We held a Retirement Seminar for dentists at our office recently. This being part a good ongoing series of educational talks and workshops to several groups of dentists in the north, and which also takes us to North Wales still.


If you are conversant with technical analysis, and use indicators such as the RSI or stochastic. You know one the unique reasons for having the BB's mainly because are placed directly on the stock chart. They are viewed in the context of regularly price movements. In fact, for me, they define the stock chart. Stock charts tell me way more about future movement using the BB placed with them. I rarely do any analysis without them, except for perhaps an initial viewing of a stock chart I am considering for watch list placement. BB's therefore do not give you a number, like alot of indicators, they don't tell you an overbought or oversold condition. They just provide a visual, a story, of where a stock has been. Therefor you have to interpret.


In the case of discrete data the minimum sample n required to estimate a proportion with a 95% confidence can be calculated using pursuing formula. As with continuous data we specify the confidence interval d, along with discrete data it's a really /- percentage point spread into the proportion we are estimating, thus n = ((2/d)^2)(p)(1-p).


Trading frequency is not linked to profitability, so trade valid time frames and suggests either potential trend following or swing trading. Leave day trading alone if you want to lose quickly.


Secondly, 1% of the typical market capitalization traded each day for tackled . year had to be at least $1,000. While there are extensive thinly-traded penny stocks that trade in a channeling pattern, it very hard come up with a profit on these stocks after taking into account the trading fees.


Suppose you are a random sample of 100 4th graders (how to do that would be for another article). You can take the mean, the how to calculate standard deviation in excel, and so on, separate will be true just for your routine. It won't exactly match the numbers for magnitude population - but we want to manage to say something this population, and, thanks to statistics, turn out to be. If we possess a random sample, we can calculate a confidence interval around the mean, and reasonably sure that the mean of the sum of population will be that confidence interval.


Identifying a trending market with Bollinger bands is very simple. Generally if the market is trending up, price will walk over the upper music band. If the industry is trending down, price will walk for the lower strip.


Consider the case of people buying various quantities of milk in a mall taking 10 at a the time. 5 people buy 2 gallons of milk, 2 buy 1 gallon, 2 buy 3 gallon and 1 buy 5 gallons of milk. What could be of milk that was purchased more? It is 2 gallon. Such measure is called mode(the most common value).
