Updating intermarket systems after correlation shifts
Cross-market correlations used as system inputs are not assumed to stay fixed. A mechanical-trading-system built on intermarket-analysis may be updated on a recurring schedule, or the related-instruments may be replaced, so the procedure still tracks current co-movement.
- Cross-market correlations used as system inputs are not assumed to stay fixed over time.
- A mechanical-trading-system built on those relationships may need to be updated on a recurring schedule.
- When relationship-decay appears, replacing the related-instruments is an alternative to rewriting the rules so the procedure still tracks current co-movement.
- The intermarket relationship is treated as the foundation of a complete trading procedure rather than a one-off chart observation.
A pairing as a system foundation
The archive presents the intermarket relationship as the foundation of a complete trading procedure rather than a one-off chart observation. Intermarket-analysis reads a target market through prices and related series in other markets so one trade sits in a broader portfolio or regime context.
Related-instruments are the other markets or series used as inputs so the system can mimic or hedge the target relationship. A mechanical-trading-system is a fully specified entry, exit, and abstention procedure that can be tested and updated as one set of rules.
Correlations are not assumed to stay fixed
Cross-market correlations used as system inputs are not assumed to stay fixed over time. Correlation-analysis measures whether two or more markets still move together enough to justify a pairing, hedge, or lead-lag rule.
Relationship-decay is a later change in cross-market co-movement that makes an earlier pairing less representative of current conditions.
Update the procedure when the pairing changes
A mechanical procedure built on those relationships may need to be updated on a recurring schedule. When the relationship changes, one alternative to rewriting the rules is to replace the related-instruments so the procedure still tracks current co-movement.
The same procedure in more than one program
Implementations of the same procedure were supplied so the rules could be run and compared inside more than one technical-analysis program.
