Next question, related to the above - will Binance develop an OCO which will allow trailing on BOTH legs? I.e. in the case of SELL OCO - that the OCO will be the combination of leg-1 being SELL TAKE_PROFIT (stopPrice above market and with trailingDelta as parameter), and leg-2 being SELL STOP_LOSS (stopPrice below market and with trailingDelta as parameter)? I.e. such OCO will have 2 stopPrices and 2 trailingDeltas?
It seems that such OCO could be useful for developing advanced strategies for automated trading.
You can view changelog or follow the gitub repo for SPOT docs to check for any new features with OCOs in the future, but as of this time the OCO for SPOT API is designed with a pair of orders- one algo order order (STOP_LOSS or STOP_LOSS_LIMIT) and a LIMIT_MAKER order.
