52 week high Explain the difference between these 2

  Hey,

   

  this is such a simple question but I am looking at some old coding of mine and notice 2 things I’ve put in differently

   

  HC = Highest [ 52 ] ( High ) [ 2 ]

  HC = Highest [ 52 ] ( High ) [ 1 ]

   

  What is the difference between the 1 and the 2, is it that the last 2 bars are high closes on the prevous 52 and the last 1 bar is a high close on the previous 52?

  Both find the highest high within the last 52 bars.

  The difference is that [1] starts from the 1st bar preceding the current one (which is none or [0]), while [2] starts from the 2nd bar preceding the current bar. [1] will scan bars 1-52, [2] will scan bars 2-53.

  They can also be written as:

  HC = Highest[52](High[2]) HC = Highest[52](High[1])

  1 2	HC = Highest[52](High[2]) HC = Highest[52](High[1])

  there’s no difference (only logic differs).

  This example fits best my explanation above.

  You examples scan 52 bars, but they retrieve the value that was retained 2 and 1 bars ago, respectively.

  You could accomplish the same goal with:

  HC = Highest[52](High) HCx = HC[2] // or HC = Highest[52](High) HCx = HC[1]

  1 2 3 4 5

  HC  = Highest[52](High) HCx = HC[2] //    or HC  = Highest[52](High) HCx = HC[1]
