      Most of the time, the vast majority of technical indicators are aboutas useful as flipping a coin. However, depending upon the security beinganalyzed, the sector that the security falls into, and the nature of theoverall market, some technicals can be accurate predictors of pricemovement. Obviously there is no technical indicator that will perfectlypredict future price movements. If there was one, the inventor wouldcertainly never share it with anyone. Therefore, when considering theeffectiveness of a particular technical indicator, it is helpful to thinkin terms of "probability of success."Any technical indicator exhibiting aprobability of success greater than 50 percent is a useful tool (at leastmore so than your average coin).
