For the two BG alarms, the direction is judged from the last two readings.

### Predictive Low Alert

The Low BG Alert can warn you *before* glucose actually goes low, based on the forecast from the looping app. In the alarm's settings, set **Predictive** to the number of minutes to look ahead in the forecast (up to 60); if any forecast value in that window is at or below the alarm's threshold, you are warned early. Set it to 0 to alert only on actual readings.

* For *Loop*, the forecast that *Loop* uploads is used.
* For *Trio*, the lowest of *Trio*'s four forecast lines (ZT, IOB, COB, UAM) at each point in time is used.
