New Order List - OTOCO (TRADE) — Place an `OTOCO`. - An `OTOCO` (One-Triggers-One-Cancels-the-Other) is an order list comprised of 3 orders. - The first order is called the working order and must be `LIMIT` or `LIMIT_MAKER`. Initially, only the working order goes on the order book. - The behavior of the working order is the same as the `OTO`. - `OTOCO` has 2 pending orders (pending above and pending below), forming an `OCO` pair. The pending orders are only placed on the order book when the working order gets fully filled. - The rules of the pending above and pending below follow the same rule
