Distance to liquidation is the real buffer
Entry price alone does not tell you risk. Liquidation calculators estimate where a venue may force-close based on leverage, margin mode, and maintenance assumptions.
Mark price and insurance funds differ by exchange — treat CryptonicTools output as planning math, then confirm on your venue.
Pair liquidation with position size
Position size and risk/reward tools help you decide how much to risk for a given stop. Liquidation math then checks whether leverage puts the forced exit inside that stop.
If liquidation sits closer than your planned invalidation, the position is over-levered for your rules.
Practical checklist
Write max loss first. Size the position. Check liquidation distance. Only then look at mid-market converters for fiat context.
