How can I add the name of the data feed to the print log for a buy or sell?

Picture Perfect

Hi all -

Does anyone know how to add the name of the data feed to the log for a buy or sell? I looked through the order object documentation, but didn't see something part of order.executed that makes sense to add.

if order.status in [order.Completed]:
		if order.isbuy():
			self.portfolio_value = self.broker.get_value()	
			self.percent_of_portfolio = order.executed.value / self.portfolio_value		   
			#'''
			self.log(
				'BUY EXECUTED, Price: %.2f, Cost: %.2f, Comm %.2f, Size %.2f, port_value %.2f percent_of_portfolio %.2f' %
				(order.executed.price,
				 order.executed.value,
				 order.executed.comm,
				 order.executed.size,
				 self.portfolio_value,
				 self.percent_of_portfolio))
			#'''
			self.buyprice = order.executed.price
			self.buycomm = order.executed.comm

		else:  # Sell
			#'''
			self.log('SELL EXECUTED, Price: %.2f, Cost: %.2f, Comm %.2f, Size %.2f, Value %.2f' %
					 (order.executed.price,
					  order.executed.value,
					  order.executed.comm,
					  order.executed.size,
					  order.executed.price * order.executed.size))

order.executed contains the data on which the action took place.

Try data._name if you have named it when adding it to cerebro vía adddata(xxx, name='yyyy')

If the dataname parameter in your data feed is something meaningful like a ticker name, try: data.p.dataname (the dataname parameter can be anything, for example a handle to a database)

if you set data name in add data,you can use:

self.log("buy result: data:{},buy_price:{},buy_cost:{},commission:{}".format(order.p.data._name,
                            order.executed.price,order.executed.value,order.executed.comm))

order.p.data._name
