Exact SelectedValue on all Charts

Hello! I am working with multiple timeframes that are open across multiple charts. The following code selects the High on one of the charts for example and draws a horizontal line of this price on all charts.

However, on smaller timeframes, I have to zoom out to see the correct point, which for example happens when working with daily and 30min sheets. Is there a way not having to zoom out?

SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%), {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) )));
Plot( C, "Close", ParamColor("Color", colorDefault ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() ); 

reward_point = SelectedValue(High);
Plot(reward_point, "Target", ColorRGB(255, 153, 255),styleDashed );
