logigrain.net/api/nisa

Japan new NISA limits: how much can still be bought this year and next year under the annual limits (つみたて 1.2M / 成長 2.4M yen) and the 18M-yen lifetime book-value limit (成長 up to 12M). Selling frees the book value (cost), not the sale price, from the next year. Returns the rule basis, assumptions, what would change the answer and a quotable sentence; asks for book values instead of guessing. Rules checked against the FSA NISA site.
