I was kind of looking forward to Tomasz'z response to this - it would have been classic. But, it looks like he is doing other things. So, I'll offer one quick observation while I'm here.
There are many speed-up opportunities available for a 123 ticker cross correlation app. But, the first is obvious. The matrix is TRIANGULAR. If that doesn't ring a bell, Wiki it. But the bottom line is that N*N calculations are not need. Assuming 1 for the diagonal N*(N-1)/2 calculations are enough - approximately 1/2. So, this will cut your time considerable and there are some other things such as SetBarsRequired() that will help also. But your are still calculating a lot of results and targets of fractions of a second are probably not realistic. --- In [email protected], "gmorlosky" <gmorlo...@...> wrote: > > Thanks - So I am really doing 123 * 123 in the orginal example...

This particular indicator code (HeatMap of 123 symbols)runs like a dog (5 seconds or more to complete. I have no plugins or scripting. The details of each function are below.
