Plot Only For Specific Symbols

Whistler

New member
I've programmed in Tradestation EasyLanguage for 25 years, but am finding it very difficult to transfer over to ThinkScript. I'm trying to plot a line only for certain symbols. I'm sure that there are several syntax errors in my code, but I can't figure out what should work. Can anyone help?

Code:
if GetSymbol() == "/ES"
then
{   plot Line01= 4590;
    Line01.SetDefaultColor(Color.RED);
    Line01.SetLineWeight(2);
    plot Line02= 4560;
    Line02.SetDefaultColor(Color.WHITE);
    Line02.SetLineWeight(1);}
else Double.NaN;
 
Solution
Thank you. This compiles just fine and seems to work with stock symbols, but not with futures symbols. Would you happen to know why it isn't working with futures symbols?

Ruby:
plot Line01 = if  GetSymbol() == "/ES:XCME" then 4600 else double.nan;
Line01.SetDefaultColor(Color.RED);
Line01.SetLineWeight(2);

plot Line02 = if  GetSymbol() == "/ES:XCME" then 4500 else double.nan;
Line02.SetDefaultColor(Color.WHITE);
Line02.SetLineWeight(1);

can't put plot functions within a script function or if-then.
try using an if-then formula, for the plot formula, to test for a valid value.

Code:
plot Line01= if (GetSymbol() == "/ES" then 4590 else double.nan;
    Line01.SetDefaultColor(Color.RED);
    Line01.SetLineWeight(2);

plot Line02 = if (GetSymbol() == "/ES") then 4560 else double.nan;
    Line02.SetDefaultColor(Color.WHITE);
    Line02.SetLineWeight(1);

I'm trying to get the following label to display the info specifically for "SPY" regardless of what ticker I am currently looking at on the chart. Line #1 works by adding ("SPY") after VWAP. However, I've tried adding ("SPY") everywhere possible in line #2, but that does not work. Any suggestions?

Code:
def s =  VWAP("SPY");
def s2 = reference MACD("fast length" = 6)."Value";

def Bullish = if s is greater than s from 1 bar ago and s2 is greater than s2 from 1 bar ago then yes else no;
def Bearish = if s is less than s from 1 bar ago and s2 is less than s2 from 1 bar ago then yes else no;

def Neutral1 = if s is less than s from 1 bar ago and s2 is greater than s2 from 1 bar ago then yes else no;
def Neutral2 = if s is greater than s from 1 bar ago and s2 is less than s2 from 1 bar ago then yes else no;

AddLabel(yes,if bullish then "RISING" else  "", if bullish then color.green else color.white);
AddLabel(yes,if bearish then "FALLING" else  "", if bearish then color.light_red else color.white);
AddLabel(yes,if neutral1 then "NEUTRAL" else  "", if neutral1 then color.gray else color.white);
AddLabel(yes,if neutral2 then "NEUTRAL" else  "", if neutral2 then color.gray else color.white);
