What the Angel One package is
The downloadable Windows build is intended for the Angel One SmartAPI workflow. It is one component of a trading setup: you also need an eligible broker account, API access under the broker’s current rules, a compatible device and a strategy whose rules you understand.
The package does not guarantee that every broker feature, order type, instrument or account configuration will be supported. The exact behaviour can depend on the app version and changes to the broker API. Confirm these details with support before relying on the software.
