TariffPlan.arbitrage(now=...) drops the points whose period has ended (end <= now), so the cheapest and dearest point can still be traded. decide() (modes off), the modes-on allowed() gate and the Home verdict all pass their own now. Hourly feeds and the static tariff are unchanged. The off-peak sentence and the charge/discharge sentences say "price period". Tests: test_price02.py; test_arbitrage.py rolls its whole-day plans to start at now; test_modes_p3.py part 1 digests leave the trade sentence out (commands unchanged on7a00f12,90bc901and this tree).
