume is tick-based, not exchange-based. It correlates with activity but does not equal real turnover, so signals are less reliable than on an exchange.
