Why you should know this
Liquidity affects both the price you see and the price you can actually receive.
Liquidity is the ability to trade without a large price impact

A liquid market has enough competing orders near the current price for trades to occur with limited movement. A thin market has gaps or small quantities.
When a market order crosses a thin book, it can consume several price levels. The average fill becomes worse than the first displayed quote.
Sharp movement can be mechanical
A sudden jump does not always mean important news arrived. It may reflect a large order, withdrawn liquidity, a small venue or leveraged liquidations.
Volume alone does not answer everything. We also need market depth and spread.
A familiar example

The best offer shows 100 tokens at ₱10. Only 20 are available there. The rest of a 100-token purchase fills at ₱10.50 and ₱11. The final average exceeds the headline price.
One limit to remember
Thin markets can move both directions. A paper profit may be difficult to realize when selling causes the price to fall.
How this connects to market master
Advanced execution measures depth, spread, slippage and venue quality before treating a chart price as tradable.
