In short
Price discovery is the process by which buy and sell orders meeting each other settle on a price at a given moment. No one sets the right number; the price is what the sequence of executions leaves behind. The fewer the participants, the less stable that process is.
Key points
- Prices emerge from orders meeting, not from a decision
- There is no correct value set by anyone
- Fewer participants make the process less stable
- It runs independently on each venue
Definition
The process by which participants' orders meet and produce the traded price of the moment — the mechanism through which supply and demand information is compressed into a single number.
On an order book, a trade prints the instant the highest bid meets the lowest offer, and that becomes the last price. A moment later new orders arrive and a different price prints. A chart line is nothing more than the record of that sequence.
The process works only when enough varied participants are posting orders. If the flow is one-sided or sparse, even small trades move the price a long way. Newly listed assets whipsaw because their price discovery has not settled yet.
Discovery also runs separately on each venue, which is why the same asset can print different prices in different places. Arbitrage tends to close those gaps — but when transfers are slow or withdrawals are suspended, a gap can simply persist.
Watch out for
- · The last price is not a price at which any size can still trade
- · In barely traded assets, a single order may be what set the price
- · Do not treat after-the-fact narratives as the established reason a price moved
