Crypto paper-trading

Hi there,
Sorry if this question seems so straightforward, but i've not been able to figure it out!

I'm trying to papertrade with GDAX using the "live-paper" environment but am not having any success. I've tried to setting data-queue-handler to GDAXDataQueueHandler, but am probably missing something obvious. GDAX doesn't have a demo account for testing trades, but is this possible with LEAN?

I have no problems with GDAX and live trading, but wish to run my algorithm on paper before I set it free :)

Thanks so much in advance

You have to merge the "live-paper" and "live-gdax" configuration settings to make a new one "paper-gdax".

Changed: 

 - to PaperBrokerage class
 - to BacktestingTransactionHandler

"paper-gdax": {
"live-mode": true,

// real brokerage implementations require the BrokerageTransactionHandler
"live-mode-brokerage": "PaperBrokerage",

"data-queue-handler": "GDAXDataQueueHandler",
"setup-handler": "QuantConnect.Lean.Engine.Setup.BrokerageSetupHandler",
"result-handler": "QuantConnect.Lean.Engine.Results.LiveTradingResultHandler",
"data-feed-handler": "QuantConnect.Lean.Engine.DataFeeds.LiveTradingDataFeed",
"real-time-handler": "QuantConnect.Lean.Engine.RealTime.LiveTradingRealTimeHandler",
"transaction-handler": "QuantConnect.Lean.Engine.TransactionHandlers.BacktestingTransactionHandler",
"history-provider": "BrokerageHistoryProvider"
}

Thanks for your reply. I have tried with your configuration settings, but get thrown the following error:

 

ERROR:: Algorithm.Initialize() Error: Cannot create an instance of type 'QuantConnect.Brokerages.GDAX.GDAXDataQueueHandler' because a constructor could not be selected for construction. Ensure that the type either has a default constructor, or a single constructor marked with the 'System.ComponentModel.Composition.ImportingConstructorAttribute'.
