How to overlay a line chart onto my candle chart...

[johnwood34]

Anyone know how to overlay a line chart onto a candle chart? I have two screens pulled up. One for a line chart and the other for a candle chart, but was wondering if anyone knows how to slap a line chart onto a candle chart. Or is there an indicator available?

Use the Comparison study and then change it to a Line chart.

can you shoot me a screenshot? i tried and couldnt get a line chart overlay to show up. Included a pic of what im looking at...

Comparison study:
1) Change comparison style to LINE
2)Change secondary security to NVDA
3) Optional: change Color

This comparison study has more functionality/user-controlled settings available:

def NVDA = close("NVDA");
def symbol = NVDA;

plot s = symbol;
s.DefineColor("Up", GetColor(6));
s.DefineColor("Down", GetColor(5));
s.AssignValueColor(if s > s[1] then s.Color("Up") else s.Color("Down"));
s.SetLineWeight(1);
s.SetStyle(1);
s.HideBubble();
s.HideTitle();

Thank you for both of those responses! Exactly what i needed. Maybe it's OnDemand but i tried the comparison study twice last night but nothing would plot...

Curious as to whether or not this script can be adjusted to, rather than the closes of each candle being attached to the previous, tie each high and low to the previous...

vague questions like this is why i rewrite rules, and sometimes ask a person to rethink and rewrite.
when you say line chart, what are you really asking for? a line connecting the close price on each bar.

this is a programming site, so my 1st thought is a study.
and what study does this?
the default one that shows up when you create a study.

plot Data = close;

They could also use a MA as well I suppose. MA period =1

Thanks for this @halcyonguy. I often find myself overcomplicating issues by not rethinking what I am really asking the script to do. I start with the image I think I want rather than asking myself what am I asking the script to do. I should spend more time thinking/analyzing and less time typing disjunctured code.

This is what i was looking for...

def isGreen = close > open;
def isRed = close < open;

# We create a series that holds the value to plot:
# For green candle, use high
# For red candle, use low
# If candle is doji (close == open), we carry forward previous value

def plotValue = if isGreen then high else if isRed then low else Double.NaN;

# Because we want to connect points sequentially, fill in NaNs by previous value to avoid breaks
rec filledPlotValue = if !IsNaN(plotValue) then plotValue else filledPlotValue[1];

plot connectingLine = filledPlotValue;
connectingLine.SetDefaultColor(Color.CYAN);
connectingLine.SetLineWeight(2);
connectingLine.SetStyle(Curve.FIRM);
connectingLine.HideBubble();
connectingLine.HideTitle();
