  • Hello @Kapil

    Both these fields seem related to the legacy representation of OrderBook data in the Market Price format. New domain models like Market By Order and Market By Price have the ability to define the whole book. This legacy representation of data A_PRICE_2 seems to be for up to 25 levels, while BEST_ASK2 is for 5 levels of depth.
