Calculate indicator without after hours data on a chart with after hours data in ThinkOrSwim


New member
Is there any conceivable way to calculate on indictor without after hours data on a chart with after hours data?

Some indicators can benefit from using after hours data and others are messed up by it. For instance, knowing the after hours high and low can be valuable. So can knowing the trend leading into the cash session. However, after hours data messes up ATR calculations on intraday charts at the beginning of the day. It also messes up ADX. So what I'd like to do is look at a chart with the after hours data included but see an ATR or ADX calculated without the after hours data. It sounds kinda impossible to me but you guys come up with crazy solutions sometimes.
You could try a 2 chart grid as you cannot have (or very difficult to code, if possible) the ADX and ATR values without afterhours on a chart that is set to display afterhours. You lose some screen space with the grid, but it may be worth it to you to have the values as you wanted.

The upper chart in the image is set without afterhours, no price subgraph and the indicator moved to the lower pane of the chart.

The lower chart in the image is the same script as in the upper with afterhours displayed to show the differences as you indicated in the ADX and ATR.

addlabel(1, "ADX " + ADX(), color.white);
addlabel(1, "ATR " + ATR(), color.yellow);

That's brilliant! Not perfect, but functional. If only you could actually grab a label from another chart to populate on the current chart.
