Level 1
Last price and best bid/ask. Low bandwidth, low latency — enough for most terminals.
Level 2
Multiple book levels for liquidity analysis. Often enterprise or specific market entitlements.
Choosing a plan
See pricing for market access; contact sales for Level 2 and private deploy options.
Entitlements
Level2 usually needs higher plans or enterprise deals; confirm in console to avoid 403.
