What Is Slippage — and Why Does It Matter?

You click “Buy” at one price.

But when the trade is completed, the final price is different.

That difference is called slippage.

Slippage usually happens when:

◆ Market liquidity is limited
◆ Order size is large
◆ Price moves quickly
◆ The order book does not have enough depth

For smaller trades, the difference may be almost invisible.

But for larger orders, slippage can significantly affect execution costs.

This is why liquidity matters.

Deeper liquidity can help the market absorb larger orders without causing major price changes.

For professional trading teams, execution is not only about whether an order is completed.

It is also about how efficiently the order is completed.

At LightningMM, liquidity management and execution optimization are both important parts of automated market operations.

Better execution often starts with a better market structure.

Low fees are important — but how much attention do you pay to slippage?
