Triple top and triple bottom Triple top and triple bottom Triple top and triple bottom are reversal chart patterns used in the technical analysis of stocks, commodites, currencies, and other assets. Formation The formation of triple tops is rarer than that of double tops in the rising market trend. The volume is usually low during the second rally up and lesser during the formation of the "third top." The peaks may not necessarily be spaced evenly like those which constitute a Double top. The intervening valleys may not bottom out at exactly the same level, i.e. either the first or second may be lower. The
Quadruple product Quadruple product In mathematics, the quadruple product is a product of four vectors in three-dimensional Euclidean space. The name "quadruple product" is used for two different products, the scalar-valued scalar quadruple product and the vector-valued vector quadruple product or vector product of four vectors . The scalar quadruple product is defined as the dot product of two cross products: where a, b, c, d are vectors in three-dimensional Euclidean space. It can be evaluated using the identity: or using the determinant: The vector quadruple product is defined as the cross product of two cross products: where a, b, c, d
