Anchor percantages

When using an anchor in a chart I anchor at the open. The percentages of up and down don't match what I see on the portfolio screen.  That is true for indexes and stocks.in the specific case I am using XBI chart with AVXL and $DJI as compare symbol indicators.  I show AVXL on the portfolio and being down 1.95% and on the compare line i show it being down 2.84%XBI is sown 2.58% on the portfolio line and the chart shows it down 1.93%.

To set the anchor I narrow the chart display window to very small so the anchor line can be accurately placed on the 9:30 open.

are you comparing to CHANGE or Change from Open?

and did you compare the official OPEN value to the values on the chart? (they are not always the same)

 

[Tcarey]

If by change you mean the change column in the portfolio, I'm using change % and comparing that % to the anchored intra day chart using compare percentages that show up on the right side of the intraday chart. 

If I understand what you are suggesting the chart doesn't use the opening trade as an anchor but uses the closing value of the first minute of trading as its anchor value.

Is that correct?

[Jerry Medved]

no, change % uses previous close.  chart as you described is from Open, which may not be the same

[Tcarey]

Thx. What would be the best approach to have them report the same %?

Move the anchor?

[Jerry Medved]

you can try comparing to the Change from Open column. there is no option for anchor on prev close
