# 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.\
\
***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?

Orders are executed in accordance with the factual [Order book](/help-center/crypto-futures-platform/workspace.md#order-book) prices. Unlike in the old trading platform where orders are executed by [Bid/Ask](/help-center/trading-with-primexbt/order-types.md#bid-price-ask-price-and-spread) quotes received from liquidity provider.

### Is margin reserved for Stop orders?

No, margin is not reserved for [Stop](/help-center/trading-with-primexbt/order-types.md#stop-order) orders as they are not placed in the Order book towards market making.

### Is margin reserved for Limit orders?

Yes, margin is reserved when placing [Limit](/help-center/trading-with-primexbt/order-types.md#limit-order) orders, i.e. towards market making.\
\
For example: If a Limit order size 1 BTC with the BTC/USD instrument is placed in the Order book, a margin reserve of 0.0005 BTC will be applied, regardless if the Limit order was executed or not.

### Is there a difference between market maker / taker fees?

Yes, market maker and market taker fees may differ.\
\

\
**Taker fee** — a fee that a trader pays when he places a stop or market order that was executed on the market, including instantly executed limit orders.

\

The [Contract Specification](/help-center/crypto-futures-platform/workspace.md#contract-specification) section of your [workspace](/help-center/crypto-futures-platform/workspace.md) reflects the current financing rate due.
