Analysis and Trade Preparation · CFDs Trading Guide

Volatility measures movement while liquidity describes the ability to transact. They interact, but neither can replace the other in a CFD execution plan.

Distinguish movement from tradability

A market can move sharply while offering little executable depth. Another can trade actively within a narrow range. Historical volatility says little about the exact fill available for your order during a disruption. Review both price ranges and actual quote conditions, including how they change when the underlying exchange is closed.

Use session specific observations

An index CFD quoted overnight may behave differently from the same label during its main exchange session. Currency liquidity can vary across regional overlaps and holidays. Record spread and slippage by time window rather than averaging everything into one convenient number. A low average can conceal a costly period in which the strategy actually trades.

Scale the comparison

Suppose one session has a typical 40 point range and a two point spread. Another has an eight point range and a three point spread. The spread represents 5% and 37.5% of those ranges respectively. This comparison does not prove profitability, but it highlights how transaction friction can dominate a small intended move.

Adapt size without inventing certainty

A wider price range may justify less exposure for the same planned risk budget. A very quiet period can precede an abrupt jump, so low recent volatility is not a guarantee of safety. Define when the strategy does not operate, including abnormal spreads or unreliable quotes. Skipping unsuitable conditions is a valid output of research.

Try it yourself

A strategy targets a 12 point move. Its estimated spread and execution allowance rises from two points to five points. How much of the target remains before other costs in each case?

Show the worked answer

Ten points remain under the first assumption and seven under the second. The available margin for error has narrowed even though the target did not change.

Educational material, not a recommendation to trade. Numerical examples are hypothetical. CFDs involve leverage and substantial risk of loss. Availability, costs and protections depend on the contract, legal entity, jurisdiction and client classification.
