How prices move: orders, liquidity, and sentiment
Price is the last agreed trade. It rises when buyers lift offers and falls when sellers hit bids.
Ask where the orders are
A useful question is not what price should do next. It is where resting liquidity is likely to sit, and who is forced to trade. Aggressive buyers consume the offers that are already on the book. Aggressive sellers accept lower bids. When those resting orders thin out, the next print can jump.
Liquidity clusters in obvious places
Stops, round numbers, prior highs, and prior lows attract orders because many people use the same landmarks. That clustering is why a break of an obvious level can travel farther than the chart first suggests, and why a stop placed on the exact printed high or low is often the first liquidity taken.
News and thin books change the cost of being wrong
A release can reprice expectations in one print. In a thin session the same size order moves further and the spread widens. Ignoring the spread, or treating every tick as random noise, hides both the cost of entry and the places where other participants are waiting.
Takeaways
- Price moves when aggressive orders consume resting bids or offers.
- Obvious highs, lows, and round numbers often hold clustered liquidity.
- Thin books and news can widen spreads and increase slippage.
