I have same indicator for multiple symbols.
I need to record indicator data for each symbol in rolling windows.
How can I get symbol variable here?
def stochastic_updated(self, sender, updated):
self.windows['stochastic'][symbol].Add(updated)

Hi Konstantin,
You can achieve this by creating multiple rolling windows of the same indicators in Initialize method. There you could easily create a list of security symbols and use a loop to access them. Please see my attached backtest for implementation details, and feel free to let me know if you have further questions.
For me it seems like you overwrite same window for every symbol.
How do you access "AAPL" window in your example?
Hi Konstantin,
Sorry that I misunderstood your original question. Here is a community post that you may find helpful. I modified the code Jing Wu provided in this post and am attaching the backtest below. You can see the rolling windows for all symbols printed out in the console. Please check it out and let me know if you have further questions.
