Resistance level algorithm: resistance level = lowest price+{(front high and low point) *0.375} resistance level = lowest price+{(front high and low point) *0.5} resistance level = lowest price+{(front high and low point) *0.625} resistance level = lowest price+{(front high and low point) support level algorithm: support level The fourth resistance level = lowest price *1.809; Fifth resistance level = lowest price *2. The calculation formula of fulcrum is as follows: fulcrum = (highest price+lowest price+closing price) /3 support level 1=(2* fulcrum)-highest resistance level 1=(2* fulcrum)-lowest support level 2= fulcrum-(resistance level 1- support level 650. Calculation method of data perspective point. There are several ways to calculate the data perspective point, and the following 7-point calculation method is the most commonly used. This equation uses the highest point, lowest point and closing point of the previous day to calculate the pivotpoint position and three support positions. Three resistance levels R3 = h+2 * (p-l) R2 = p+(r1-s1) r1= (px2)-LP = (h+l+c)/3s1=
