writing error in "chuck_csv_data"

[tchang730]

I am new to Python. Tried the code under Jupyter notebook for few days but encounter a strange issue. When executing till "chuck_csv_data" which copy stock price to column C of MomentumCalc, it seems get wrong "index" of data point at some place. See below from my test--print-out (run code on 7/1/2020).

• Data point 109 is the 1st one: index should be 109 but it got index as 12.
• Date point 113 is 2nd one: index should be 113 but it got index as 4. There are more index of data point were wrong. Can you help check? thx

But executing "import_date" which create date info to column B of MomentumCalc, the index is correct

I think this is a logical bug of "chuck_csv_data": if price of multiple different date are same, it will only write to the 1st date for multiple time while other date will have no price info. Above data point 12 and data point 109 have same price.
