On September 27th 2018, we made the following updates to our trading engine. These changes may affect the way you do margin* trading.
Funds used in spot positions on margin are now withheld.
- This will prevent traders from converting their margin collateral into a non-collateral currency (which could cause a liquidation).
- This will also prevent margin collateral from being converted into other collateral currencies.
- Collateral withheld per position is approximately the cost of the position divided by the leverage used, and then adjusted by the current profit/loss of the position.
Calculations for available margin have been updated.
- Profit/loss and open orders are now taken into account when placing a new order.
- Margin orders can no longer be placed using margin that is also being used in a different margin order. Previously, these orders would fail upon being triggered. Now the orders fail at creation.
- Buy-side and sell-side margin withholdings are not withheld in the opposite direction, up to the point of the original order. For example, if you have a 5 BTCUSD sell order that maxes out your margin, you can still place a 5 BTCUSD buy order (but not a 6 BTCUSD buy).
