Gann Planetary Analysis: An Introduction

Planetary analysis maps the sky onto the chart as a second calendar, and the honest question is never whether the sky moves markets but whether the overlay survives its own testing. That is the frame for this introduction. The tool is real, the arithmetic is real, and the claim made for it is narrow. What follows is the mechanics, a worked example, and a testing protocol that decides what the method earns.

This is the most contested tool in the Gann tradition. Some practitioners treat it as the hidden core of the system; others treat it as the point where a useful calendar drifts into speculation. The lesson takes neither side: it teaches the method as the tradition uses it, then holds it to the same standard as every other tool in this course.

What the Planetary Method Actually Does

The method takes planetary longitudes from an ephemeris, treats each longitude as a position on a 360-degree circle, and projects that circle onto price and time. An ephemeris is a published table of where each body sits on each date: astronomy, computed in advance, accurate to fractions of a degree, nothing mystical in it.

When two bodies reach a fixed angular separation, the method marks a window on the calendar. That window is the entire output. The tradition then watches whether price turns, accelerates, or breaks structure inside the window.

Notice what the claim is: scheduling. Certain dates deserve extra attention because a geometric relationship completes there. The tradition does not say the relationship pushes price, and this lesson does not either.

Keep that separation strict. A calendar that says "watch this date" is testable and can earn a place in a process. A claim that a planet pulled price to a level is not testable in any way a trader can use; it can only earn faith.

A schedule is an input to decisions, never the decision itself.

The Wheel, the Longitudes, the Aspects

The mechanics start with the zodiac treated as a plain 360-degree wheel. Strip away every symbolic association and what remains is a circle divided into degrees. A body's longitude is its address on that wheel: Mars at 214 degrees is an address, nothing more.

An aspect is a fixed separation between two addresses; two bodies sitting exactly 90 degrees apart form what the tradition calls a square. Separations are fixed by geometry, so aspects can be computed decades in advance, which is why the method produces a calendar rather than a reaction.

Aspect	Separation	What the tradition reads into it
Conjunction	0 degrees	Two cycles begin together; a seed point, watched for new direction
Sextile	60 degrees	A soft, supportive alignment; continuation of the current move
Square	90 degrees	A hard angle; tension, effort, and a candidate turning window
Trine	120 degrees	A soft, flowing alignment; ease of movement, trend persistence
Opposition	180 degrees	The maximum separation; culmination, climax, and a candidate turn

The hard separations, square and opposition, carry the turning-window claims; the soft ones carry continuation claims.

Two details matter in practice. Aspects are not instantaneous: bodies move at different speeds, so an exact separation is approached over days, holds briefly, and separates, and most practitioners allow an orb of a degree or two, which stretches each aspect into a window. And faster bodies form aspects constantly, so practitioners restrict attention to slower bodies or to aspects landing inside a window already marked by the time counts from the previous lesson.

That restriction is doing real work: a calendar that marks every day is not a calendar, and selectivity is where honesty about results becomes possible.

Mapping Price onto the Circle

The projection step is where the method meets the chart. A price range is stretched across the wheel so one full turn equals the range: a market that traded from a low to a high spanning 144 points gives 144 points of price equal to 360 degrees of wheel, and every price inside that range a degree address by simple proportion.

Time is mapped the same way. Dates become degrees by counting elapsed bars or calendar days from a chosen origin, usually a major low or high, and converting that count onto the wheel by the same proportion. Now two things carry degree addresses: the price level where the market trades, and the sky on any given date.

Once both share a common scale, they can be read against each other. An aspect completing on a date whose degree address matches the degree address of the current price is called a convergence in the tradition's vocabulary. Price and time "square out" at the same address. This is the strongest configuration the method offers, and it is still only a scheduling statement: a date and a level to watch, no direction, no target beyond the level itself, and no guarantee.

One caution belongs here. The choice of origin, range and bodies are all degrees of freedom, and more choices means more chances to find a match after the fact. A method with enough dials can be tuned to fit any chart that already happened, which is why the testing protocol below matters more than any single striking example.

A Worked Example: One Aspect, One Window

These numbers are invented for teaching, the same hypothetical move used in the square lessons. A market puts in a low at 200 and rallies to a high at 344. The range is 144 points. Stretch that range across the wheel and each point of price equals 2.5 degrees, since 360 divided by 144 is 2.5.

Now find the degree address of the quarter point of the range. A quarter of 144 is 36 points, so the level sits at 200 plus 36, which is 236. Convert 36 points to degrees: 36 times 2.5 is 90. The 236 level sits at exactly 90 degrees up the wheel from the low. In the language of the method, 236 is the square of the low.

Now bring in the sky. Suppose a square aspect between two slow bodies completes on day 88 of the move. The previous lesson's count work flagged a window around day 90, since 90 is one of the core Gann counts. The aspect lands inside that count window. Meanwhile price, after pulling back from the high, trades at 234, two points from the 236 level, the 90-degree wheel mark.

The tradition reads this stack as a strong window. Three independent markings coincide: the day count from the low, the aspect completing in the sky, and price sitting on the degree address that squares the low. A practitioner following the method would treat the surrounding sessions as a period demanding attention, watching for a reversal signal, a break of local structure, or a failure to turn, each of which carries its own information.

Now the lesson's own verdict, stated flatly. Two calendars agree, and neither has said a word about cause. The day count is arithmetic on the chart's own history, the aspect is arithmetic on published astronomy, the price level is arithmetic on the range. Striking is not evidence. The stack licenses attention, not conviction: if price turns inside the window, the method scores a hit worth recording; if price drifts through, it scores a miss worth recording with equal care.

Testing the Method Honestly

Honest testing is what separates a tool from a story, and the protocol here is the same one this course applies to every indicator and every pattern. Define the signal in advance, collect occurrences in advance, and count outcomes against a fair baseline.

The protocol runs like this. Before the fact, list the next 40 aspect windows using the same selection rules every time: same bodies, same orb, same requirement that the aspect land near a count window or a squared price level. Record whether a reversal, fixed rule in advance, occurs within three days of each window's center.

Then build the baseline: 40 ordinary seven-day windows scattered across the same chart by a rule with no knowledge of aspects, counted against the same reversal definition. Markets turn often, so any wide window catches turns by chance; the baseline measures that background rate.

Here is a teaching example with invented numbers. The 40 aspect windows catch a reversal 11 times. The 40 baseline windows catch a reversal 9 times. Eleven against nine is indistinguishable from noise. A difference that small will appear and disappear across samples, and no honest reading of it supports a trading edge.

The verdict the protocol licenses is blunt: park the method until a real sample says otherwise. If aspect windows beat the baseline by a wide, persistent margin across hundreds of cases on a chosen market, the method has earned a larger role there. Until then it gets one small, bounded job: one more calendar beside the counts, marking dates already marked for other reasons.

Two rules close the lesson. The overlay never overrides price: if a window arrives and price shows no reversal structure, there is no trade. And the overlay never shrinks a stop or widens a target; risk comes from structure and the sizing work earlier in this course.

Handled this way, the method costs little and asks little. The trader still has to read structure, wait for confirmation, and manage the position. The sky is allowed to schedule the watching. It is never allowed to do the trading.

Planetary Analysis Questions

Is this astrology or arithmetic?

The mechanics are arithmetic: longitudes from a published ephemeris, fixed angular separations, and proportions that map degrees onto price and time. The interpretive layer, the claim that certain separations mark turning windows, comes from the astrological tradition, and this lesson teaches that claim as a testable scheduling hypothesis rather than a belief to adopt.

Do I need an ephemeris to follow the lesson?

No. Every number in the lesson is computed in full, and the mechanics can be learned with the worked example alone. An ephemeris, or any software that reproduces one, becomes necessary only if a trader decides to run the 40-window testing protocol on live markets.

Which aspects matter most?

The square at 90 degrees and the opposition at 180 degrees carry the tradition's turning-window claims, so the testing protocol gives them priority. The conjunction matters as a cycle starting point, while the sextile and trine are treated as continuation markers and usually play a supporting role rather than generating windows on their own.

Should I trade planetary windows on their own?

No. A window is a reason to watch, never a reason to enter, and the lesson's own test example shows a result indistinguishable from chance. Entries still require price confirmation, structure, and a defined stop, with the overlay serving at most as one calendar among several.

The Gann block closes here: angles, squares, counts, and now the sky, all held to the same standard of testable claims. The next block changes the subject entirely, from calendars to mechanics, examining how algorithmic order delivery moves price from one pool of resting orders to the next. Bring the same skepticism. It transfers well.
