System Price Format

The T4 system publishes market prices in two formats, Decimal and Real. The selected format controls where we place the decimal point on all prices published on the system, including chart data.

The Decimal format represents the prices exactly as published on the various exchange API's. This is the default for T4.

The Real format represents the prices as most trade screens, displays and websites would typically display them.

The price format setting determines how price values are returned in API responses. You can configure this during the login process for both API and REST authentication methods.

• Real - Returns prices in real/decimal format
• Numeric value: 1 - Alternative way to specify Real format

When creating your login request using the API, include the PriceFormat parameter:

loginRequest = new T4Proto.V1.Auth.LoginRequest 
{
    Firm = *demoConfig.Firm,
    Username = *demoConfig.UserName,
    Password = *demoConfig.Password,
    AppName = *demoConfig.AppName,
    AppLicense = _demoConfig.AppLicense,
    PriceFormat = T4Proto.V1.Common.PriceFormat.Real  // You can also use the value of 1, it is the same.
};

For REST API authentication, you have two options:

If you obtain your bearer token from the streaming API, the price format is already configured and no additional setup is required.

If you use the /login REST endpoint directly, include the priceFormat parameter in your JSON request:

{
    "firm" : "CTSDev",
    "userName" : "user",
    "password" : "*****",
    "appName" : "TradeBook",
    "appLicense" : "F18CC97E-42D1-478A-8CE9-0A850B5C47A7",
    "priceFormat" : "Real"
}
