Charts that utilize a periodicity of "Daily" will show a different quantity of Volume when compared to charts that utilize an intraday periodicty like 1 minute or 1 Day*. This is caused by the fact that certain types of trades, such as block trades, spread trades and market trades, are considered by the exchange when reporting the cumulative daily volume for a specific symbol or contract. However, those trades are not represented in the tick or 1-minute intraday data for the symbol. These trades together make up the difference observed between the daily volume and the sum of the intraday volume.

Reminder / 2 options for selecting a Daily periodicity : the blue highlighted option is recommended (ie daily bars built from 1 min bar data or tick data) versus the red one (Daily OHLCV data)
