But the eg of this lunar year in Delta as i understand it is 1 lunar year is how many cycles of the moon is in a year. SO IF its on average a 28 day cycle for the moon to orbit the earth as I understand it, THEN is there 12 or 13 lunar cycles in 356 cal days?

Sorry typo error meant 365 days NOT 356 days

Hi CJ

IF I recall you have the delta book.

What I was asking Skimble shanks was about the Delta yearly cycle.

If you look in the Delta book there is an example of How Jim Solman ( Forgive me if ive got his name wrong without rechchecking ) found the yearly lunar cycle based on tidal tables.

When one works out the amount of days between the two dates he mentioned it was 353 cal days.

I was trying to compare this to the ammount of moon cycles in 1 year , ie the amount of times the moon revolves around the Earth in 1 standard year as we know it ( 365 cal days )

IF the moon Averages 28 cal days to complete its revolution around the Earth, then in one period of 365 cal days it makes 13 cycles. 13 x 28 cds = 364 cal days. ( HOWEVER I DONT doubt 28 cal days is only an estimate and it could be 28.6 or even 29 cds Ill Have to try and re check )

If it was only 12 revolutions in a year this is 12 x 28 = 336 cal days

What I was saying in the Delta eg as I describe above, It was 353 Cal days. THIS is inbetween the 12 or 13 revolutions of the Earth.

Upon testing this 353 day cycle I DIDnt find it greatly consistant.

In the 12th March 03 Low on the SPX to the March 5th to 8th Top we did see a turn in the mkt of about 366 - 7 days = 359 Cds

( I say 366 as year 2000 was a leap year) and if I take the 12th and - 5th I get 7 days. IF I took the 8th from the 12th id get 4 days to take away from 366 which would give 362 days NEAR to 13 moon cycles.

So that example is close to the Lunar year based upon 13 lunar revolutions in 1 year or 365/366 cal days

BUT ITs NOT 353 ! MAYBE IM being to critical as its only 6 to 9 days out.

BUT thats ONLY one example that Ive found it relatively close.

IM just trying to find out if it has any real true accuracy.

Hope you understand roughly what im trying to find out..

I WAS Writing too quickly I should have said 2004 was a leap year NOT 2000 in the above eg
( although year 2000 was a leap year four years before)

Just found this link on the moon

http://www.astro.uu.nl/~strous/AA/en/antwoorden/maan.html#v283

this was under a question How many times does the Moon orbit around the Earth each year? in the Question and Answers section

I gets a bit Complicated AND IM NOT sure which Value I should consider

27 days 7 hours OR even upto 29 days are mentioned between whats described as Sidereal and Synodical months.. ANYone any Ideas ????

the sidereal month: the period after which the Moon has returned to the same position (longitude) between the stars. On average, the sidereal month is now 27 days, 7 hours, and 43 minutes long. There are on average about 13.37 sidereal months in a tropical year.
the synodical month: the period after which the Moon attains the same phase again. The synodical month is now 29 days, 12 hours, 44 minutes, and 3 seconds on average. The are on average about 12.37 synodical months in a tropical year.

The Month
It takes the Moon one month to orbit around the Earth. There are no mile markers in space, so you can only tell if the Moon has completed another orbit if you compare its position with something else. You can pick different things to compare its position with, so you can define different kinds of months.

the calendar month: a period of between 28 and 31 days that divides calendars. In some calendars, such as the Gregorian calendar that is used in the West, the months are no longer directly tied to the phases of the Moon. In other calendars, such as the Jewish and Islamic calendars, each month starts with a specific phase of the Moon. In some calendars (such as the Gregorian calendar and the Islamic calendar) each year has 12 calendar months, in other calendars (such as the Jewish calendar) some years have 12 months and some have 13 months, and in yet other calendars there are still other numbers of months in a year.
the sidereal month: the period after which the Moon has returned to the same position (longitude) between the stars. On average, the sidereal month is now 27 days, 7 hours, and 43 minutes long. There are on average about 13.37 sidereal months in a tropical year.
the synodical month: the period after which the Moon attains the same phase again. The synodical month is now 29 days, 12 hours, 44 minutes, and 3 seconds on average. The are on average about 12.37 synodical months in a tropical year.
the tropical month: the period after which the Moon returns to the same position relative to the vernal equinox. On average, the tropical month is now 27 days, 7 hours, 43 minutes, and 12 seconds long. There are about 12.37 tropical months in a tropical year.
the anomalistic month: the period after which the Moon returns to the same position relative to its perigee. This month is currently 27 days, 13 hours, and 19 minutes long on average. There are about 13.26 anomalistic months in a tropical year.
the draconitic month: the period after which the Moon returns to the same node of its orbit. On average, this month is now 27 days, 5 hours, 5 minutes, and 6 seconds long. There are about 13.42 draconitic months in a tropical year.
Except for the calendar month, none of these months fits into a calendar year a whole number of times, so there is always a bit left over.

I just discoved this !!!!

If I use the moons revolution around the Earth as 27 hrs and 5 hrs ( Draconitic month )as one of the examples and x it by 13

I get 353 cal days This is the cycle used in Deltas 1 year cycle... ......

27 days x 13 = 351 calendar days

5 hrs x 13 = 65 hrs...... 65 / 24 hrs = 2.7 days

351 days + 2.7 days = 353.7 cal days.

I wonder !

(the draconitic month: the period after which the Moon returns to the same node of its orbit. On average, this month is now 27 days, 5 hours, 5 minutes, and 6 seconds long. There are about 13.42 draconitic months in a tropical year.

Welles Wilder wrote a brilliant book (new concepts in technical trading) as well as developing some useful indicators. Then He went and wrote the Delta Phenomenon, which is apparently about how the markets are cyclical and in tune with lunar and solar cycles. Normally I would dismiss this as utter rubbish, but its difficult given Wilders pedigree.
My thoughts exactly.

I got my copy of The Delta Phenomenon via eBay; copies do come up occasionally. It was shipped from the states and cost about £35 all in. I'm currently writing my own (basic, in more ways than one) software to 'solve delta' for medium, intermediate and long term. It's encouraging that some posters here have found the Delta principles to be of use.

I hate the style of the book, though.

I'd not get too bogged down in decimal points of days in a Delta period, Delta doesn't for a start!
I'd agree with the presentation comment - the small book that accompanies it (the secret to wealth or whatever it's called) is cringingly bad, however, making the Delta book itself almost normal by comparison <g>
One thing you can't say about W-W, 'modest, unassuming guy, isn't he?'

Its hard to do when there's two inversion points ( At the end on the 4 day cycle & the start) ie blue & orange days...( which our friend mr wilder leaves out of the book)

Btw today was a blue day..... ( On the S&P)

If Mr copan wants to post...all the better :cheesy:
he can explain the inversion thing better than I ))

i looked at some software called wave59 (i think) a few years ago which incorporated astrological predictions which seemed highly accurate. Didnt have time to test properly and have always meant to investigate further but not got round to it yet.
