Getting Clear With Short-Term Swings by Ron Black
Does an indicator that works on all time frames, requires no calculation, and has no delay sound too good to be true? Itís not.
The technicianís unending task is to find a signal in a sea of data. Price patterns can be choppy, chaotic, and wiggly. Sometimes the technician tries to smooth the upward and downward surges in price action in order to make the price movement easier to interpret. But this smoothing can reduce his or her indicatorsí sensitivity to the immediate direction of the price.
The Clear method, a new technique for identifying the direction of short-term price swings, identifies the direction of the current price swing and the precise day when price direction changes. It works on all time frames, requires no calculation, and has no delay. It is applicable to all stocks, commodities, and indexes. The Clear method is unique because, unlike most technical indicators, it does not use the opening price or the closing price. Instead, it uses the range (length) of the price bar. It is effective because it borrows from a basic statistical concept: if two distributions do not overlap, they can be considered different.
(A note to our statistician friends: this paper is not intended to examine the subtleties of sampling errors, sample size, covariance, confidence intervals, or any other statistical description. I am merely adapting a statistical concept for the purpose of analyzing price action.)
Letís begin with a short description of distributions. What if someone asked you, ďHow fast do cars go on the freeway?Ē You are analytical. You want to find the answer. You rent a radar gun and a tripod, set the equipment up on an overpass, and record the speed of every vehicle that passes beneath the overpass for the next hour. Obviously, you would get many different values for the speeds of the different vehicles that traveled under the overpass.
