# For some backtests with large data python library backtrader runs out of memory and freezes the system
# Since I use Ubuntu I can prevent this by increasing available SWAP memory

# Add more SWAP memory
sudo fallocate -l 10g /mnt/additional.swap # Create a file with a fixed size
sudo chmod 600 /mnt/additional.swap # Set needed permissions in order to use as SWAP file
sudo mkswap /mnt/additional.swap # Format as swap file
sudo swapon /mnt/additional.swap # Use NOW as SWAP temporarily
echo '/mnt/additional.swap swap swap defaults 0 0' | sudo tee -a /etc/fstab # Use permanently as SWAP
