Leverage liquidation price calculator API

Compute the liquidation price of a leveraged perp position: long = entry·(1 − 1/L + mmr), short = entry·(1 + 1/L − mmr) where mmr is the maintenance margin rate — plus the price-move buffer to liquidation. Deterministic risk math. Answers 'where do I get liquidated at 10x','liquidation price for a short','how far is my liq price'.
