According to this graph, BTC is experiencing a retreat after rising up to Halving. Considering that the same thing will happen, the uptrend that started today can continue until May next year.
What retreat? It's clear that in 2012 and 2016 price exploded after the halving.
It's difficult to predict what will happen because there's very little data to depend on. Each halving was a little different and in 2012 very little people had Bitcoin so it was a micro economy.
Maybe after another 2 or 3 halvings we'll see a clear pattern.
You can see the highest rate of price rise on marked with red! Blue is the nearest time for halving. And this blue times are not BTC's all time highs. Before halving price is getting rise, and after halving started a correction.
