I want to trade google stock and I want to run a test against it since they went public in 2004. When I try to trade using
context.symbol('GOOG') The backtest crunches my timeline down to the end of 2014 to today. I understand why it does that but I want to work around the fact that they did a stock split and then a name change. With their stock changing so much, how do we track it since it went public?
Hi Aaron,
It sounds like you are looking for the sid() method. This will give you a reference to the GOOG stock that persists through the ticker change. Check out this video for an explanation + example (for reference, that video is posted along with a few others here).
