execute against 2 (or more) different data sets
-
I've loaded up 2 data files (2 different symbols).
I want to run the same strategy on them both, but when i execute, only the first one actually gets executed, though they both get plotted. Not quite sure how to do this, or if i need to run them separately? I have 2 datafeeds, 1 strategy. I can run them separately, but it's faster if I can run them together and get the final $ result together.

Sorry, but it really seems unclear what you want and without any code it seems the platform is doing what is requested to do.
- You add 2 data feeds to the system
- You get 2 data feeds in the strategy
- You get 2 data feeds plotted
So far so good.

okay, i see they get added as new data feeds, which makes sense. not what i wanted, but i'll just execute twice, no problem.
-
yes, all working. what i wanted was just to add 2 symbols and have the strategy execute against both of them (independently) - but I see how it's more flexible and powerful this way.

The summary: you are trying to reuse a
Cerebrofor the execution of the sameStrategyon different data sets.You need 2 execution runs and in each you add the appropriate data feed to the system. After
runa cerebro instance holds all the strategies, datas, analyzers and indicators after they have come to the last point. The instance is not meant to run again with a different data feed.Create another cerebro instance (given it is the same strategy, a loop make sense)
