Invalid Trades with Interactive Brokers Brokerage Model

Hello all. I'm new to QuantConnect and have been working on a simple mean reversion algorithm. It works well, until I add the line:
self.SetBrokerageModel(BrokerageName.InteractiveBrokersBrokerage, AccountType.Cash)
After this, the status of most of my trades become invalid. There is no error message or explanation for it. Does anyone know why this would be happenning? Thank you!

Hi Justin,

Welcome to QuantConnect! Usually an error message is thrown for an invalid order. If you don't see any explanation in the log, you could add this in your algorithm to log every order event:
 

def OnOrderEvent(self, orderEvent):
    self.Log(orderEvent)

With the information you provided, it's hard to narrow down where the problem could be. I'm guessing the reason of invalid orders is `Insufficient buying power to complete order`. For an IB cash account, "Securities settlement generally takes place on the third business day following the sale transaction." More information is here.

Hope it helps.
