#交易流动性 transaction liquidity refers to the ability of an asset or financial instrument to be bought and sold in the market quickly and without significant price changes. Recent studies have shown that as market structures become more complex, particularly with the growth of high-frequency trading and algorithmic trading, liquidity can fluctuate significantly in the short term. Especially in situations of market impact or crisis, liquidity may decrease dramatically, leading to increased price volatility. Financial regulators are actively exploring ways to improve market transparency and stability to enhance liquidity.
