This API offers real-time, intraday and historical VWAP (Volume-Weighted Average Price) data for US equities. VWAP is a method of pricing transactions and is used as a benchmark to measure the efficiency of institutional trading or the performance of traders. For examples, it is often used as an indicator for trading performances by pension plans, hedge funds and firms that engage in algorithmic trading. VWAP for a stock is calculated by adding up the dollars traded for every transaction in that stock (price x shares traded) and then dividing by the total shares traded for a specific time period.
The following is a list of historical changes that were made to this asset. Typically, once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change. As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset, we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb. If you spot an error in our data and believe that a record needs to be updated in some way, the ProgrammableWeb team would very much like to hear from you at firstname.lastname@example.org
