Halving doesn't indicate that the price will go up, its purpose is to slow down the blocks being mined and rewards cut into half. Its not 100% guarantee that the price will go up once the halving came in but if you look at the technicals and chart the short term for crypto's is bearish but in the long run im bullish due to the fact of an falling wedge pattern that's just only my speculation.
You have not studied the details of halving completely as the story of halving not ends up with cutting the reward into two but it also mean that the supply to the market will be reduced to half and the demand of bitcoin will be the same as it is so due to the reduced supply the price will increase much faster and seeing this a lot of other investors will come to invest in bitcoin which is a double benefit of halving to bitcoin.
