The overnight session is US stock trading through the American night, which is the Indian working day, on a handful of venues approved from 2024. Volume is thin and the main exchanges are shut, so [index futures on the CME are the market price in this window](https://mochatrade.com/learn/us-market-structure/how-us-stock-prices-form). It is the same window a [contract that trades all day](https://mochatrade.com/support/what-is-a-perpetual-contract-and-does-it-expire) lives in.
