My guess is the halving itself will be quite non-eventful
The last time there was not much movement in price. There was just a lot of talk.
Price on the day of halving went from about $12.20 to $12.35.
Exactly one year later the price was over $1,100.
Actually, 4-5 months later it peaked at
$1100 $266, but you must be aware that price doubled 2 months after halving and tripled 3 months after halving. I think that this time the change will be even faster, because mining is way to more competitive compared to 2013, miners have to dump as soon as they mine the BTC if they want to stay in game.
