How Prices Actually Move

A price rises when buyers are more eager than sellers — when someone is willing to pay up to get filled rather than wait. It falls when sellers are the impatient ones. That imbalance of urgency, not some fair-value calculation, is what moves the tape moment to moment.

Liquidity: how easily you can trade

Liquidity is the amount of buying and selling available at each price. In a liquid market — major currency pairs, big index futures — you can trade large size without moving the price much. In an illiquid market, a modest order can send price jumping because there simply aren't enough willing counterparties nearby.

The two forces to watch

1. 01Positioning — where the crowd already is. A market where everyone is already long has fewer new buyers left to push it higher.
2. 02Catalysts — the new information (a data release, a central-bank decision, a headline) that gives traders a reason to change their minds and act now.

Most large moves are the collision of the two: a crowded position meets a catalyst that goes against it, and the rush for the exit does the rest. Keep those two forces in mind and price action stops looking random.
