Why do markets fluctuate? The answer lies in liquidity.

Imagine the market as a race car, and liquidity as gasoline.
Institutional funds need to enter the market, and they must find enough "gasoline," which is the opposing orders.
And many of these opposing orders come from our ordinary traders' stop-loss orders.
These stop-loss orders are large in scale, concentrated in certain areas, and once triggered, must be executed, making them the most ideal liquidity sources for institutions.
"If you can't find liquidity on the chart, then you are liquidity."
Retail traders who cannot identify liquidity may become targets for market liquidation.
