Market Cycle Analysis

Any long price series contains cycles that fit the past perfectly and forecast nothing. The property that separates the two is temporal stability, so every candidate here is scored on how it holds up on sub-periods it was not fitted to, and the ones that fail are shown as discarded instead of quietly dropped.

• Cycle detection scored on five dimensions of reliability, not on amplitude alone
• Every candidate retested on sub-periods, so an overfitted cycle is visible as overfitted
• Surviving cycles projected onto the current date, with the phase each one is in now
