Pairs trading error message

Hi everybody,

I am trying to use the webinar in pairs trading with second-second data. I keep getting a error. I am using 1 day. If anybody could tell me how I can prevent the error it would be helpful.

INPUT

window = 120:60:420; freq = 10:10:60; range = {window, freq};

annualScaling = sqrt(250*7*60*60); cost = 0.01;

pfun = @(x) pairsFun(x, DZZGLLfull, annualScaling, cost);

tic [~,param] = parameterSweep(pfun,range); toc

pairs(ZZGLLfull, param(1), param(2), 1, annualScaling, cost)

OUTPUT

??? Error using ==> parallel_function at 598 Error in ==> adftest at 317 Effective sample size of the data is less than the minimum 10 in the table of critical values.

Error in ==> pairsFun at 19 parfor i = 1:row

Error in ==> @(x)pairsFun(x,DZZGLLfull,annualScaling,cost)

Error in ==> parameterSweep at 58 resp = fun(cell2mat(var));

I just watched the webinar as well, and I am getting the same error. Any suggestions on how to fix this?

cause the normalized sample has some NaN data, which makes the efficient length of the sample is less than the minimum 10
