Share Accumulation — Example
Setup: $1,000/month — 60% Holding A ($250/share), 40% Holding B ($800/share)
Month 1: $600 → A bucket → buy 2 shares ($500), carry $100 | $400 → B bucket, not enough yet
Month 2: $700 for A → buy 2 shares, carry $200 | $800 for B → buy 1 share, carry $0
Unavailable ticker: its budget shifts to the others that month, resumes next month.
