Hi all,

In vectorbt how can we implement the following bracket order?

For a long trade on a stock that is currently trading at 110 USD, send three orders:

Parent order: A limit buy order @ 100 USD, with a limited time in force
A trailing stop loss order with a stop amount of 5 USD, i.e. once the parent buy order is executed at 100 USD, the trailing stop will be initiated at 95 USD and the trailing stop price will increase whenever the stock price increases, but trailing stop price never decrease
A trailing take profit order where the take profit price is linked to the trailing stop price plus some add-on, i.e. trailing take profit price is always equal to the trailing stop price plus 15 USD.
Trailing stop and trailing take profit orders will be activated only if the parent order is executed.
Trailing stop and trailing take profit orders will be canceled if the parent order is cancelled.
Trailing stop loss and trailing take profit orders form a one-cancels-others (OCO) set. If one of them is executed the other will be canceled.

Thanks
