⚠️ LMEX futures fees: Maker 0.02%, Taker 0.06%. Spot: Maker 0.1%, Taker 0.1%. Using maker (limit) orders saves significant costs over time.
💡 On a $10,000 position with 10× leverage, a 0.1% fee difference between maker and taker saves $10 per trade. Over 100 trades that's $1,000.
Liquidation Price Calculator
Know exactly where you get liquidated before you open a position. Essential for every leveraged trade on LMEX.

⛔ Always set a stop loss before the liquidation price. A 1% move on 100× leverage wipes your entire margin. Use ISOLATED margin on LMEX to protect other positions.
