It looks more like it is you who have no idea how the price actually traded back then
Before the halving the Bitcoin price rose to over 750 dollars per coin due to the hype that had risen to insane levels thanks to the expectations of the coming halving. And just a few weeks before the actual event Bitcoin crashed to nearly 600 dollars since many folks had been cashing out feeling and expecting that the rest of them would in fact be cashing out after the halving. Other than that, I agree that the current rally basically started in late September-early October later that year (i.e. in the fall of 2016)
