Good morning everyone
I saw a pairs trading webinar on the topic and found this code.
I can not understand these two pieces of code, anyone is kind enough to explain
% The strategy:
% 1 Compute residuals over next N days
res = series2 (i: i + N-1, 1) ...
- (Reg1.coeff (1) + reg1.coeff (2). * Series2 (i: i + N-1, 2));
% 2 If the residuals are large and positive, then the first series
% Is Likely to decline vs. the second series. Short the first
% Series by a scaled number of shares and long the second series by
1% share. If the residuals are large and negative, do the
% Opposite.
indicated (i: i + N-1) = res / reg1.RMSE;
s (i: i + N-1, 2) = (res / reg1.RMSE> spread) ...
- (Res / reg1.RMSE <-spread);
s (i: i + N-1, 1) = -reg1.coeff (2). * s (i: i + N-1, 2);
end
end
Thank you very much for your cooperation
ps do you know where I can find some code on the pairs trading?
