I'm developing a trading bot with Interactive Broker API with python and ib_async library. So far, so good I managed to connect, get data, place order. But I have a question regarding callback function and error. I'm using the following code to place an order def order_filled(trade, fill): """ Called when a order has been placed """ for f in fill: print(f.notvalidname) # it should raise AttributeError here order = ib_api.MarketOrder(BUY, 1) trade = ib.placeOrder(contract, order) trade.fillEvent += order_filled I have voluntarily used a invalid name on the fill object (which is a namedtuple) but still the code is running without catching any errors. I think there is something to do with asyncio but couldn't find any good answer. I will be thankful if someone has a proper explanation. And Is there a way to catch error without using the try/except block ? Many thanks in advance Continue reading...
