Volume-Up/Down - Bolton-Tremblay Indicator
At this point, two other representatives will be presented from the group of indicators of anticipated decline. The beginning must be made with the Volume-Up/Down that uses the volume of shares traded on the rise and fall in a market as a base. The indicator consists of two different lines as a result, the index Up and Down volume index volume. The first indicates the volume measured values above, the last in the prices fell. The possible interpretation of Volume-Up/Down is almost obvious: If the Volume Down Volume Up above the selling pressure that prevails in other cases, the corresponding buying pressure. The intersection of two lines can be used for imminent change in trend as a possible clue.
Finally must be mentioned briefly Bolton-Tremblay Indicator, which forms the one and the same increase in the ratio of closing values of a market or index and the other one-off values and closing unchanged. In order to give the whole thing mathematical complexity, the values are subtracted, then take the square root of it. In the end, then there is a continuous summation of the values determined. Mathematically, this construction bold determined as follows:
AdAdv if (t)> AdDec (t)
BTI (t) = RTC (t-1) + sqrt ((AdAdv (t) / AdUcg (t)) - (AdDec (t) / AdUcg (t)))
BTI (t) = RTC (t-1) + sqrt (abs (AdAdv (t) / AdUcg (t)) - (AdDec (t) / AdUcg (t))))
That the interpretations or the input and output signals konkrrete are concerned, the principle is said to be linked to many representatives A / D.
