  • Berkshire Ratio Indicator ThinkorSwim Code 2 comments
    Feb 5, 2014 1:31 PM | about stocks: BRK.B

    For those that have thinkorswim, here is the code for my Berkshire ratio indicator, indicator value of 7 is a buy point. Enjoy!

    Declare Lower;

    input length = 50;

    def Vol = volume;

    def VolAvg = Average(volume, length);

    Def A = close;

    Def B = close("BRK/B");

    def V = close("VIX");

    def Spread=(A/B);

    Plot ind= if(spread>1510,1,0)+if(v>v[1],1,0)+if(close<open,1,0)+if((vol>volavg*2),1,0)+if(volume>volume[1],1,0)+if(low<low[1],1,0)+if(high<high[1],1,0);

    I don't use thinkorswim and I have limited programming experience but there seems to be something missing in your code.
    Def A = close.
    Did you mean Def A = close("BRK/A")?
    I don't know the details of your strategy--- are you arbitraging price differences between BRK.A and BRK.B? Have you backtested the strategy and if so how has it performed?

    Author’s reply » I have an article pending that explains what I'm doing. Yeah you could put close("BRK/A") or just when viewing the study have BRK/A as the stock you are looking at.
