Research useful first FX analysis metrics

[BytecodeBrewer]

Goal

Identify simple but meaningful metrics for analyzing exchange-rate data.

Research questions

• What simple metrics are useful for FX time series?
• Which metrics are realistic for a beginner-friendly Python project?
• What can be calculated from daily exchange rates?
• Which metrics are visually useful in charts?

Candidate metrics

• Daily percentage change
• Absolute change over time
• Rolling average
• Min/max rate in selected period
• Volatility approximation using standard deviation
• Strongest and weakest currency movement in a sample

Deliverable

Create docs/fx-analysis-research.md.

Acceptance criteria

• 4–6 simple metrics are listed
• Each metric has a short explanation
• Each metric has a possible chart idea
• One metric is selected for first implementation
• Research stays practical and project-oriented
