I've been looking into pair trading and am trying to create a chart of the ratio between two stocks for pair trading.
I have been able to create the chart by using parameters to set the two stock tickers but I'd like to save a list of these and be able to call them up one and a time like regular stocks. What I have done is create symbols which contain both tickers separated by a character. In other words, if I want to plot the ratio of POT to MOS I have created a symbol called POT^MOS. Then I have put the following code into an indicator where i pull up the ticker, split into two symbols and try to plot the ratio. Ticker=Name(); Ticklen= strlen(ticker); Spot = strfind(ticker,"^"); Tick1 = strleft(ticker,spot-1); Tick2 = strright(ticker,ticklen-spot); C1 = foreign(tick1,"C"); C2 = foreign(tick2,"C"); Ratio = c1/c2; Plot(ratio,"ratio",colorgreen,styleline); When I move to this special ticker the normal price chart is blank (because there is no real ticker called POT^MOS) so the normal price is empty because close is empty. But, I can not get anything to display in this indicator box either. Should I be able to do this? Does my code look ok for this?
