Error message received: 

Order Error: id: 1, Insufficient buying power to complete order (Value:XXX), Reason: The 'AAPL' security is not supported by this cash model. Currently only SecurityType.Crypto and SecurityType.Forex are supported.

I have not previously seen this.  I am using the Default brokerage model and have also tried with the QuantConnect Brokerage.  Is there a system issue being worked through?  Or a fix identified?

 

Thank you
