Hi there!
I was confused in making Short position by "SetHoldings(_symbol, -1.0);"
As you can see in the report below, there're only Long positions and liquidations. No Short positions.
How can I fix it?
Thanks!

You can only buy with the currency you have available in your portfolio. GDAX is a cash-only, long-only brokerage and doesn't support margin trading at this time.

Thanks for your reply. I found out that I can backtest Short postions by using Long positions with sign "-" at the results ))

Artem Dyner, how exactly did you backtest short positions?

GDAX is a non-margin, cash-only brokerage, which means that it is not possible to put on a short position.However, it is possible to use data from Quandl for research and to conduct a theoretical backtest, where short positions are allowed.
I've attached a backtest where I retrieve BTCUSD data from the exchange BITFINEX, using Quandl. The algorithm puts on a short position when the price is lower than the lower Bollinger Band and liquidates the position when the price crosses the middle Bollinger Band.
