A clear explanation of forming the Gold’s bottom :
In a closer view on these frames of intra-day charts, After a leading diagonal as the first wave of wave (v), Gold extended the third waves of wave (v), then has formed a triangle fourth-wave. Currently, the latest fifth wave of the extended sequence will likely be ahead.
Green idea : A leading diagonal, as a directional initial concept, conceptually could suggest to extend the following waves.
Note : I’ve presently shifted to the same first alternative.
