FLD Crossings: What a Cross Actually Tells You

When price crosses its FLD, two things become true at once: the cycle that line tracks has just put in a turn — a trough on a cross up, a peak on a cross down — and the move now underway is roughly half done. That second part is what makes a crossing more than a signal. Measure the distance from the turn to the crossing point, project the same distance beyond the line, and you have the move's first target.

That's the whole answer. The rest of this article is the texture: how the projection works, when the FLD acts as support versus resistance, what separates a trustworthy cross from a false one, and what the failures look like — including some of mine, dated and scored.

If you're not yet sure what an FLD is — past price displaced forward by half a cycle's length — start with what an FLD is and come back. This article assumes the construction and goes straight to the behavior.

What does a cross of the FLD actually mean?

A cross up through the FLD says the tracked cycle — and, by Hurst's principle of synchronicity, possibly larger cycles with it — recently formed a trough. A cross down says the peak is in. That's the information content, and notice what it is: a statement about something that already happened, read with a line built entirely from past price. The FLD doesn't predict the turn. It confirms the turn early enough to matter.

The crosses also have addresses. One full 80-day cycle produces eight distinct meetings between price and the 20-day FLD, lettered A through H — I walk the full sequence in the eight FLD interactions. The classic cross up is the "A": an impulse up through the line after the 80-day cycle trough. When that impulse shows, the method's standing instruction is simple — notice it, and try to remain on the side of that momentum.

How does a crossing project a target?

This is the measuring rule, and it's the same every time:

1. Mark the turn — the previous trough for a cross up, the previous peak for a cross down.
2. Mark the point where price crossed the FLD.
3. Measure the distance between the two.
4. Project that same distance beyond the crossing point, in the direction of the cross.
5. Treat that as the move's first target — the method exits there, at least partially, at the 100% projection.

Two chart studies from my book show the shape of it. In one, the distance from a trough to the FLD crossing measured 13.5 points, and the projection of that distance caught the move. In another — an "F" interaction — there were 10 points from the "E" peak down to the crossing, projected downward to the "F" target; price met it and kept going, completing the 80-day cycle at "H." Same rule both times, one long, one short.

Two honest caveats belong next to the rule. High-momentum crosses overshoot their projections — the target is where the measured move completes, not where price is obligated to stop. And higher-cycle FLDs project larger targets, but exiting on the 20-day projection is a design choice: reaching for the bigger target builds a different system than this one, with a different character. Pick which system you're running before the trade, not during it.

When is the FLD support, and when is it resistance?

Where you are in the 80-day cycle does most of the deciding:

Holding strength is the pattern worth naming. If price starts to trend above the FLD and stay there, future attempts to break below it tend to fail — the line is being used. The 2019 and 2020 bull markets are full of this: the 20-day FLD supporting price again and again as it rose, often with the tops of prior bars joining the line as support. When a touch of the FLD reverses at the right time for a long — the "C" or "E" interactions — that's the line doing exactly what it's for.

Resistance is rarer, because markets spend more time bullish than not. The reliable window for it is late in the cycle: the "G" interaction, where price may reach toward the FLD without even touching it and reverse down, setting up the "H." The book's examples include an 80-day cycle ending in March 2021 — averaging 73 days — where the FLD provided consistent resistance through the "F" and "G" interactions, and a stretched 77-day cycle where repeated FLD rejections kept a trader from calling the "A" interaction too early.

Ranges are the third case and the humbling one. Sideways markets put the cycles into short-term equilibrium: price falls below the FLD and rises above it by roughly equal amounts, and the crossings carry no turn information. August 2022 built exactly that kind of range — an 80-day cycle failure plus a larger peak hitting the market together. The failure announced itself through a break of the 80-day cycle's valid trend line, the Hurst rule that says a VTL break confirms the next-higher cycle's peak — what a VTL is and why breaks matter — and failures in general get their own article: cyclic failure.

One more line from the book worth carrying around: all the cyclic FLDs in the nominal model eventually get touched. Price may bounce off a line, reach toward it and reverse, pierce it slightly, or run straight through — which of those happens depends on the smaller cycles arriving at it. After a reversal, the higher-cycle FLDs make natural objectives for at least a touch.

What separates a real cross from a false one?

Four lenses, applied to every cross: character, momentum, time position, holding strength. How things happen is information.

Character is what happens before and after price meets the line. Reversing before even touching the FLD, or using it cleanly as support, is strength. A complete penetration can mean a larger move is forming. Price failing to fully cross — the median never quite making it through — leans the other way: the line is likely to keep resisting or supporting. Small structural details count here too: whether a prior week's low broke, whether an early trough is holding as support.

Momentum grades the cross itself. A cross down from a major peak on large down days — moves of 1% or more over a week — is high momentum, and it can carry price well past the projection. In the other direction: if a major cycle low has formed and a larger cycle's projection has been met, momentum can push price up regardless of how untidy the pattern looks.

Time position is where the cross sits in the 80-day cycle — and it hides the method's most practical robustness. After a deep low that completes a larger projection, you can be genuinely unsure whether you're looking at an 80-day trough or only a 40-day one. Here's the thing: at the FLD cross, the read is the same either way. It's either an "E" or an "A" — and both are read long. The label can be wrong while the decision stays right. That's why I trade the crossing, not the count.

Holding strength carries memory. A line that has been supporting price for weeks has told you how the market treats it; the next visit starts from that prior.

What does a failed crossing look like?

Failures come in flavors: whipsaw in ranges, rejections where price reaches toward the line and rolls over, and crosses whose follow-through simply dies. And sometimes the failure is mine — a right idea on the wrong clock. Here's what that looks like in the actual record:

From the ledger — one July week of FLD reads, scored. On 2026-07-09, on the 4PM show, with the S&P weak and an FLD interaction ahead, I said our bear scans would "turn completely red" over the next several sessions. Miss — the stated window closed green, and the roll-over arrived one to two sessions after it closed. Right idea, early on timing; scored as said. On the same show I said the 80-day cycle was probably peaking, and that the buyers still holding the market up were likely to end up stuck. Hit — a marginal higher peak formed within days, and the index rolled over the following week. Every read gets dated when it's made and scored when it resolves. Misses stay on the board — a record with the misses removed isn't a record.

Questions traders ask

Is the projection a target I can count on?

No. It's a measuring convention, not a promise — the first target, and the place where the method takes the trade off, at least partially. High-momentum moves overshoot it; failed moves never reach it. The projection is where I look for the move to complete, not something price owes anyone. Treating it as the former keeps you honest; treating it as the latter is how a tool becomes a superstition.

What happens if price crosses the FLD and then crosses right back?

That's usually the range talking. In sideways markets the cycles sit in short-term equilibrium, price travels roughly equal distances either side of the line, and crossings stop carrying turn information. It's also a character verdict on the original cross — a move that slices through and holds is a different animal from one that limps through and folds. When crossings start stacking up in both directions, the most useful read is often that there's no read.

Do higher-cycle FLDs give bigger targets?

Yes — the 40-day, 80-day, and 20-week FLDs each project on their own scale, and after a reversal the higher-cycle lines are natural objectives for at least a touch. But mixing scales mid-trade changes the system. The framework in these articles trades the 20-day cycle and exits on the 20-day projection; reaching for the larger target is a different system, not a bonus round on this one.

How does this fit the rest of the method?

A crossing is one moving part: the cycle ladder above it, the A-through-H interactions around it, the VTLs that confirm what the crosses suggest. The full framework — and the public scoreboard where every dated read lands, hits and misses both — lives at the methodology hub.
