Day-by-day tiered profit-target exit, computed in-browser on demand from real OHLC data (since 02 Jan 2015). Minimum hold is a floor — no exit fires before it elapses, regardless of profit. Tiers are evenly spaced % gains off each position's own entry price. Tier count alone determines the sell size: each tier sells the same fixed block, measured in UNITS (shares) — 100 / tier count, sized off the ORIGINAL unit count, e.g. 4 tiers = four 25%-of-original-units blocks. Because the open position keeps shrinking in unit terms while each block stays the same size, this is equivalent to selling a growing share of whatever units are still open (1/4, then 1/3 of what's left, then 1/2, then all of it) — the final tier always closes whatever remains. This is a unit-count split, not a dollar-value split: since price is higher at later tiers, the same fixed unit block realizes more dollar profit each time, even though the % of units sold is identical. Standard mode enters sector-ETF M Signals only — SPY/QQQ/DIA/IWM signals are ignored entirely, never opened as positions. Broad-market early exit mode force-liquidates every open position immediately on a SPY/QQQ/DIA/IWM M Signal, regardless of tier progress — this is layered on top of the tiered mechanic, not a replacement for it. No distinction mode adds QQQ/DIA/IWM as tradeable positions alongside the sector ETFs, with no other change to entry or exit rules.
