Dollar-weighted Put-call ratio construction

A standard Put-call ratio divides the day's put-contract volume by the day's call-contract volume and treats every contract as equal. A dollar-weighted rebuild uses premium times contracts so the ratio tracks money flow, and it can be accumulated minute by minute during the session.

  • A standard Put-call ratio is the day's put-contract volume divided by the day's call-contract volume and treats every contract as equal.
  • A dollar-weighted Put-call ratio is the sum of put premium times put contracts divided by the sum of call premium times call contracts.
  • The dollar-weighted ratio can be accumulated minute by minute so money flowing into puts versus calls can be observed during the session.
  • Editorial: weighting by premium rather than equal contract counts changes the regime reading, because the ratio then follows money flow instead of ticket count.

What the standard ratio counts

This archive article shows how to rebuild a Put-call ratio so it measures money flow instead of contract counts. The steps below stay with the historical construction. Any comment on regime signals is labelled as editorial.

A standard Put-call ratio is the day's put-contract volume divided by the day's call-contract volume. That form treats every contract as equal.

Build the dollar-weighted ratio

A dollar-weighted Put-call ratio is the sum of put premium times put contracts divided by the sum of call premium times call contracts. Premium and contract size both enter the totals, so the ratio compares money flowing into puts with money flowing into calls rather than a raw contract count.

Accumulate the ratio during the session

The dollar-weighted ratio can be accumulated minute by minute so money flowing into puts versus calls can be observed during the session. The same premium-times-contracts construction is reused; only the update frequency changes.
