Get Multiple Market Orderbooks

Changed on

Endpoint for getting the current order books for multiple markets in a single request. The order book shows all active bid orders for both yes and no sides of a binary market. It returns yes bids and no bids only (no asks are returned). This is because in binary markets, a bid for yes at price X is equivalent to an ask for no at price (100-X). For example, a yes bid at 7¢ is the same as a no ask at 93¢, with identical contract sizes. Each side shows price levels with their corresponding quantities and order counts, organized from best to worst prices. Returns one orderbook per requested market ticker.
