What are liquidity and slippage in crypto?
The order book is the list of pending buy and sell orders on an exchange at each price. Liquidity is how much volume is available near the current price: the more there is, the easier it is to move large amounts without shifting the price. Slippage is exactly that: the gap between the price you expected and the average price your order actually fills at when it "eats" through several book levels.
What is this calculator for?
Enter an amount and, by walking the real book, it tells you the average price your order would fill at, how much it would move the price (impact), and the worst price reached. Useful to size large orders and compare depth across exchanges and pairs.
What is buy/sell imbalance?
It compares how much liquidity sits on the buy side versus the sell side near the price. It is a snapshot of the book right now: it describes the current state, it does not anticipate future moves.
Frequently asked questions
What is slippage when buying or selling crypto?
It is the gap between the price you see and the real average price your order fills at when it is large enough to consume several book levels. The larger the amount and the lower the liquidity, the higher the slippage.
Why does impact differ between exchanges?
Each exchange has its own book depth. The same amount can fill with little slippage where there is deep liquidity and with a lot where it is thin. That is why the calculator lets you choose exchange and pair.
Does the estimate include fees?
No. It computes only the market impact (walking the book). The exchange's trading fees are added separately and depend on your account.
Do you store visitor or order-book data?
No. The book is fetched live for each calculation and nothing is stored; no visitor data reaches the server either.
