And there is chance the LTC halving will start the alt coin season 'bull rush'. That we are all waiting for to happen.

LTC price has been moving between $80 - $100 for the past weeks, with the coming halving in 10 days, I don't think there will be much to be expected because usually, when a blockchain is expected to undergo halving, two weeks before that day is usually dump from traders as they want to have their profits before that day, the wise ones don't want to be trapped in the circle of whales games, so I don't think there is much to be expected from to that day.
Increase in Volume means lot of traders are buying and selling and it could also mean that more people are dumping where less people are buying and its always a signal that people are selling for profits and that is why despite the volume increase you said, there is no too difference in the price, it is even dumping instead of the price to appreciate, so your volume signal for price increment is not correct.
In addition, over the years, altcoin halvings don't generate much attention like Bitcoin where you will see lot of request in google search engine, demand for Bitcoin usually exceed all time during Bitcoin halving and after that period, bullrun use to commence.
