What a trade actually costs before it is placed: live order book depth on Bybit and OKX, walked at your size. Give it a notional in dollars and it returns the average fill price, slippage against mid in basis points and dollars, the spread, the depth within 1% of mid, and which venue is cheaper for that exact size — separately for buying and selling. A size the book cannot absorb is reported as unfilled, never priced by extrapolation.
