How it works
- request.security reads high[1] and low[1] from the daily timeframe, so the levels are yesterday's finished values.
- lookahead is only safe here because of the [1]: the script never uses data from an unfinished day.
- Create an alert on "Previous Day Levels" and pick "Broke yesterday's high" or "Broke yesterday's low".
Settings
| Setting | Default | What it does |
|---|---|---|
| High colour | green | Colour of yesterday's high line |
| Low colour | red | Colour of yesterday's low line |
