A *derivative* is a financial product whose value is derived from an underlying asset. You can read more about it in the Derivatives Trading on Bitfinex article.

**Order Form on the Bitfinex derivatives **

The *order form* is where you put together the order you want to place.

The order form includes:

**Order Type** — The drop-down list, located on the top left of the order form, allows you to select the sort of order you wish to place;

**Price Box** — If placing a Limit/Stop order, here, you can specify the price at which you would like the order to execute/trigger;

**Amount **— Enter the amount you wish to purchase or sell;

**Leverage **— Using the slider, select the amount of leverage you would like for the position. You may also write the number in the leverage box.

**Bitfinex derivatives positions box **

The *positions box* shows all the open positions. When you place an order on the Derivatives platform, you open a position. As you can only have one position per pair, multiple orders on the same pair will contribute to the same position. The amount will become a sum of the orders, and the base price will be a weighted average.

You will find on the positions box:

**Pair **— The derivative pair;

**Amount ** — The size of your position;

**Note: **Positive means it is a long, and negative denotes a short.

**Base Price** — The break-even price;

**Liq Price** — The marked price at which your liquidation will trigger;

**P/L**— The profit and loss shown in the base currency;

**P/L% **— The profit and loss shown as a percentage;

**Collateral **— The amount of collateral assigned to this position.

You can take two actions on the positions box by using the marked buttons displayed in the figure above:

1 — Close the position with a market order

2 — Edit the amount of collateral assigned to the position.

**Summary Box on the Bitfinex derivatives**

The summary box varies according to the pairs chosen and contains a wealth of information about each pair. The following are the descriptions:

**Price Derivative** — The price at which the derivative is trading;

**Price Spot **— The price at which the underlying asset is trading;

**Mark Price **— Average price of the underlying asset based upon the BFX Composite Index (BFXCI), an index of prices obtained from several leading cryptocurrency exchanges in the BTC/USDt and ETH/USDt markets;

**Spread** — The difference in price between the derivative mid-price and the spot price as a percentage;

**Note:** A positive spread indicates that the derivative is trading at a price higher than the market price (at a premium - e.g. 0.25 per cent). A negative spread indicates that the derivative is being traded at a lower price than the market price (at a discount, e.g. -0.25 per cent).

**Liquidation Fund Balance** — the funds currently available in the liquidation fund;

**Funding Rate (current period)** — The funding rate to be applied at the end of the current period;

**Predicted rate** — The predicted funding rate to be applied at the end of the next period;

**Next funding event in** — Countdown to the next funding event;

**Open interest** — Total number of contracts held in an active position.
