If you want to know if a stock is going to increase look at the bid book for K’s. You want to see all of these in K. If not that means there probably more sells on his book than they can fill so bids will be going lower to fill that need. If it’s all K’s then book is balanced with buy/sell and more likely to keep increasing. Liquidity does matter tho because with low liquidity a large order can flip the book around. Maybe this will help a little tho in premarket on telling when and if you should buy.
