OCO orders

When I use a OCO order I want to tell binance that when the last price traded of ADA is say $0.5, to sell my entire holding of this asset using the OCO request below.

What will my request look like when I send it to binance?

I suggest having a look at stop orders instead of oco orders.

OCO orders have two stop legs, a TAKE_PROFIT and a STOP_LOSS. If either of the order activates, the other order is canceled.
