1.4Liquidity, Volatility and Spread
- ·What liquidity, volatility and spread each describe
- ·How they interact to shape execution quality
- ·Why opportunity and risk usually rise together
Liquidity describes how easily an instrument can be bought or sold without causing significant price disruption.
Volatility describes the magnitude and speed of price movement.
The spread is the difference between the bid and ask price.
A highly volatile instrument may provide more opportunity but can also produce greater risk. A highly liquid instrument may have efficient execution but relatively small movements.
Opportunity and risk often increase together.
Volatility is not an edge. It is an amplifier.
During a data release, spreads can widen and price can travel through intended entry and stop levels far faster than in quiet conditions.
Examples use historical or illustrative data only. They are not live market signals.
Record the spread on your instrument at three times of day: quiet hours, session open, and around a scheduled release.
The spread is:
Higher volatility increases opportunity without increasing risk.
- 01Liquidity governs execution quality.
- 02Volatility governs movement size and speed.
- 03Spread is a real, recurring cost.
- 04Increased opportunity typically means increased risk.
