Polls close at 7pm except in larger cities, but counting of votes start at this time. It's forbidden to leak the results until 8pm, at which time the sample is large enough to give a precise estimate, unlikely to move by much.
Estimate of voting booth all around. Probably gonna shift a bit until midnight but not by much and surely not enough to modify the results; and so far it seems Macron is going from 65.1 to 65.5.
