Hi, everyone I am a beginner for option market. I am trying to find some options and stocks historical data for analyzing, but it seems difficult to find free historical data. I am here for asking help. Option SPY is selected to be my first invested target. For this reason, I need to have SPY's option and stock historical data at least 3 years. Both of two historical datas, we just need end of day. The historical data of stock SPY must have the information such as, date, open, lowest, highest and close price, etc. The historical data of Option SPY must have the information such as, strike price, open, highest, lowest, close price, volumn and open interest, etc. Examples for the option historical data : strike_price, open, highest, lowest, close, volumn, OpInt. 201, 2, 3.2, 0.8, 2.6, 25165, 67219 201.5, 2, 3.2, 0.8, 2.6, 25165, 67219 202, 2, 3.2, 0.8, 2.6, 25165, 67219 These historical data are used to analyze for finding a trading strategy. Can anyone tell me where to find the free historical data? Many thanks.
