In traditional order-book based markets, as a trade grows larger it consequently clears out more and more lower priced orders such that the average price for a large trade would be higher than that of a smaller trade (the larger the trade, the more expensive it becomes to complete as it chugs through the order-book leaving only higher and higher priced orders to consume). This market depth -the number and size of the orders (liquidity) in the orderbook- determines how large of an order the market can process without significant price impact. Because SIREN does not use an order-book, there is no inherent unavoidable price impact; theoretically, a trade that would consume all the liquidity in the SIREN AMM could be completed at a single static price.
