# TP/SL, Triggers, and Reduce-Only

### Overview

* **TP/SL**: Attach Take Profit and/or Stop Loss settings to an entry order using the `tpsl` object.
* **Modes**:
  * **Full**: Configures TP/SL in full mode.
  * **Partial**: Configures TP/SL in partial mode.
* **TP/SL order types**: `take_profit` and `stop_loss` support `market` or `limit` configurations.
* **Trigger**: Conditional orders use a `trigger` object with:
  * `trigger_by`: `"LastPrice"`, `"IndexPrice"`, or `"MarkPrice"`.
  * `trigger_direction`: `"Up"` or `"Down"`.
  * `trigger_price`: The price level that activates the order.
* **Reduce-only**: Use `reduce_only: true` to prevent an order from increasing position exposure.

}
```

### Behavior details

* **Conditional orders**
  * The `trigger` object defines the price source (`trigger_by`), trigger direction (`trigger_direction`), and activation price (`trigger_price`).
* **Full mode**
  * Configured using `tpsl.mode: "Full"`.
  * Take Profit and Stop Loss settings are defined through `take_profit` and `stop_loss`.
* **Partial mode**
  * Configured using `tpsl.mode: "Partial"`.
  * Take Profit and Stop Loss settings are defined through `take_profit` and `stop_loss`.
* **TP/SL triggers**
  * Take Profit and Stop Loss configurations specify their trigger settings within the selected `market` or `limit` configuration.
* **Reduce-only**
  * Use `reduce_only: true` to prevent an order from increasing position exposure.

{/* TODO(BACKEND): Confirm whether `SLIPPAGE_GUARD_BPS` is still used in the current Canton backend and whether the default value remains 200 bps (2%). */}

{/* TODO: Replace legacy TP/SL WebSocket examples with current Canton private stream events for `order`, `execution`, and `position` after capturing an actual TP/SL trigger and execution flow. */}
