Bracket order with trailing take-profit/stop-loss

[Mike1]

how to modify for example below code to get trailing stop loss / take profit price? The docs after weeks of exploring is awfully insufficient to answer something so basic

# Bracket order with limit order as initial order
limit_bracket_order = client.submit_order(LimitOrderRequest(
          symbol='SPY',
          qty=1,
          side=OrderSide.BUY,
          limit_price=350.00,
          time_in_force=TimeInForce.DAY,
          order_class = OrderClass.BRACKET,
          stop_loss=StopLossRequest(stop_price=300.00),
          take_profit=TakeProfitRequest(limit_price=500.00)
          ))
