Key points

  • Volume in shares is called lots and volume in TL is called traded value; Borsa Istanbul publishes both.
  • Rising volume on a rising price shows a strong move, while a rise on thin volume shows weak participation.
  • lot counts jump after bonus issues, so compare volume in TL.

Formula / calculation

TL volume = Σ (trade price × trade quantity). Average volume is usually the mean of the last 20 or 30 days; the ratio of daily volume to that average flags unusual interest.

Interpretation

Rising volume on a rising price shows a strong move, while a rise on thin volume shows weak participation. Breakouts should be confirmed by volume. Volume spikes often follow news, KAP disclosures or institutional trades.

Pitfalls

lot counts jump after bonus issues, so compare volume in TL. In stocks with a small actual circulation even small volumes move the price. Volume alone does not indicate direction.
