Why you should know this
Prices do not move because a chart decided to move. People, firms, protocols and infrastructure act for different reasons. Learning to separate who may be acting, what they may want, and what evidence we can actually observe helps us avoid turning a plausible story into a fact.
The maker is paid for taking uncomfortable risk
Spreads and fees compensate for inventory risk, volatility, adverse selection, operational costs and hedging. A tight spread in a calm market can widen quickly when informed or urgent flow appears.
Adverse selection changes quotes
If a maker suspects that incoming orders are better informed—for example around a fast-moving event—it may quote wider spreads, smaller size or stop quoting. Liquidity can therefore disappear exactly when traders want it most.
Reader risk: assuming displayed liquidity is permanent
Order-book depth can be cancelled, moved or consumed. AMM liquidity can also become much more expensive to use as pool balance changes.
Before trading size, compare quoted spread, depth, expected slippage and the behavior of liquidity during volatile periods.
Practice check — no money needed
Choose one fictional market move and write two different participant explanations for it. For each, state the incentive, observable evidence, reader risk and what would falsify the story. No money or live trading is needed.
The goal is not to identify a hidden actor with certainty. If you can explain the mechanism, name the main limitation and state what evidence would strengthen or weaken your explanation, the lesson has done its job.
How this connects to market mastery
Participant analysis sits between market mechanics and market interpretation. The same habit later supports execution analysis, liquidity assessment, risk control and scenario building: identify the actor, identify the constraint, then test the story against evidence.
