52 week high Explain the difference between these 2

soundmanshane · 2019-12-15T23:26:47+00:00

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?

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])
```
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]
```
