[Defillama Launches 'Realized Perp Slippage' Metric to Track True Liquidity Across Major Exchanges] Odaily Planet Daily News – Defillama founder 0xngmi posted on X, announcing the launch of a new metric centered around trading platforms — Realized Perp Slippage. The specific algorithm involves taking a snapshot of the order book right before a market order is executed, calculating the theoretical slippage the order should incur, and then comparing it with the actual slippage at the time of execution. 0xngmi added: 'The reason for tracking this metric is that we initially focused on order book liquidity, but later discovered that due to mechanisms like speed preferences, orders often cannot be executed as expected because market makers withdraw liquidity before the order is executed. Therefore, we started tracking the actual liquidity conditions.'
