#### ¹**Setting Market Leverage**
The market leverage set changes your tabulated “cost”, which represents the portion of your available funds used as margin for a specific position. Adjusting the market leverage consequently alters the liquidation price associated with that position.
Let's consider a scenario where you hold a long futures position. Increasing the leverage reduces your "cost" or margin funds, minimizing the amount you would lose if liquidated. However, it also significantly raises the liquidation price, meaning that even a slight drop in the mark price could result in liquidation.
As the "cost" for the position decreases, you can take on a larger position using the same margin, potentially yielding higher gains.
It is easier to think about leverage by deciding on the quantity of Bitcoin you want to buy in futures, as this determines how much you will profit given a change in the mark price. This quantity of Bitcoin in futures is now the position you intend to open, and you can then select the desired leverage based on your risk tolerance.
