High Leverage

Notes:

1. FTX is not offered to US users.
2. Cryptocurrencies can be volatile; using high leverage on them increases the volatility and thus the risk.  Only use high leverage if you understand and are able to accept this risk, including both market risk and liquidation risk.
3. Index and futures prices can diverge, and it's not always clear which price markets will stabilize at.  FTX's risk engine is based on futures market prices, not index prices, and so liquidations can be triggered by moves in futures contracts.

FTX supports 50x, 100x, and 101x Leverage!

Users can select these options from the Settings page. Users must have no open positions and no open orders in order to select these options.

We advise that users only select these options after careful consideration of their increased risk of liquidation.

To mitigate this risk, both for users and for FTX, users that select a leverage option greater than or equal to 50x are subject to:

• Position limits
• 0.02% additional maker and taker fees for 50x
• 0.03% additional maker and taker fees for 100x and 101x

Position limits

Users are limited to $2.5m in weighted position size, across all subaccounts with high leverage, including consideration of open orders. FTX will prevent users from placing orders that would let them exceed this limit, and will prevent users that exceed the limit from switching to a high leverage option.

Your used and total position limit can be seen on trade pages:

Weighted position size is equal to the sum of ((position and open order size) * (future mark price) * (future position limit weight)) over all markets.

Future position limit weights vary by underlying. 

Note that the effective position limit weight is two times higher for non-perpetual futures.

Maintenance Margin

Maintenance margin is set to 0.60% for accounts with 50x and higher leverage.  The auto-close margin fraction is 0.30%.

Fees

Accounts using 50x leverage will be charged an additional 0.02% in maker and taker fees; accounts using 100x or 101x will be charged an additional 0.03%. The additional fees charged will go towards the insurance fund to address the account's higher risk of liquidation.

Because of this, you can't change to 50x or higher leverage while you already have a position open; doing so would circumvent the insurance fund additions.  You can either close positions and then switch to 50x +, or you can do it in a new subaccount.
