On the left-hand side of BTSE's trading interface, below your order details, you will find the Margin Mode / Leverage button. This is where you can adjust how much leverage you want to use for each order.
To change the amount of margin or leverage for an order, click on Margin Mode / Leverage. Clicking on this section shows the term “Cross,” as well as leverage from 1x to 100x.
On the BTSE exchange, you have a cross wallet. If you deposit funds into this wallet, you are able to draw from those funds for multiple positions and trading products.
For example, if you have $10,000 in your cross wallet, you can trade any product on the BTSE exchange using those funds, as long as you choose the cross margin setting. You can use those funds to support a Bitcoin Perpetual Futures Contract (BPFC) position, while also using them to support an Ethereum Perpetual Futures Contract (EPFC) at the same time, provided you have enough funds in your cross wallet for the trades you are looking to enter. The cross wallet setting also holds 1x margin, so if you use $8,000 on a BPFC position, you have $2,000 left for another position, such as an EPFC position.
Additionally, if you simultaneously hold an open BPFC position that is in the green and an open EPFC that is in the red, the unrealized gains from the winning BPFC position compensate for the losing EPFC position, in tandem with your cross wallet, unless losses become too high.
Clicking on 1x margin allows you to trade based solely on the funds currently in your wallet for the product you are trading. For example, if you have $1,000 in your BPFC wallet, you can only open a $1,000 position.
If 1 Bitcoin (BTC) is trading at $10,000, 1x margin only allows you to enter a 100 BPFC position (0.1 BTC) if you have $1,000 in your BPFC wallet. If you use 10x margin under the same circumstances, however, you can open a 1,000 BPFC position (1 BTC).
