About the model: this uses a simplified constant-product estimate, slippage ≈ order size ÷ (liquidity depth + order size). Treat it as an order-of-magnitude guide only; real slippage depends on the actual order book / pool shape, how depth is distributed, and the market at the instant you trade, and it's often worse outside trading hours. You estimate the liquidity depth yourself. This tool stays offline, fetches no live data, and is not investment advice.
How to slip less
Break orders into small tranches, avoid the thin book late at night, and set a slippage limit. For background, read Fees and Slippage and 24-Hour Trading Sessions; to check whether now is a good time, use the Market Hours tool.
Set up your Binance account and wallet, then trade during liquid hours and buy small and in tranches — steadier that way.
