When is electricity cheapest?
On dynamic tariffs, electricity is often cheapest overnight and in the early afternoon when solar lowers wholesale prices. The exact hours still change every day. The only reliable answer for "today" is the published day-ahead curve.

Typical patterns (not guarantees)
Winter evenings with heating and lighting demand are often expensive. Windy or sunny midday hours can be cheap. Negative prices can appear when renewable supply exceeds demand.
How Dnamiq answers "should I wait?"
Dnamiq compares the cost of using electricity now with the cheapest upcoming continuous window for a typical load size. If the euro difference is tiny, it says waiting is not worth it, even if a slightly cheaper hour exists.
