I'm trying to use the Heatmap.c from the Financial Hacker blog but apparently I'm missing an #include? Which one? I tried hard finding it in the manual but unsuccessful ...

ZorroS 1.46 keeps telling me 'annual' undeclared identifier.

So far I have added

#include <default.c>
#include <profile.c>

the latter was required to declare plotHeatmap().

Have you used the script from the 2016 zip archive? The codes in the article are not the complete script, but only the essential part.

Aahh - I should have read the full article first, the hint to the 2016 script repository is at the very bottom. Now it works perfectly fine, thanks!
