Using Lower Chart To Plot Arrows On Upper Chart

So I have some code that looks like this:

declare lower;

plot UpSignal = if c1 + c2 + c3 + c4 + c5 == 5 THEN 1 else Double.Nan;
UpSignal.SetDefaultColor(Color.GREEN);
UpSignal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);

The declare lower makes it so the arrows appear in the lower area. How can I plot the arrows on the chart itself like right under the bars for buy signals and above for sell signals?

Second question, is there a way to make it show the buy signal only if the status has changed? Like if the previous values are still a buy don't display another up arrow? So it doesn't display a line of buy arrows.

Hi everyone! Hope everyone is doing well.

plot UpSignal = if c1 + c2 + c3 + c4 + c5 == 5 THEN 1 else Double.Nan;

If you disable the declare lower statement, by putting a # in front of it, the arrows will appear on the upper chart.

Note: boolean plots may not work as expected in lower charts. they are plotted at the close price levels.

a lower study

# fivecond_booleanarrows_0
declare lower;
def c1 = close > close[1];
plot UpSignal = if c1 + c1[1] + c1[2] + c1[3] + c1[4] == 5 THEN 1 else Double.Nan;
UpSignal.SetDefaultColor(Color.GREEN);
UpSignal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
#

change it so the user can choose to show, all arrows or just the first one in each series.
disable the declare lower, to make it an upper study.

# fivecond_booleanarrows_0
#declare lower;
def c1 = close > close[1];
input show_just_first_arrow_of_series = yes;
def UpSignal = if c1 + c1[1] + c1[2] + c1[3] + c1[4] == 5 THEN 1 else 0;;
plot z = if !show_just_first_arrow_of_series then upsignal
  else if (!UpSignal[1] and UpSignal) then 1
  else 0;
z.SetDefaultColor(Color.GREEN);
z.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
#

Hi, thanks for the reply!

I do kind of need the declare lower statement because it's outputting a lot of other stuff too. I was wondering if there's a way to place just the arrows on the main chart?

It is not possible for the lower chart study to plot arrows on the upper chart.
@halcyonguy explained how to put a copy of the study in the upper chart to plot the arrows.
You would keep another copy of the original study for use in the lower chart.
