# Take profit and stop loss (TP/SL)

AFX provides flexible Take Profit (TP) and Stop Loss (SL) options that can be set when placing an order or added to an existing position.

## Setting TP/SL on Orders

When placing a Market or Limit order, you can attach TP and SL triggers. The default mode is **Entire Position** — the TP/SL applies to your full position for that symbol. The trigger price type defaults to **Last Price**.

TP/SL can be defined using four methods:

### 1. Trigger Price

Set a specific price at which the TP or SL should trigger. The system displays which direction (Long/Short) the TP/SL applies to and the estimated PNL.

### 2. Price Change (%)

Define the TP/SL as a percentage change from the estimated entry price.

* Long TP: Trigger Price = Entry Price × (1 + change%)
* Long SL: Trigger Price = Entry Price × (1 - change%)
* Short TP: Trigger Price = Entry Price × (1 - change%)
* Short SL: Trigger Price = Entry Price × (1 + change%)

### 3. ROI (%)

Define the TP/SL based on the return on investment, which factors in leverage.

* Long TP: Trigger Price = Entry Price × (1 + ROI% / Leverage)
* Long SL: Trigger Price = Entry Price × (1 - ROI% / Leverage)
* Short TP: Trigger Price = Entry Price × (1 - ROI% / Leverage)
* Short SL: Trigger Price = Entry Price × (1 + ROI% / Leverage)

### 4. PNL (USDC)

Set the TP/SL based on a specific profit or loss amount in USDC.

* Long: Trigger Price = PNL / Order Size + Entry Price
* Short: Trigger Price = Entry Price - PNL / Order Size

## Setting TP/SL on Positions

You can add or modify TP/SL on an existing position from the position panel. When setting TP/SL on a position:

* You can choose **Entire Position** mode or specify a custom size (**Partial** mode).
* Trigger price type supports both **Last Price** and **Mark Price**.
* The system displays estimated PNL based on the trigger price and current position parameters.

## TP/SL Behavior in One-Way Mode

In One-Way mode, TP/SL interactions follow specific rules when new orders are placed:

* **Adding to a position (same direction):** Existing TP/SL is preserved. If the new order also has TP/SL, the new settings override the existing ones.
* **Closing/reversing a position (opposite direction):** If the existing position has TP/SL, those TP/SL orders are automatically cancelled when the position is closed.
* **Partial close:** Existing TP/SL remains active and applies to the remaining position.

## Execution

When a TP/SL is triggered, it submits a **Market Order** to close the position (or the configured portion). Standard slippage protection applies.
