Ouinex 4.35 added a direct route to your API keys and a permission model that lets you decide exactly what each key can do. The two changes go together: a key is much safer to create when you can restrict it to the one thing you need it for.
Until 4.35, changing the leverage on an order meant cancelling it and placing it again. From this release you can change it in place, on an open position, and on a pending limit order, without touching the order itself.
Slippage Control is a vital tool that allows you to set a maximum price boundary for your trades, ensuring you never pay more, or receive less, than you intended during volatile market conditions.
