When you place an order on FYERS, you’ll see position types such as Delivery and Overnight. These decide how long you can hold the position and in which segment it applies.
Delivery is used for equity delivery trades. When you buy shares in Delivery mode, they move to your Demat account and you can hold them as long as you want.
Overnight is used to carry forward F&O positions beyond the trading day. Unlike intraday, these are not auto squared-off and can be held until expiry or until you exit them.
On the FYERS App, this distinction is clearly shown: Delivery for equities and Overnight for F&O. On FYERS Web and FYERS Trader, you currently see only the Overnight tab for both equities and F&O. The app-style separation will be reflected on Web soon.
