Dear all,

My issue is the following: "BrokerageModel declared unable to submit order" for StopLimit sell orders on GDAX. I attached the backtest to this post.

I see two possibilities for that:

1) The BrokerageModel implemented by QC does not follow GDAX order model, as I know that there is the possibility to place stop limit orders using GDAX user interface. Furthermore, I think that GDAX API also allows stop limit orders: .https://docs.gdax.com/#place-a-new-order.

2) There is some kind of mishandling of the stop limit order from my side.

If 1), how can I simulate a stop limit order using: stop orders, limit orders, order event monitoring and price data monitoring?

Thank you. Cordially, Benjamin.
