Calculating TenkanSen an KijunSen (Conversion line and Base line) in Ichimoku indicator using JavaScrpit

We have set of data for each period (such as daily including today and days before) that consists of 4 data, open, lowest, highest and close. TenkanSen is a number that is calculated by adding highest high between last 9 periods to their lower low divided by 2. and the number of periods to calculate for KijunSen is 26.

The information history is in the following format: [ih].[n].PriceMax for highest price and n is the number of days (before) so we know that [ih].[0].PriceMax is the highest from yesterday. Lowest uses [ih].[n].PriceMin and do the math yourself!

Now that the 9 periods high is between [ih].[0].PriceMax to [ih].[8].PriceMax for TenkanSen, and [ih].[0].PriceMax to [ih].[25].PriceMax for KijunSen, how can we calculate TenkanSen an KijunSen?

I used this

var TenkanSenMin = ([ih][0].PriceMin+ [ih][1].PriceMin+ [ih][2].PriceMin+ [ih][3].PriceMin+ [ih][4].PriceMin+ [ih][5].PriceMin+ [ih][6].PriceMin+ [ih][7].PriceMin+ [ih][8].PriceMin)/9


var TenkanSenMax = ([ih][0].PriceMax+ [ih][1].PriceMax+ [ih][2].PriceMax+ [ih][3].PriceMax+ [ih][4].PriceMax+ [ih][5].PriceMax+ [ih][6].PriceMax+ [ih][7].PriceMax+ [ih][8].PriceMax)/9

var TenkanSen = (TenkanSenMin + TenkanSenMax) / 2;

var KijunSenMin = ([ih][0].PriceMin+ [ih][1].PriceMin+ [ih][2].PriceMin+ [ih][3].PriceMin+ [ih][4].PriceMin+ [ih][5].PriceMin+ [ih][6].PriceMin+ [ih][7].PriceMin+ [ih][8].PriceMin+ [ih][9].PriceMin+ [ih][10].PriceMin+ [ih][11].PriceMin+ [ih][12].PriceMin+ [ih][13].PriceMin+ [ih][14].PriceMin+ [ih][15].PriceMin+ [ih][16].PriceMin+ [ih][17].PriceMin+ [ih][18].PriceMin+ [ih][19].PriceMin+ [ih][20].PriceMin+ [ih][21].PriceMin+ [ih][22].PriceMin+ [ih][23].PriceMin+ [ih][24].PriceMin+ [ih][25].PriceMin)/26


var KijunSenMax =([ih][0].PriceMax+ [ih][1].PriceMax+ [ih][2].PriceMax+ [ih][3].PriceMax+ [ih][4].PriceMax+ [ih][5].PriceMax+ [ih][6].PriceMax+ [ih][7].PriceMax+ [ih][8].PriceMax+ [ih][9].PriceMax+ [ih][10].PriceMax+ [ih][11].PriceMax+ [ih][12].PriceMax+ [ih][13].PriceMax+ [ih][14].PriceMax+ [ih][15].PriceMax+ [ih][16].PriceMax+ [ih][17].PriceMax+ ([ih][18].PriceMax)+ [ih][19].PriceMax+ [ih][20].PriceMax+ [ih][21].PriceMax+ [ih][22].PriceMax+ [ih][23].PriceMax+ [ih][24].PriceMax+ [ih][25].PriceMax)/26

var KijunSen = (KijunSenMin + KijunSenMax) / 2;
Solution

  • Use this simple math code:

    var TenkanSenMin = Math.min([ih][0].PriceMin, [ih][1].PriceMin, [ih][2].PriceMin, [ih][3].PriceMin, [ih][4].PriceMin, [ih][5].PriceMin, [ih][6].PriceMin, [ih][7].PriceMin, [ih][8].PriceMin)


var TenkanSenMax = Math.max([ih][0].PriceMax, [ih][1].PriceMax, [ih][2].PriceMax, [ih][3].PriceMax, [ih][4].PriceMax, [ih][5].PriceMax, [ih][6].PriceMax, [ih][7].PriceMax, [ih][8].PriceMax)

var TenkanSen = (TenkanSenMin + TenkanSenMax) / 2;

var KijunSenMin = Math.min([ih][0].PriceMin, [ih][1].PriceMin, [ih][2].PriceMin, [ih][3].PriceMin, [ih][4].PriceMin, [ih][5].PriceMin, [ih][6].PriceMin, [ih][7].PriceMin, [ih][8].PriceMin, [ih][9].PriceMin, [ih][10].PriceMin, [ih][11].PriceMin, [ih][12].PriceMin, [ih][13].PriceMin, [ih][14].PriceMin, [ih][15].PriceMin, [ih][16].PriceMin, [ih][17].PriceMin, [ih][18].PriceMin, [ih][19].PriceMin, [ih][20].PriceMin, [ih][21].PriceMin, [ih][22].PriceMin, [ih][23].PriceMin, [ih][24].PriceMin, [ih][25].PriceMin)


var KijunSenMax = Math.max([ih][0].PriceMax, [ih][1].PriceMax, [ih][2].PriceMax, [ih][3].PriceMax, [ih][4].PriceMax, [ih][5].PriceMax, [ih][6].PriceMax, [ih][7].PriceMax, [ih][8].PriceMax, [ih][9].PriceMax, [ih][10].PriceMax, [ih][11].PriceMax, [ih][12].PriceMax, [ih][13].PriceMax, [ih][14].PriceMax, [ih][15].PriceMax, [ih][16].PriceMax, [ih][17].PriceMax, ([ih][18].PriceMax), [ih][19].PriceMax, [ih][20].PriceMax, [ih][21].PriceMax, [ih][22].PriceMax, [ih][23].PriceMax, [ih][24].PriceMax, [ih][25].PriceMax)

var KijunSen = (KijunSenMin + KijunSenMax) / 2;
