Looking to add a horizontal line for the 21 ema for daily, 1H, 2H and 4H that updates automatically in the chart. Can anyone help me? I’m using the thinkorswim platform and need a script to be able to add those to a single chart.

This has bubble option to assist display.

Thank you so much. Is there a way that it can be only a straight horizontal line?

Sure, with an option to have the lines only show on today or whole chart

Ruby:
input showtodayonly = yes;
def xemaD = if !IsNaN(close) and IsNaN(close[-1])
            then ExpAverage(close(period = AggregationPeriod.DAY), 21)
            else Double.NaN;
plot emaD = if showtodayonly and GetDay() != GetLastDay()
            then Double.NaN
            else HighestAll(xemaD);
emaD.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
def xema4 = if !IsNaN(close) and IsNaN(close[-1])
            then ExpAverage(close(period = AggregationPeriod.FOUR_HOURS), 21)
            else Double.NaN;
plot ema4 = if showtodayonly and GetDay() != GetLastDay()
            then Double.NaN
            else HighestAll(xema4);
ema4.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
def xema2 = if !IsNaN(close) and IsNaN(close[-1])
            then ExpAverage(close(period = AggregationPeriod.TWO_HOURS), 21)
            else Double.NaN;
plot ema2 = if showtodayonly and GetDay() != GetLastDay()
            then Double.NaN
            else HighestAll(xema2);
ema2.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
def xema1 = if !IsNaN(close) and IsNaN(close[-1])
            then ExpAverage(close(period = AggregationPeriod.HOUR), 21)

            then Double.NaN

input showbubbles = yes;

I have an issue. It's currently not showing on the 4HR or the Daily Chart. It only shows on the 1HR and 1min-45min

Since you have an 1hour timeframe in your script then it will not display on charts higher than 1hour. This applies to any script that contains higher aggregations.

You can make a new script removing the timeframes below 4hrs to display this on a 4hr chart both the 4hr and Daily timeframes . See below.

input showtodayonly = yes;
def xemaD = if !IsNaN(close) and IsNaN(close[-1])
            then ExpAverage(close(period = AggregationPeriod.DAY), 21)
            else Double.NaN;
plot emaD = if showtodayonly and GetDay() != GetLastDay()
            then Double.NaN
            else HighestAll(xemaD);
emaD.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);
def xema4 = if !IsNaN(close) and IsNaN(close[-1])
            then ExpAverage(close(period = AggregationPeriod.FOUR_HOURS), 21)
            else Double.NaN;
plot ema4 = if showtodayonly and GetDay() != GetLastDay()
            then Double.NaN
            else HighestAll(xema4);
ema4.SetPaintingStrategy(PaintingStrategy.HORIZONTAL);


input showbubbles = yes;
input bubblemover = 3;
def   bm = bubblemover;
def  bm1 = bm + 1;
AddChartBubble(showbubbles and IsNaN(close[bm]) and !IsNaN(close[bm1]),
               emaD[bm], "D", emaD.TakeValueColor());
AddChartBubble(showbubbles and IsNaN(close[bm]) and !IsNaN(close[bm1]),
               ema4[bm], "4", ema4.TakeValueColor());
