Slippage

Slippage is the gap between the price you expected when you placed a trade and the price at which it was actually filled. If you intend to buy at one price but the order executes slightly higher, the difference is slippage. It is a normal cost of trading, not a glitch.

It happens because prices move and liquidity is finite. In a fast-moving market, the price can change in the instant between deciding and executing. In a thin market, a large order can exhaust the available offers at one price and fill the rest at worse ones. Both widen the gap between intention and result.

Slippage matters most to strategies that trade frequently or in size, where small per-trade costs compound. A low-frequency approach like Crypto Wealth, which acts roughly once a month per asset on the 4-hour timeframe, is far less exposed to it: fewer trades mean fewer chances for slippage to accumulate.
