   mask = [0,closing > opening,0];

Now have a look at

 find(mask(1:end-1) & ~mask(2:end))

This tells you about the end of streaks. You can likewise find the beginning of streaks. Each beginning has an end. You can figure out lengths by matching positions

how does this help with the problem I attached above? where would i enter this

[Walter Roberson]

Your task does not depend on how much gain is made, just that some gain is made. So you can calculate a vector of 1 (gain made) and 0 (not a gain ) and now the task is to find the place with the greatest streak of 1s.
