[mschunke]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

The return values from .getOptionChain type notation present the Greeks with an uppercase initial letter (i.e. Delta, Gamma, Theta, Vega, and Rho. However, the actual API response is in lowercase, i.e. delta, gamma, theta, vega, and rho.

Intelisense/Typescript:

API response:

{
  Symbol: 'AAPL',
  Type: 'P',
  ExpirationDate: '2025-10-10',
  StrikePrice: 280,
  LastPrice: 256.08,
  LatestQuote: { BidPrice: 23.36, AskPrice: 24.55 },
  Greeks: {
    delta: -0.9211,
    gamma: 0.0095,
    theta: -0.0376,
    vega: 0.0813,
    rho: -0.121
  }
}

Expected Behavior

Have the same letter case on both the API and Typescript definitions.
