This endpoint returns option “times and sales” data that’s decorated with pre-trade level-1 orderbook data and post-trade level-1 data. This is the core dataset of the Amberdata direction and GEX “Gamma Exposure” analysis. We use this orderbook impact to analyze the true aggressor of every trade, while assuming that market-makers (aka “dealers”) are typically the passive trade participants. Some exchanges, such as “okex” and “bybit” will have volatility values in decimal format (ex: 97% iv will be noted as 0.97)
