Pairs trading issue

July 25th, 2014, 09:50 AM

Hello,

Please help me solve problem with thinkscript. I will be very grateful for help or any ideas.

Pair trading is my strategy. I would like to link 3 chart windows. First one I using for displaying pair chart (for example AAPL/MSFT). Second and third I using for displaying single charts (for example AAPL on second window and MSFT on third). I link all of these windows and would like to receive all charts by selecting only one pair in first window.

My problem that I can't find necessary thinkscript functional for ploting bar chart by symbol.

I write the next script:

Code

declare lower;
def value = close(GetSymbolPart(1)) / close(GetSymbolPart(2));
def isInverted = if value > 1 then no else yes;
def tickerIndex = if isInverted then 1 else 2;
plot chart = close(GetSymbolPart(tickerIndex));

But this script plots only close line. I would like to plot bar chart. Is it possible? Or maybe exists some unique charts linking method in thinkorswim software?

Thank you so much!

Not sure if this is what you are trying to do, but there is a link chart button to the right of the symbol input area:

Edit: I re-read what you wrote and I don't think there is a way to link a pair chart to make it split into the two separate symbols. The pair symbol is read as 1 symbol.
