Title: Re: [amibroker] Re: Trading Research and its Statistics
Hello,
fwiw, streaks are easier calculated using Sum(), this also allows placing the AddColumns() in a loop for n (Plots for testing only):
Day10Dn=C < Ref(C,-1) AND Ref(C,-1)< Ref(C,-2)AND Ref(C,-2)< Ref(C,-3)AND
Ref(C,-3) < Ref(C,-4)AND Ref(C,-4) < Ref(C,-5)AND Ref(C,-5)< Ref(C,-6)AND
Ref(C,-6) < Ref(C,-7)AND Ref(C,-7) < Ref(C,-8)AND Ref(C,-8) < Ref(C,-9) AND
Ref(C,-9) < Ref(C,-10);
// shorter method:
n = 10;
Day10Dn = Sum(C<Ref(C,-1),n)==n;
Best regards,
herman

That's a nice exploration.
For anyone interested, I've extended it to provide parameterized colors on the output columns here .
