TXSE and other exchange values documented on asset schemas

Broker API

The Exchange enum now documents the full set of values the API already returns:

• TXSE for US equities, alongside AMEX, ARCA, BATS, NYSE, NASDAQ, NYSEARCA, and OTC.
• CRYPTO, ERSX, and CRXL for crypto.
• ASCX for crypto perpetuals.
• INDEX, the artificial exchange used for index symbols such as SPX.

The AssetClass enum also adds the us_index and crypto_perp values.

Affected Endpoints

Trading API

The Exchange and ExchangeForPosition enums now document the full set of values the API already returns:

• TXSE for US equities, alongside AMEX, ARCA, BATS, NYSE, NASDAQ, NYSEARCA, and OTC.
• ERSX and CRXL for crypto, in addition to CRYPTO.
• ASCX for crypto perpetuals.
• INDEX, the artificial exchange used for index symbols such as SPX.

The exchange query parameter on GET /v2/assets now documents that it filters us_equity and us_index assets by AMEX, ARCA, BATS, NYSE, NASDAQ, NYSEARCA, OTC, TXSE, or INDEX, that INDEX requires asset_class=us_index, and that crypto and crypto perpetual assets are not filtered by exchange.
