The analytical method of looking for buying signals is to wait for a solid trend break after the index has fallen through a considerable range. This can often indicate that the down trend has now ended. A down trend is often broken by a period of volatility in which the buying impetus more or less matches the decline in new sellers. This creates a set of mini or temporary upper and lower levels. As soon as the new upper level is tested and broken, buyers (going 'long') enter the market near the 'upside', causing a further rally, which may or may not be sustained.
A good general method that very often indicates a good time to buy into the major world stock markets is to purchase approximately 10 days leading into a fortunate aspect (trine, sextile and most conjunctions) between the Sun and Jupiter. There is invariably a noticeable degree of expansion in the markets during these days. Click here for a list of these dates.
The 'upside' of the volatility range varies according to the period and method used when calculating moving averages. Sometimes it is easy to see in an historical chart the increased buying activity as each 20, 30 or 50 Exponential Moving Average (EMA) line is reached, most likely due to the many traders all employing similar techniques and entering long trades, like sheep, at almost the same time.
If the trend is now up, the moving averages will rise to confirm this. At this stage, a trader will often set a stop at roughly the 20-day EMA. This offers a reasonable level of protection while at the same time allow a certain amount of volatility without unnecessarily closing the trade. Stop levels are highly subjective and a certain amount of gut-feel and experience is required to get the balance right.
The share prices of all the companies I've studied so far definitely move in accordance with transits and progressions to the date and time the company listed on the relevant stock exchange. If you can find out this date, by using an approximate birth-time (say 10am) and location, you will be able to follow a company's transits on the stock exchange. It definitely works, the most dramatic proof of this is noticeable when there are huge movements either way or if the company goes under.
An interesting excercise is to Google the ten most successful and unsuccessful websites. You can find the dates they began on the internet by using Whois. Look at the charts for those dates and you will invariably see the massive fortunate or unfortunate aspects under which they were born. Then, by progressing the charts (by adding a day for each year they were in operation), you will see how they perfomed, either rising to great success or failure. Look at both the progressed-to-natal aspects as well as the whole 'progressed geometry' of the future-dated charts. It works remarkably well. You can use this method to evaluate new startup sites and companies to gain valuable insights regarding how successful they may be. Alternatively, you should consider consulting the advice of a professional astrologer when starting your own company or ventures. Make sure that the houses involving your type of business are considered, the planets in them and the condition of the rulers. Try and start something when the moon is waxing, try and get some planets 'angular' and make sure you look at the progressions that take place in the ensuing years.
The best advice could be that, although technical methods of determining the approximate times at which you should buy currencies, securities or commodities are generally quite helpful, the underlying rule is that you will battle to make money speculatively if the planets are not favourably aspecting your natal chart during that period. Whenever you have made the decision to purchase anything substantial, it might be a good idea to use a transit program to check or confirm that you are making a wise choice.
