Useful alert conditions are provided: "Less than low" and "Greater than high".

Configuration:

Versionsinformation:

Added lines for future: During session, uses current day's high and low and eliminates the first day in the calculation to predict what the high and low will be. When the session has finished, displays the current values as how they will be plotted in the next session.
