BTC has been in an ascending channel for a couple of weeks.
For the last 2 days, it's been making what looks so far like a bullflag, which, if it continues neatly, would end around the time price hits the bottom of the channel again.
If we break out upwards, adding the height of the flagpole would take us to ~4120, which is also the top of the channel.
Of course BTC doesn't usually follow neat patterns, but let's see.
