Reduce the work performed by the loop on each bar. Pine limits a single loop to 500 milliseconds, and a million-iteration sum can exceed that runtime budget even though it compiles. The same arithmetic series has a constant-time formula, so the fixed script removes the loop entirely. For nontrivial algorithms, shrink the search range, cache reusable values, or replace linear scans with bounded searches.
