Source: https://www.nordnet.dk/externalapi/docs/api

Allows users to place various types of orders for financial instruments, including normal, limit, stop-loss, and OCO orders. It supports specifying details like volume, price, activation conditions, and validity periods.

```APIDOC
## POST /api/2/orders

### Description
Places an order for a financial instrument. Supports various order types and configurations.

### Method
POST

### Endpoint
/api/2/orders

### Parameters
#### Header Parameters
- **Accept-Language** (enum: da, de, en, fi, nb, nn, no, sv) - Optional - Language preferred in the response. Overrides the session language. Note that `nb` and `nn` are equivalent to `no`.
- **Authorization** (string) - Optional - Basic authorization header, that is the value must be `Basic <credentials>` where `<credentials>` is the base64 encoded string `<session_id>:<session_id>`.

#### FormData Parameters
- **accid** (integer(int64)) - Required - The account identifier for the account. Some systems can or must use the account number as account identifier.
- **activation_condition** (string) - Optional - Used for stop-loss orders. `STOP_ACTPRICE_PERC` - Trailing stop-loss. The order is activated when the price changes by the given percentage. The fields `target_value`, `trigger_value` and `trigger_condition` are required and the `price` field should be omitted. `STOP_ACTPRICE` - The order is activated when the market price of the instrument reaches a trigger price. The fields `trigger_value`, `trigger_condition` and `price` are required. `MANUAL` - The order is inactive in the Nordnet system until it is manually activated by the customer. `OCO_STOP_ACTPRICE` - One cancels other orders. Our implementation is one normal order and one stop-loss order. If the real order is executed the stop-loss is cancelled. If the stop-loss triggers the normal order is canceled. This combination is always displayed as one order.
- **currency** (string) - Optional - The currency that the instrument is traded in.
- **extended_hours** (boolean) - Optional - If `true`, order is applicable for US pre-market trading. Defaults to `false`.
- **identifier** (string) - Optional - Nordnet tradable identifier.
- **market_id** (integer(int64)) - Required - Nordnet market identifier.
- **open_volume** (integer(int64)) - Optional - The visible part of an iceberg order. If this field is omitted the whole volume of the order is visible on the market. This field is only allowed if the order type is `LIMIT` or `NORMAL`.
- **order_type** (enum: FAK, FOK, NORMAL, LIMIT, STOP_LIMIT, STOP_TRAILING, OCO) - Optional - The order type. Defaults to `NORMAL`. When using `NORMAL` the system guesses the order type based on used parameters. For better parameter validation and to ensure that the order type is the desired one the client should not use `NORMAL`, but rather the intended order type instead. `NORMAL` will be deprecated in future versions.
- **price** (number(double)) - Optional - The price limit of the order.
- **reference** (string) - Optional - Free text reference for the order. Intended for the customer.
- **side** (enum: BUY, SELL) - Required - `BUY` or `SELL`.
- **target_value** (number(double)) - Optional - Only used when `type` is `STOP_ACTPRICE_PERC` or `OCO_STOP_ACTPRICE`. This is the price on the market. If `type` is `STOP_ACTPRICE_PERC` the value is given in percentage points. The price will be `trailing_value + (target_value percentage of trailing_value)`. If `type` is `OCO_STOP_ACTPRICE` the price is a fixed price.
- **trigger_condition** (string) - Optional - The comparison that should be used on `trigger_value`. Valid values are `<=` (less than or equal to) or `>=` (greater than or equal to).
- **trigger_value** (number(double)) - Optional - If `type` is `STOP_ACTPRICE_PERC` the value is given in percentage points. Minimum value is `1` for `STOP_ACTPRICE_PERC`. If `type` is `STOP_ACTPRICE` the value is a fixed price.
- **valid_until** (string(date)) - Optional - Date formatted as `YYYY-MM-DD`. If this field is left out the order is a day order - that is, the same behavior as if `valid_until` is set to today. Smart-orders can only be day orders.
- **volume** (integer(int64)) - Required - The volume of the order.
