Hello everyone, im developing  boilinger band strategy using eth-usd and GDAX coin base pro brokerage. 

My backtests are running perfect, the problem is when I put it live when it tries to buy or sell this message is shown.

BrokerageModel declared unable to submit order

Im not sure if I should make a change to the types of orders but I actually don't know. Hope anyone of you guys could help me 

 

Thanks
