Proposed solution
```python
class Solution:
def maxActiveSectionsAfterTrade(self, s: str) -> int:
s = '1' + s + '1'
n = len(s) - 2
max_active = 0
i = 0
while i < n:

start = i
while i < n and s[i] == '1':
i += 1
end = i
while i < n and s[i] == '0':
i += 1
max_active = max(max_active, end - start + 1)
else:
i += 1
return max_active
