Levels are estimated, not observed. Each candle is assumed to open positions at its price, and levels are derived from P_liq = P_entry × (1 ∓ 1/L ± MMR). The model has three terms:
Size = open-interest increase (not volume — volume also counts closes and the same money changing hands; an OI increase is a newly opened position). Side = long/short account ratio (not a flat 50/50). Leverage = ASSUMED (a 5x…100x ladder skewed to the low end; entry price is spread across the candle range) — leverage is notional ÷ margin, and margin is private per account, so it cannot be read from OI or funding. Funding is shown for context only; the side is already carried by the long/short ratio, so it is not counted twice. A level accumulates until price reaches it, and burns the moment it is touched. Bright bands mean “if price goes there, dense liquidations have piled up” — not “liquidations happened there”.
