batcher is not a traditional order book. For example, you don’t say you want to swap 140k USDT for tzBTC at some specific price. You say you want to swap 140k USDT for tzBTC within some percent range of the next oracle price, defined in basis points. I think there might only be 3 options there. The clearing gets a bit more complicated but that’s the basic difference from a traditional order book. Your orders are placed in “next oracle price +/- some threshold” and not in specific prices
