Replace:
for i in range(1, 31):
with:
for d in Data[1:31]: #since you have range(1,31). Do Data[1:] if you just want to skip the first
OneDate.append(d[0])
OneClose.append(d[4])
This usually happends when Data
array has less than 31 indices. Also ensure d
array has atleast 5 items, else d[4]
will also throw a similar error. Use:
if len(d) >= 5: #check first.
OneDate.append(d[0])
OneClose.append(d[4])
