I don't see any technical which you refer, it's just a pure random line bullish trend draw. If you think high volume trading is another thing of bullish trend, just look on the previous months where Bitcoin price is below $20K, why the pump doesn't start from July last year? the volume is similar like the the last few days!

We're still 14 days in this year, there's next 351 days where Bitcoin price will down due to FUDs, government ban Bitcoin, top exchange got hacked, etc.
