that was the point - the was 3 clear waves down - that could have been in the midst of a bearish wave 3 or completed an ABC move (as price was at a double bottom). That's why he focused on this chart said it's likely to gap and go down confirming a wave 3 or gap up to confirm the simple 3 wave ABC and go up

you don't have to know which way the market is going to go to make money - the important thing is to identify important areas of inflection and have a plan and execute on it - and not blame others or get emotional about it. 

see the image - that was a big inflation point - folks trading the indexes would have had a plan coming into Friday to react depending on the direction that broke. you can see the clear 3 waves down, was either going to turn into a bearish wave 3 down or complete that pullback and rally hard as a simple ABC - you don't have to know which way it will go, just react to price. However with AAPL's reaction one could have favored the simple ABC but still it didn't matter
