Visible depth helps explain whether a market order is likely to pass smoothly or chew through worse prices.
Why this lesson matters
Visible depth helps explain whether a market order is likely to pass smoothly or chew through worse prices.
The core idea
- Thin depth makes market execution more fragile.
- Larger size increases the chance of slippage.
- Checking depth can change the order choice before you trade.
Practical example
A small order in a deep market may fill cleanly, while the same order in a thin market can move through several price levels.
Common mistakes to avoid
- Using market orders without checking depth.
- Comparing your planned size with last price only.
- Ignoring slippage because the headline spread looks acceptable.
Quick checklist
- Check depth
- Check spread
- Compare size
- Consider limit order
Key takeaway
A good lesson improves judgment, risk control, and execution discipline before it changes action.
Important caution
Execution risk rises quickly when visible liquidity is shallow.
