OBV (Denge Hacmi): hacim trendi doğruluyor mu?

The premise

Volume should precede price. The idea behind OBV is that smart money positions before the move is visible in the chart — buying on quiet down-days, selling on quiet up-days — and that this pressure shows up in the volume profile before it shows up in the price.

Mechanically: today's OBV = yesterday's OBV + today's volume (if close > prev close), − today's volume (if close < prev close), unchanged if close == prev close. The absolute number is meaningless — only the direction and slope matter.

Divergence is the only reliable read

OBV charts often look noisy. The signal worth watching is divergence between OBV and price. Price prints a higher high but OBV prints a lower high: the rally happened on shrinking volume, which is structurally weak. Conversely, OBV rising while price is flat or down: accumulation, often preceding a reversal.

How Signodex uses OBV

Signodex tracks OBV slope and divergence from price across the chart window. The AI Signal Analyst incorporates this into its hedge-language characterisation — for instance, "OBV is rising while price has consolidated, suggesting volume conviction beneath the surface" — without telling you to trade.
