There are three main lines of thinking.
Ptolemy uses the Lot of Fortune, the Almuten of the Lot Fortune and any Planets that aspect the Almuten of the Lot of Fortune. The Almuten of anything is simply that Planet that has the greatest amount of Dignity at a particular point on the chart.
33°24' is the same as 3° Taurus 24'. Venus is the Sign Ruler and Term Ruler, while Moon is the Exaltation Ruler. In a Day Chart, Venus would be the Sect Triplicity Ruler, so Venus has the greatest Dignity in that point. However, in a Night Chart, Moon is the Sect Ruler of Earth Signs and so Venus and Moon would each have two dignities.
In that case, which one, Moon or Venus aspects that point? The one that does is the Almuten. If neither aspect it, or they are equally close in aspect, then take the one that is in the correct facing, and if neither are, then take the one that is closer in degrees.
Sometimes you have multiple points, like the Almuten of Marriage. That is the Planet that rules the Lot of Marriage, Venus, and the Sun for women or Moon for men. The Planet that has the greatest Dignity in those three points is the Planet that actually rules marriage in that chart, and so when you did your Profections and Solar Returns, you would be looking at the Almuten of Marriage to give you hints that marriage is possible, then you would look at Primary Directions (using the Almuten) to determine the exact date (since transits are guaranteed to fail).
Ptolemy says the quadrant the Almuten is located will tell you roughly when in life someone will gain/lose wealth, and directed the any Planet that afflicts the Almuten of Wealth will tell you when they'll lose it.
Others of the Hellenistic group, the Romans, Persians and some of the Medieval ones use the Almuten of the 2nd House cusp, Ruler 2nd House, Jupiter (the general significator of wealth), and the Lot of Wealth (aka Lot of Substance or Lot of Possessions) which is ASC + 2nd House Cusp - 2nd House Ruler.
From that point they follow Ptolemy. Really important are Planets that afflict the Almuten of Wealth and from where. For example, a square, is it ten Houses away (a Dexter square) or four Houses away (a Sinister square). Dexter aspects (Dexter sextiles, trines and squares are more powerful than Sinister sextiles, trines and squares), and also is the Planet that squares (or opposes) the Almuten Angular or elevated above the Almuten.
The Almuten will give you hints at how you acquire whatever wealth you might get, through your own labor, through inheritance, through luck, through your own wit and cunning and skill, through arts and crafts and other Venusian things and so on, through leadership and command ability (like running your own business or running someone else's business) or other Martian things and so on.
That method is much better than Ptolemy's (who had a peculiar bias against Greek Lots) and when you start looking at a lot of charts, you'll see that the Lot of Fortune has little to do with wealth, rather it is about the Native's general fortune in life and the good and bad that happens to them.
Another method that is not as complex but worth the effort is that of the later Medievals, like Bonatti and Lily.
Here, you're looking at the the area 5° before the 2nd House Cusp up to 5° before the 3rd House Cusp. You consider any Planets in the region, plus the 2nd House Ruler and the Planet that rules any intercepted Sign in the region. So if the 2nd House Cusp is 15° Taurus and the 3rd House Cusp is 22° Gemini, you'd be looking at the region between 10° Taurus in the 1st House up to 17° Gemini and you'd look at both Venus and Mercury who rule Taurus and Gemini, plus any Planets in that region.
They also want you to look at Jupiter and the Lot of Fortune and any Planets that aspect Jupiter or the Lot of Fortune.
They pay more attention to the condition of the Planets, so, for example Jupiter as the general significator of wealth should be Angular, Direct, in Dignity, preferably in Sagittarius, Pisces, or Cancer and if not then in his own Triplicity or Term, Oriental, Diurnal and not in square or opposition to Mercury, Sun, Mars or Saturn and not Combust (and that's true for any Planet).
What you don't want to see is Jupiter in Capricorn, Gemini or Virgo, or Retrograde or Peregrine, Combust, Cadent, Occidental, Nocturnal in a Day Chart or other things like that, and especially not in square or opposition to a Malefic or Accidental Malefic (like Sun or Mercury).
