Whenever you place an order in Renegade, we estimate how much money you save versus performing the same trade on Binance.
Since Renegade is a crossing network, the prices you get on Renegade are always better than Binance prices, since traders on Renegade never incur any price impact or cross the bid-ask spread.
Specifically, to calculate your savings, we simulate how much you'd pay in fees and price impact by trading on Binance, and we compare that price to the midpoint price that you get with Renegade.
