I told you to sell yesterday and the share price went down
What Raystock means is that a stock can only go up or down and when he waits until he sees the premarket trading he stands a better chance of guessing what the stock will do on a particular day.
Of course if you look at his track record you quickly see what a penniless paper trading loser and liar he is such as with this gem on the aapl message board

History tells you that it’s time to buy Apple again
The earning will keep going up , buy now and hold"
