Would like to trade between USD and BTC on coinbasepro based on MACD signal line crossing.

The trigger on MACD is easy enough to configure.

The Message part I am having trouble with.

Want to test with 1 BTC back and forth. The Message I have figured out so far is:

# believe this would sell 1btc to USD, but it does not seem to be working:
e=gdax s=BTCUSD b=sell q=1 t=market u=currency

The trigger is working:
