I'm running an algorithm where I'm trying to call the past 64 days of historical data for each symbol in a list of symbols through a ‘for’ loop when rebalancing monthly. However, I keep encountering this error even though I have set a warmup of 360 days through my Initialize method. Any ideas why?
ValueError : Wrong number of items passed 64, placement implies 1

Hi Nested Technologies
Can you attach some of your code on that iteration part of the for loop? It is impossible to debug in this little information.
Thanks
Louis

It's OK! I managed to solve it. Just had to put my WarmUp call before my History call. Thanks!
