Advanced Trading FAQ
A periodic payment between long and short holders of a perpetual future, which keeps the contract price near spot. When the perpetual trades above spot, longs pay shorts; below, shorts pay longs. It is charged on position size, not margin, so on a leveraged position the cost relative to your own capital is several times what the headline rate suggests.
It is the price at which your margin no longer covers the position's losses. The inputs are entry price, position size, margin posted, and the maintenance margin rate the venue requires. Higher leverage means less margin per unit of position, so the liquidation price sits closer to entry. At 20x it is roughly 5% away, before fees and funding.
Isolated margin caps a position's collateral at what you assigned it — that position can be liquidated without touching the rest of the account. Cross margin lets the whole balance back every position, which delays liquidation but puts everything at risk in one event. Isolated contains damage; cross postpones it.
There is no correct multiple, and any specific number offered without knowing your account is guesswork. The useful framing is inverted: decide what percentage of the account you are willing to lose on the trade, identify where the thesis is wrong, and let those two constraints determine the size. Leverage then falls out of the arithmetic rather than being chosen first.
Perpetual futures with long and short exposure, margin trading on spot pairs, and copy trading for following other traders' positions. DEX+ extends order flow to on-chain markets for tokens not listed centrally. Each carries a different risk profile — futures and margin both introduce liquidation, which spot does not.
