Enter your balance, leverage and entry price to see the biggest position your margin allows.
Your margin limits the size of a leveraged position. The most you can open is your available balance multiplied by the leverage. With 1,000 USDT of margin at 20x, that is 20,000 USDT of position value. Dividing by the entry price turns the value into a quantity of coins, so at 60,000 USDT per coin the most you could open is about 0.3333 coins.
An exchange takes the opening fee from your balance, so the margin you can use for the position is a little smaller than the whole balance. Enter the fee as a percentage of the position value, and the calculator solves for the largest position where the margin plus the fee equals your balance. Leave it at 0 for the simple result.
Real exchanges also cap the position by leverage tier, so a high leverage may not be allowed for a large position. Open orders and other positions can use some of your margin too. Check the maximum shown in your trading app before placing an order, and remember that the biggest possible position is rarely the wisest one, since it sits very close to its liquidation price.
Multiply your available balance by the leverage to get the position value, then divide by the entry price to get the quantity.
The size is the same either way. The side only affects where the position would be liquidated.
Usually not. A position that uses all your margin sits very close to liquidation, so a small move against you can wipe out the margin.
The opening fee is paid from the same balance as the margin, so a little less is left for margin.
No. Exchanges may restrict the leverage for large positions, so the real maximum can be lower.
