IBKR live place an order

[mmbot]

Hi!

Like to humbly ask for help.

I tried to place an order to TWS with this code.

            if self.action == 'long':
                print('price decide on: {:.5f} '.format(self.data0.close[0]), self.data0.datetime.datetime(0))
                self.ATR_at_exe = self.atr[0]
                self.long_parent_order = self.buy(exectype=bt.Order.Market, size=exe_size, transmit=False, valid=60)
                self.long_stoploss = self.sell(price=sl_px, exectype=bt.Order.Stop, transmit=True, parent=self.long_parent_order)
                self.long_parent_order.addinfo(name='Parent Long Bracket Main-cond 1xATR, Target 1ATR {:.5f}, SL: {:.5f}'.format(self.data0.close[0] + self.ATR_at_exe, sl_px))
                self.long_stoploss.addinfo(name='Parent Long Bracket Stoploss-cond 1.5xATR, sl_px {:.5f}'.format(sl_px))

                self.action = 'nothing'

But I am getting this error:

Any help much appreciated!
