Opening Range Breakout

This is an Opening Range Breakout script. It will plot the opening range high and low (green and red lines, respectively) as determined by the user input (default is a 15 min window from market open, 9:30 - 9:45 am). The time period for the breakout is also configured by a user input (default is from 9:45 am - 2:30 pm).

Alerts are sent for breakouts either above (bullish) or below (bearish) the opening range high and low. An EMA is also used for trend confirmation before sending alerts for breakouts (to avoid false signals).

A bullish breakout is determined by all of the following being true:
- The current price being above the opening range high (green line)
- The EMA trending up (ie the current value of the EMA > prior EMA value)
- The current price is > the EMA
- The EMA is > the opening range high

A bearish breakout is determined by all of the following being true:
- The current price being below the opening range low (red line)
- The EMA trending down (ie the current value of the EMA < prior EMA value)
- The current price is < the EMA
- the EMA is < the opening range low
