There is one (and only one) strand of scientific theory that gives astro trading credibility (astro traders typically operate without reference to science or logical reasoning, and more on faith, which doesn’t sit well with me), namely that planetary alignment influences solar activity (which in turn influences the financial markets through sunspots and geomagnetism), so is there any evidence for this?
Yes, there is. There is a close relationship between the alignment of Venus, Earth and Jupiter, and solar activity cycles. Here it is in chart form from two different studies:

Essentially, the most aligned days between these 3 planets correlate very well with solar cycles, suggesting these tidal planets are the key driver of the sun’s known 11-year cycle of activity. NOTE: only these three tidal planets are found to be infuential, not other planets. So astro traders drawing on Mars or Saturn, for instance, do not have this scientific backing.
Now here are just a couple of my own multiple charts which provide evidence of the correlation between solar activity and the financial markets.
Astro traders who forecast the financial markets by considering constellations of Jupiter, Venus and Earth potentially are one step back in the process compared to my own assessment of sunspots and geomagnetism, HOWEVER this depends on their method (whether or not they are considering most aligned days between these three planets, or other configurations or drawing in other planets).
Do we need to go this one step further back? Well, we can predict the sunspot cycle fairly reliably without having to calculate planetary alignment (NASA forecast this) and we know the next peak should occur around Feb/March 2013. We can also predict geomagnetism using a space weather forecast up to 3 weeks out, and we can model it further out using historic seasonal geomagnetism. It is therefore questionnable what additional predictiveness planetary calculations can offer.
In summary, there is evidence to link together the alignment of Jupiter, Venus and the Earth with the sun’s activity cycle and the financial markets. There is a lack of evidence for other planets being influential. If predicting using sunspots and geomagnetism forecasts is one stage back, then predicting using most aligned days of those three planets is one stage further back, however it is questionnable what additional benefit this offers.
