POST Reverse Position

Reverses the position specified by instrument in the account.

Combined Close Position and Place Order

POST /v1/api/accounts/{account}/positions/reverseposition

Effectively closes the position and then executes a Place Order instruction if and only if a position already exists. A position must be already open in the specific instrument for this command to work, otherwise an error will be returned and execution will cease. It is otherwise identical to calling Close Position and the Place Order. Returns the Order ID of the newly opened position.
