In the main loop - where Uptrend and Dntrend are calculated, if one exist (not EMPTY_VALUE) for i and the other for i+1 build object arrow on time[i+1]. You can later base an alert/notification/something else on the arrow.

Or (better) add another buffer - arrows, and assign non-empty value on above described change and empty for all others. And use object (for alert) only for bar before last change (the existence of an object can help you not repeat the alert on every tick).
