Random article: Point and figure chart
When price reverses and passes a certain threshold value (amount is indicated in reversal parameters), then it is time to stop forming table of one type and switch to forming another. It can start from entering several crosses or noughts at once (if reversal exceeds 2)
Rendering the price in the form of this type of forex chart is not tied to time scale. Therefore, adjustment of many approaches to classical technical analysis is required. Crosses and noughts are convenient to render levels around which the price stops for a ling time (consolidation level).
