# FAQ: Essential trading features ### What is position netting? When executing additional positions with the same instrument, they are added or reduced to/from the initial position opened regardless of their direction - *Buy* or *Sell*. This is called **position** **Netting.**\ \ For example, if a *Sell* position of 0.5 BTC with BTC/USD instrument is opened, and an additional *Sell* position of 0.5 BTC is executed, it will be added to the initial position resulting in a total of 1 BTC *Sell* position.\ \ And vice-versa. if a *Buy* position of 0.5 BTC with BTC/USD instrument is opened, and an additional *Sell* position of 0.2 is executed, it will reduce the initial position resulting in a total of 0.3 BTC *Buy* position. ### What will be the open price of my net positions? *Open Price* of **net positions** is a **weighted average** open price of all positions combined.\ \ For example: If a *Buy* position for 1 BTC with the BTC/USD instrument is opened at the price of $20,000, and an additional *Buy* position for 1 BTC is executed with the same instrument (BTC/USD) at the price of $30,000 – the **net position** will be a total of 2 BTC at the **weighted average** *open price* of $25,000. ### What is the difference between Cross and Isolated Margin? ***Cross margin*** is a type of margin that is shared between all open positions. When choosing this type of margin, *Leverage* is **applied automatically** in accordance with your order size and cannot be set manually.\ \ \&#xNAN;***Isolated margin*** is a type of margin that is segregated for a specific order or position. When choosing this type of margin, you can **adjust** **and select** *Leverage* that will be applied to your order.\ \ When **adjusting Margin type** or **Leverage** for the selected instrument in the Place Order section, the trading conditions change and **apply to the whole net position** after placing the order. ### How are my orders executed?

Yes, market maker and market taker fees may differ.\ \ **Maker fee** — a fee that a trader pays (or a rebate that he will receive) when he places a limit order that was executed on the market.
