RoHo

A new Go-language client library for accessing the Robinhood API. Based on https://github.com/andrewstuart/go-robinhood

Features

• Idiomatic Go API
• Buying & selling shares and cryptocurrencies
• Access to historical quotes & crypto positions
• Common interface for trading strategies
• Designed for use by trading bots

Library Usage

// Login to Robinhood. Uses $RH_USER and $RH_PASS environment variables by default
r, err := roho.New(&roho.Config{})

// Lookup the SPDR S&P 500 ETF Trust
i, err := r.Instrument("SPY")

// Buy SPY at $100
o, err := r.Buy(i, roho.OrderOpts{Price: 100.0, Quantity: 1})

// Uh oh! Cancel this order ASAP!
o.Cancel()

For a runnable example, see cmd/example.

Trading Strategies

RoHo now ships with a pkg/strategy library to define and execute basic trading strategies.

NOTE: You will lose money if you use RoHo's trading strategies feature

Here is a simplified example from the hilo example strategy, to buy low, sell high:

func (cr *HiLoStrategy) Trades(_ context.Context, cs map[string]*CombinedStock) ([]Trade, error) {
	ts := []Trade{}

	for url, s := range cs {
		p := s.Position

		if p == nil {
			ratio := s.Quote.BidPrice / s.Fundamentals.Low52Weeks
			if ratio < 1.01 {
				ts = append(ts, Trade{
					InstrumentURL: url,
					Symbol:        s.Quote.Symbol,
					Order:         roho.OrderOpts{...},
				})
			}
			continue
		}

		ratio := s.Quote.BidPrice / s.Fundamentals.High52Weeks
		if ratio > 0.99 {
			if p.AverageBuyPrice < s.Quote.BidPrice {
				continue
			}

			ts = append(ts, Trade{
				InstrumentURL: url,
				Symbol:        s.Quote.Symbol,
				Order:         roho.OrderOpts{...},
			})
		}
	}

	return ts, nil
}

You can run these strategies by using cmd/matador
