Crypto Trading Deep Dive
Execution, Slippage, and Fees
Microstructure, order books, perps, funding, and algorithmic execution.
In this lesson
- How execution costs affect returns
- Why slippage and fees must be part of strategy design
Key takeaways
- 1Spread, liquidity, fees, and order type determine execution quality
- 2Small edges can disappear after costs
- 3Backtests need realistic fills to matter
Lesson summary
The intermediate question behind execution, slippage, and fees is simple: trading edge is only real after costs and fills.
Mental model
Execution, Slippage, and Fees in plain terms
The intermediate question behind execution, slippage, and fees is simple: trading edge is only real after costs and fills. The concept becomes useful only when it improves a real decision about custody, execution, liquidity, or protocol risk.
- How execution costs affect returns
- Why slippage and fees must be part of strategy design
Mechanics
How to reason about execution, slippage, and fees
Execution, Slippage, and Fees starts with spread, order book depth, AMM curves, fee tiers, funding, and latency determining actual entry and exit prices.
When reviewing execution, slippage, and fees, separate what the interface shows from what the protocol, market, or custody layer can actually guarantee.
The concept is only learned when the learner can use execution, slippage, and fees to reject a weak setup, not just describe a strong one.
- Spread, liquidity, fees, and order type determine execution quality
- Small edges can disappear after costs
- Backtests need realistic fills to matter
Example
Execution, Slippage, and Fees in a real decision
For example, a backtest can show profit before fees while live fills lose money because the strategy trades too frequently in thin books. The lesson is useful only when the learner can name which evidence confirms the claim and which condition would invalidate it.
Common mistakes
Where people slip up with execution, slippage, and fees
A common mistake with execution, slippage, and fees is assuming the chart price is the executable price. That shortcut makes the concept feel simple while hiding the part that can actually create loss.
Risk notes
Reading the risk in execution, slippage, and fees
The main risk is partial fills, widening spreads, hidden fees, funding drag, and market impact can erase a small statistical edge. In practice, the risk becomes larger when markets move quickly, liquidity thins, or interfaces compress important warnings.
- Include fees and spread.
- Estimate market impact.
- Reject trades with weak net edge.
Practice
Make execution, slippage, and fees stick
- Include fees and spread.
- Estimate market impact.
- Reject trades with weak net edge.
Review
Key terms
- Custody
- Who controls the private keys. Custodial = a third party holds them; non-custodial = you do.
- Liquidity
- How easily an asset can be bought or sold without moving its price much.
- Order Book
- A live list of resting buy and sell orders at each price level.
- Slippage
- The difference between expected and executed price, common in low-liquidity or fast markets.
- Spread
- The gap between the best bid and best ask.
