Loading Cumulative PnL…
How it works: Funding PnL is bucketed daily from real settlement history. Execution Cost = round-trip taker fees + live L2 orderbook slippage on both legs (−$20.02 for size $10,000). Slippage scales nonlinearly with position size — try a larger size to see thin upper levels run out.
