I have recently used Backtrader. During optimization, the package works properly when the input data is low. But when the input data is high or the number of modes I want to multi-core optimization, I get the following error:

Out of memory error when running optstrategy

After checking, I realized that because the results are stored in a list, in this case, despite the 32 GB of RAM, this list is full and the package gives an error.

How can I solve this problem?
