notify_trade not firing on subsequent trades when using tradeid?


  • Hi all,

    I've been experimenting with multiple parallel trades using tradeid and it seems that the strategy.notify_trade method is not firing for cases when there's a new order added to an existing trade?

    I'm using a sample strategy that simply buys and sells in waves of 10 buy/sell orders, which are distributed to 5 different trades, so at the end every trade consist of a BUY(1) BUY(2) SELL(1) SELL(2) sequence of orders. The sizer is the FixedSizer(stake=0.01).

    I have two issues:

    1. I'm not getting the notify_trade to fire during the BUY(2) and SELL(1) orders, it's only fired during the opening BUY(1) and closing SELL(2) orders
    2. after a while, the notify_trade does not even fire for the opening BUY(1) trade (see below at 2017-08-18T03:00:00 in the log)

    The strategy:

    import backtrader as bt

class SampleStrategy(bt.Strategy):
	def log(self, txt, dt=None):
		''' Logging function for this strategy'''
		dt = dt or self.datas[0].datetime.datetime(0)
		print('%s, %s' % (dt.isoformat(), txt))

	def __init__(self):
		self.livetrades = {}
		self.counter = 0

	def notify_order(self, order):
		if order.status in [order.Submitted, order.Accepted, order.Partial]:
			# Buy/Sell order submitted/accepted to/by broker/partially filled - Nothing to do
			return

		# Check if an order has been completed
		if order.status in [order.Completed]:
			if order.isbuy():
				self.log('BUY EXECUTED, Price: %.2f, Cost: %.2f, Comm %.2f, tradeID: %d' %(order.executed.price, order.executed.value, order.executed.comm, order.tradeid))
			elif order.issell():
				self.log('SELL EXECUTED, Price: %.2f, Cost: %.2f, Comm %.2f, tradeID: %d' %(order.executed.price, order.executed.value, order.executed.comm, order.tradeid))

		elif order.status in [order.Canceled, order.Margin, order.Rejected]:
			self.log('Order Canceled/Margin/Rejected')

	def notify_trade(self, trade):
		if trade.justopened:
			self.log('New trade just opened with id %d'%(trade.tradeid))
			self.livetrades[trade.tradeid] = trade
		elif trade.isclosed:
			self.log('A trade just closed with id %d'%(trade.tradeid))
			self.livetrades.pop(trade.tradeid)
		else:
			self.log('Trade id %d updated'%(trade.tradeid))

	def next(self):
		self.log('______Starting NEXT()______')

		if 0 <= self.counter % 20 < 10:
			self.buy(tradeid=self.counter%5)
		else:
			self.sell(tradeid=self.counter%5)
		self.counter += 1

		self.log('Currently %d trades open with ids=%s'%(len(self.livetrades), ','.join([str(k) for k in self.livetrades.keys()])))

    Here's the log:

    Trades are only notified when opened and closed. All intermediate states are not notified (the trade is updated though)

  • @backtrader OK, it seemed like that but I wasn't sure. Now the remaining question is why didn't the notify_trade fire for the opening BUY(1) at 2017-08-18T03:00:00, I'll try to look into it more
    Thanks
