5. The ORB strategy is based on the premise that if the price moves a certain percentage from the opening price level, the odds favor a continuation of that move until the closing price of that day. The ORB strategy suggests that long (short) positions are established at some predetermined price threshold a certain percentage above (below) the opening price, respectively. Crabel (1990). • Profitability of the ORB strategy imply that the asset price must follow so-called intraday momentum at the price threshold levels, i.e., the tendency for rising asset prices to rise further and falling prices to keep falling, Holmberg et. al. (2013). Rationale

6. The Contraction-Expansion (C-E) principle: • The principle is based on the observation that daily price movements seem to alternate between regimes of contraction and expansion, or, periods of modest and large price movements, respectively. • In particular, the prices are characterized by intraday momentum during expansion days, whereas during contraction days, prices move randomly. • As most days are contraction days an ORB strategy may be viewed as a strategy of identifying and profiting from days of price expansion and avoiding contraction days. Rationale

8. Thresholds in log, at day t, can generally be given as: and where and is the opening price at day t Strategy Returns in log, at day t, are hence given by: Strategy

T is the number of trades. freq gives the proportion of trades that result in positive returns, while A gives the average returns. The p-values are calculated based on the HAC standard errors. We find significant positive long-run profitability for some, or all, thresholds depending on the asset, and that the ORB strategy is a relative robust strategy w.r.t thresholds. Illustration

19. Day trading with opening range breakout strategies can generate value if the cost is small enough (Crabel, 1990; Williams, 1999; Holmberg et al, 2013; Lundström, 2013) • Lundström (2013) shows that the ORB profitability is linked to intraday volatility and there could be as much as 2 % differences in daily returns during high and low volatility states. Consequently, the ORB strategy should always be used in combination with volatility filters. • Although not explicitly shown here, ORB returns are uncorrelated with other strategies such as long only as well as trend following strategies, CTA or Managed Futures. Conclusion

20. Testing ORB strategy returns for other filters than volatility • Volume probably matters, see Crabel (1990) • Intraday data to study intraday trends in prices Future Research
