1800 BTC per day is a lot. In 256 days we will have only 900 new btc per day, which is quite interesting and will certainly impact the price.
It is hard to price in a halving before it occurs, because it affects the supply of bitcoin on exchanges.
1000000 BTC are traded every day. A change of only 900 is not going to have any impact. The halving does not lower the supply. The supply is always increasing.
It is interesting to note that while there is a common myth among Bitcoiners that a halving causes an increase in price, Litecoiners have a myth that says that a halving causes a decrease in price!
