Slippage And Spreads In Crypto Trading

Limit orders trade one cost for a different one

The obvious response is to stop using market orders, and it is mostly correct. A resting limit order does not cross the spread, it usually qualifies for a lower maker fee, and it cannot slip. On the numbers above, switching entries from taker to maker can cut the round-trip cost by roughly a third.

The cost it introduces is the trade you did not get. If price moves away from your limit and the setup runs without you, that missed trade has a real expected value, and it does not appear in any cost calculation. This is the honest trade-off: market orders pay a known toll for certainty, limit orders accept an unknown cost of non-execution to avoid the toll.

The workable compromise for most people is limits for entries, where waiting is acceptable, and market orders for exits, where being out matters more than the last few basis points. That is the same conclusion the order types lesson reaches from the other direction, and it holds because the asymmetry is real: missing an entry costs you an opportunity, missing an exit costs you the account.

Measure your own execution instead of estimating it

Nobody knows their real slippage until they record it, and almost everyone underestimates it. The method takes two extra columns in a journal.

1. Record the price on screen when you sent the order, and the average fill price you actually received.
2. Log the difference in basis points, positive or negative, on both entries and exits.
3. After thirty trades, take the average, and separately take the average of the worst five. The tail is what hurts.
4. Break it down by hour and by instrument. Most traders find one venue, one token or one time of day is responsible for most of the damage.
5. Add the number to your expectancy calculation. A strategy with a 0.4R average win and a 0.3% round-trip cost is a different strategy from the one in the backtest.

Costs are the most predictable thing in trading and the part beginners model least. They compound against you with perfect consistency while returns do not, which is why high-frequency approaches need an edge far larger than their advocates usually admit. Rebates can offset part of it on some venues, and the rebate calculator shows what that is worth against a given turnover. Everything else comes down to trading liquid instruments during the deep hours mapped in the trading sessions guide, in size the book can absorb, with the cheaper order type wherever speed is not the point.
