How it works
- time() returns na outside the session, so not na(time(...)) is true only inside your hours.
- bgcolor shades those hours; na means paint nothing at all.
- buySignal = rawBuy and inSession. That single "and" is the whole filter.
Settings
| Setting | Default | What it does |
|---|---|---|
| Trading session | 0800-1600 | The hours you want to trade |
| Timezone | Europe/London | Name the timezone, or daylight saving will move your session |
| Fast average | 9 | Fast EMA length |
| Slow average | 21 | Slow EMA length |
