How to make williams indicator update every 5 second in 1Minute chart

New comment

Usually, when we attach williams percent range indicator to a chart, say 1M chart it just draws and fixes the line per bar. But I want it to fix the line per 5 seconds. In another words, WPR updates the drawn line per bar, I want it to update per 5 seconds. (not 5 ticks, not 5 bars, just per 5 seconds)

It does not update "per bar". It is updating on tick (ie: when there is a change on price(s)) - it does not draw a fix line. Set the period to small value and you shall see much easier

Making it update each 5 second would not change anything regarding results since on timer a lot of time you would not have any price changed at all
