The last notes



    Is supply increasing each time we make a new push to a high? The information provided by rusrock-leg.ru, Inc. Which one is for you we cannot say, as it is really a matter of what you are comfortable with. In the image you will notice two key points: Now that we have addressed the issue with the Standard Deviation formula being used in the Bollinger Band calculation, we can create a new improved Bollinger Band indicator using the new formula. Though most investors use standard deviation to determine volatility, there's an easier and more accurate way of doing it. Taking the first difference, however, yields these summary statistics:.




    All you had to do was multiply the average by one plus the desired percent to get the upper band or divide by one plus the desired percent to get the lower band, which was a computationally easy idea at a time when computation was either time consuming or costly. This was the day of columnar pads, adding machines and pencils, and for the lucky, mechanical calculators.

    Naturally market timers and stock pickers quickly took up the idea as it gave them access to definitions of high and low they banss use in their timing operations. Oscillators were caculate much in vogue at the time and this lead to a number of systems comparing the action of price within percent bands to oscillator action. Tags of the upper band accompanied by negative oscillator readings from either oscillator were taken as sell signals.

    Buy signals were generated by tags of the lower band accompanied by positive oscillator readings from either oscillator. Coincident readings from both oscillators served to increase confidence. This approach and a myriad of variants remain calculwte use today as useful timing guides. Many modifications to this approach are possible and many have been made. A departure graph is a graph of the difference of two cslculate, a short-term average and a long-term average.

    The plot tl of the short-term average minus the long-term average. The prime benefit of using the departure technique to create the oscillators is that the use of the long-term moving average has the effect banrs adjusting normalizing for long-term biases in market. Without this adjustment t simple Advance-Decline oscillator or Up Volume-Down Volume oscillator will likely fool you from time to time. Bollinger bands how to calculate, using the difference between averages very nicely adjusts for the bullish or bollinger bands how to calculate biases that bollinger bands how to calculate the problem.

    Yow the valculate technique also means that you can use the widely available MACD calculation to create the oscillators. The data inputs are advances-declines and up volume-down volume. Now substitute Bollinger Bands for the percentage bands and you have the core of a very useful reversal system for timing markets. In a similar vein we can use indicators to clarify tops and bottoms and confirm reversals in trend. The logic at tops is similar, but we need to be more patient.

    As is typical, the top takes longer and usually presents the classic three or more pushes to a high. After such a pattern develops look at selling meaningful down days where volume and range are greater than average. What we are doing in Method III is clarifying tops and bottoms by involving an independent variable, volume in our analysis via the use of volume bolllinger to help get a better picture of the shifting nature of supply and demand.

    Is demand increasing across a W bottom? If so, we ought to be interested in buying. Is supply increasing each time we make a new push to a high? Hoow so, we ought to be marshalling our defenses or thinking about shorting if so inclined. The bottom line here is clarification of patterns that are otherwise interesting, but on which you might not have the confidence to act without corroboration.
