### When does Automatic Dosing Happen

Automatic dosing only happens when closed-loop is enabled in the settings screen.
Automatic dosing only happens when <code>Closed Loop</code> is enabled in the settings screen.

Loop generates a glucose prediction over the next 6 hours (the duration of insulin action), which is why the predicted glucose plot is included on the bolus screen. Loop considers glucose prediction with respect to your scheduled <code>Correction Range</code> over the full DIA, weighting closer predictions more than later predictions, when calculating [Recommended Bolus](../algorithm/bolus.md).

It is actually easier to answer when Loop will **not** automatically increase insulin delivery. In these cases, the prediction at the end of the DIA can be significantly higher than your <code>Correction Range</code> but no automatic dosing will happen:

* If at any time in the next 3 hours, Loop predicts glucose below <code>Glucose Safety Limit</code>, <code>Temp Basal</code> is immediately set to 0.0 U/hr and recommended bolus is set 0 U
* If the prediction dips below the low-end of your <code>Correction Range</code>, there is no **automatic** delivery
* If the current IOB is two times the <code>Maximum Bolus</code> setting, there is no **automatic** delivery
In the situations listed below, the prediction at the end of the DIA can be significantly higher than your <code>Correction Range</code> but no automatic increase in insulin delivery will occur:

* If at any time in the next 3 hours, Loop predicts glucose below <code>Glucose Safety Limit</code>, <code>Temp Basal</code> is immediately set to 0.0 U/hr and recommended bolus is set 0 U
* If the prediction dips below the low-end of your <code>Correction Range</code>, there is no **automatic** increase over scheduled basal
* If the current IOB is two times the <code>Maximum Bolus</code> setting, there is no **automatic** increase over scheduled basal

Even in cases where Loop does not automatically dose, the recommended bolus might be positive, which you see if you tap on bolus icon manually.
