You asked about the effect of place, I Checked It and sent the result, when I "m changing the place, it cause some errors...please see the pic

[Jean]

no i did not ask, i told you the error had to do with place.
For a progression in tri/quadwheel, the place that is used is always the birthplace.

[Jean]

now, do you still have errors?

[Eng.Mohebi]

Hi Jean..
Yes
I think either you do not fully understand what I mean or I do not understand what you mean.
Surely you really know how to progress the chart and therefore  you can check whether the program calculations are correct or not?
For example, in methods Secondary and Quotidian, we use the position of the planets on the first and second day of birth to progress, and my control tool is to use the horoscope of these two days. In fact, at the beginning and end of the first year of birth, the position of the planets in the Progress Chart should be equal to the position of the planets on the first and second day of birth horoscope, while if you check, there is an error.
Or, for example, the only difference between Secondary and Quotidian is in the progression of the ASC and MC,in Quotidian method, 360 degrees should be added to ASC and MC and then progress should be made, but in any case, the position of these two points at the beginning and end of the year in both methods should be the same. But if you check the software, the position is different in them.
In each image, which is related to one of the each methods of progressing, I put the position of the planets on the first and last day of the year, along with the first and second day of birth, and showed the errors that exist. The only method that calclulations are corect, is solar arc and its error is about a few seconds.

Are you sure you have the latest version? There has been a version where i thought the bug was fixed but triwheel could still be in error if there was a transit in a slot before the progression.
My co-worker Ed and I have checked with astro.com, we don't have errors anymore, for some reason the moon is some seconds off, but asc / mc are ok.

I'm confused.....it's 1/6/2021 version

[Jean]

look.
with astrodienst, some cusps are a bit off, shrug.

[Eng.Mohebi]

thanks ....could you please set your date and time of progress on 1968/2/4 11:5:34 (birth time and date) then check

[Jean]

i already tried that, i get exactly the same horoscope.
Only some cusps are a bit off due the the house calculations for naibod progression.

[Eng.Mohebi]

See this one

[Jean]

sorry i wouldn't know what to do about that, house caculation is different when you do progressions. My *only* benchmark is astrodienst. Just tried that and the result is the same as mine.

[Eng.Mohebi]

sorry jean, this is from asto.com...as you can see, when you put your  progress day on birth date, all data from radix horoscope and all type of progression must be same....un planet dance just Solar arc and quotidian are same

[Jean]

i'm giving up on this, sorry. As said, i wouldn't know what to do, for me it's good enough (tm).

[Eng.Mohebi]

It's up to you... it's so simple that you set the date of progress chart on birth date, both progress and birth horoscope must be same, but when it's not, something is wrong..it doesnt need any calculation...you can ignore it or make it correct...
finally thanks you for everything

Hi there - I see you are using sidereal - True Citra. I think this is the root of the problem. I will let Jean know. See screenshots. The tropical version is first - which is correct. The sidereal version is second which shows the errors. Ed
