// This code runs as a strategy, which cannot generate alerts.
// If you want to use the alerts it must be converted to an indicator (study).
// To do so:
// 1. Swap the following 2 lines by commenting the first and uncommenting the second.
// 2. Comment out the last 4 lines containing the strategy() calls.
// 3. Save and voilà.
