Add multiple lines and bubbles to chart

The lines you requested were provided in the previous post I found using the search function:

So all we need to do is add the chart bubbles. Given my example, you can work out how to add whoever many lines and chart bubbles you want to display.

Here is the code from the solution I linked above:

input plusPercent = 20.0;
input minusPercent= 20.0;
def prevDailyClose = close(period = AggregationPeriod.DAY)[1];
plot upper = prevDailyClose * (1 + (plusPercent * 0.01));
plot lower = prevDailyClose * (1 - (minusPercent * 0.01));

To add the chart bubbles to this we must first assume that you intended to place those chart bubbles on the last bar of the chart.

Here is the new section of code which adds the chart bubbles to the last bar of each of the lines plotted on the chart:

input plusPercent = 20.0;
input minusPercent= 20.0;
def prevDailyClose = close(period = AggregationPeriod.DAY)[1];
plot upper = prevDailyClose * (1 + (plusPercent * 0.01));
plot lower = prevDailyClose * (1 - (minusPercent * 0.01));
def lastBar = IsNaN(close[-1]) and !IsNaN(close);
AddChartBubble(lastBar, upper, upper, upper.TakeValueColor(), yes);
AddChartBubble(lastBar, lower, lower, lower.TakeValueColor(), no);
