01
Hurst’s ladder of 20 days, 40 days, 80 days and so on is a set of typical lengths, drawn from many markets over many years. It was a brilliant shortcut in 1970, when measuring each market by hand was out of reach.
But an average describes no market exactly. Hurst said so himself: his principle of variation says real cycles wander around the nominal values.
02
Every Hurst tool depends on the cycle length. The FLD is shifted by half a cycle. Troughs are expected one cycle apart. Targets are mirrored in time.
Set the length from an average and every one of those moves with it. If a market’s real rhythm runs longer or shorter than the textbook, the FLD sits in the wrong place, crossings come early or late, and expected lows miss.
03
A common fix is to stretch the whole ladder until it fits a market better. It is an improvement, but it is still one average stretched to fit, and it keeps the fixed ratios between cycles whether the market shows them or not.
04
CyclesX starts from the other end. It measures which cycles are present in this market, in recent data, and grades each one on how clearly it stands out. Then it applies Hurst’s tools to those cycles: the FLDs, the troughs, the nesting and the targets.
The cycle lengths come from the market itself, not from a table.
| Nominal | Adjusted average | Measured and tested | |
|---|---|---|---|
| Where lengths come from | A fixed table of typical lengths | The table, stretched to fit | The market’s own recent data |
| Fits this market? | Only if it happens to be average | Roughly | By design |
| Every cycle graded for quality? | No | No | Yes |
| Adapts when rhythm changes? | No | Slowly | Re-measured as new bars arrive |
| Shows how much to rely on it? | No | No | Yes, at a glance |
Our position
Hurst gave traders the tools. CyclesX gives those tools the cycles that are actually there.
Measuring gives you Hurst’s tools applied to the rhythm that is actually there, with a clear warning when it might not be.
