France elections

Hello,

This is my first time betting on presidential election results. I have a bet on a candidate i am expecting to lose but i want to profit on possible increase in odds on election day. It’s important for me to trade out before the market is settled. Question is: when is the last day/time of the day when i can trade out? Can i trade out on sunday during the day while french people go to vote? Or is it to late then?

Thanks
