Nested segment settings

`ICashSettings` — `cash`

Instrument token, tradingsymbol, recurring buy fields, order types, market protection.

`IFuturesSettings` — `futures`

Expiry chain (futuresChainByExpiry), active contract, recurring buy, lot size.

`IOptionsSettings` — `options`

CALL/PUT quantities, durations, limits, strike differences, optionChainByExpiry with CE/PE tradingsymbols per strike.

Option chain structure

optionChainByExpiry?: {
  [expiry: string]: {
    expiryDate: string;
    expiryType: ExpiryType;
    lotSize: number;
    baseDiff: number;
    strikeList: number[];
    strikes: {
      [strike: string]: {
        ce?: { tradingsymbol, instrument_token, lot_size };
        pe?: { tradingsymbol, instrument_token, lot_size };
      };
    };
  };
}

Usage in UI

Form — indexSettingForm.tsx binds to nested objects
Order pages — read segment-specific nested config
Dashboard — legacy flat fields still supported on some code paths during migration
