*There is a minimum provide (maker) size of 0.01 on BTC-PERP. This is further explained in Complete Futures Specs.
Accounts
Position notional: position size * MP
IMF Factor: multiplier on the margin required for a coin.
Base IMF: the minimum initial margin fraction needed. This is 1 / maximum leverage.
Position initial margin fraction: max(Base IMF, IMF factor * sqrt(position open size))
Position maintenance margin fraction: max([3% if you're using 20x maximum leverage or less, 0.60% if you're using 50x maximum leverage or more], 0.6 * position initial margin fraction)
Position unrealized PNL: size * (future mark price - position entry price)
Collateral: USD balance in futures wallet plus 0.95 times BTC and USDT balance marked to latest index price.
Free collateral: amount of USD that can be withdrawn from exchange, =min(collateral, collateral + unrealized PNL) - [amount of collateral tied up in open orders]
Total account value: collateral + unrealized pnl
Total position notional: sum of abs(position notional) across all positions
Margin fraction [MF]: total account value / total position notional
Maintenance Margin Fraction Requirement [MMF]: the minimum MF needed to avoid getting liquidated, equal to average of position MMF weighed by position notional
Auto Close Margin Fraction [ACMF]: the minimum MF needed to avoid getting closed against the backstop liquidity provider or other users, = max(MMF / 2, MMF - 0.06 * MM)
Zero Price (ZP): MP * (1 - MF) if long, MP * (1 + MF) if short. The mark price that would set an account’s total account value to 0.
Liquidation Distance: % move in futures that would make MF = MMF.
Position open size: Max(abs(size if all buy orders get filled), abs(size if all sell orders get filled))
Position open notional: position open size * MP
Total open position notional: sum of abs(position open notional) across all positions
Open margin fraction [OMF]: min(total account value, collateral) / total open position notional
Initial Margin Fraction Requirement [IMF]: the minimum OMF needed to increase position size, equal to average of position IMF for all account positions weighed by position open notional
Unused collateral: max(OMF - IMF, 0) * total open position notional
Backstop Liquidity Provider [BLP]: an account that promises to take on liquidating accounts’ positions
