Official Closing Prices per Exchange


The final closing price on any exchange may deviate from the price of the last trade because of corrections and adjustments made by the exchange itself. With this product we provide an official closing price per exchange. It allows you to identify all stages of the closing price value change by tracking all updates from the market close to the adjustments of corporate actions.


With this product, analysts can identify:

  • The reasons behind the differences between the final closing price and the market’s last trade price

  • The frequency that exchanges perform corrections of the closing price with

  • The ways the closing prices get adjusted if a corporate action happens

What do we provide

We deliver the data daily in three files:

  • Non-adjusted closing prices equal to the price of the last trade on the market

  • Official closing prices declared by the exchange at the end of the trading day

  • Final closing prices formed by the exchange as it incorporates the effect of a corporate action into the official closing price

As a part of this product, dxFeed also provides additional data, providing more power for analysis and investigation:

  • Paid dividends

  • Split adjustment factor per instrument
