2/9 Quick overview: leverage trading is a double-edged sword. It allows traders to amplify their exposure to an asset with borrowed funds, increasing potential P&L. Liquidation occurs when a trader's losses deplete his collateral, triggering an automatic closure of their position

6/9 On GMX, your collateral after P&L needs to be at least 1% notional or $5. This constraint needs to hold to not get liquidated, so we need to solve for the lower bound of exit price (p_j). It comes out to this, check out the medium post for full steps.
