In trading, Order routing is the path your order takes to reach liquidity (venues, pools, makers), affecting fill quality and costs. This glossary entry explains why order routing matters, how traders use it, and how to track it with evidence instead of vibes.
Quick definition
Order routing: the path your order takes to reach liquidity (venues, pools, makers), affecting fill quality and costs.
Order routing is the path your order takes to reach liquidity (venues, pools, makers), affecting fill quality and costs. The practical version is: can you define it as a field you can log and audit later?
Most trading terms become confusing when they are used as vibes instead of variables. Your goal is a definition that helps you decide size, stop, entry timing, or whether to skip the trade.
Traders sometimes confuse Order routing with market impact. Treat them as separate variables in your journal so your reviews stay honest.
Routing can change whether you get price improvement or pay spread. In fragmented markets, where your order goes can matter as much as what you trade.
If Order routing never changes your decision, it is just jargon. The term earns its place when it improves your process consistency under real market pressure.
A useful mental model: plan first (risk and invalidation), execute second (order type and fills), review last (tags and metrics).
Use it to make one decision pre-trade. Example decisions: where the stop goes, whether to take partials, how to scale size, or whether conditions are too thin to trade.
Write the rule in one sentence, then run it consistently for a week. Consistency matters because it creates comparable data for review.
If the rule fails, adjust slowly. Do not rewrite the whole system after one bad session.
If your broker/exchange exposes routing data, record venue or liquidity source. Compare realized slippage and fees across routes, especially for larger orders.
Use tags so you can slice results by regime and behavior state. The same term behaves differently when volatility changes or when you are fatigued.
Your review question should be binary: did this variable improve outcomes or reduce rule breaks? If not, simplify.
Two identical market orders fill differently because one route hits deeper liquidity while the other hits a thin pool. The difference shows up as slippage and missed price improvement.
The point of an example is not to predict price. It is to show what you would log before the trade and what you would audit after the trade.
Assuming execution is identical across venues because the chart looks the same.
The fastest way to improve order routing is to remove one failure mode at a time. If you try to fix everything, you will fix nothing.
Order routing matters most when volatility is high and the book is thin. That's where small execution errors compound into expectancy drag.
Before you trade, decide what matters more: price control (limits) or fill certainty (markets/stops). Then trade the choice consistently for one week so your data is comparable.
If you change order types every time you feel stressed, your metrics will lie to you.
Order routing is the path your order takes to reach liquidity (venues, pools, makers), affecting fill quality and costs. In practice, it matters when it changes a concrete decision like size, stop placement, or whether you skip a trade.
They are related but not identical. In your journal, track Order routing as its own variable and treat market impact as a separate context factor so you can audit each cleanly.
