Meaning of Terminologies and the Difference between the Four big ETFs and Indices

I love the way you teach. I wish you were my school teacher. My question is the terminologies that you use mostly. I know their meaning but I would like to know would do you mean by them when you are explaining charts. They are: "Hanging in," "Whippy," "Squishy," "Fading," "Choppy," "Sloppy," and "Meandering around."
My second question is, "Can we use the four big ETFs alone for market without using indices" or "Are both indices and ETFs necessary to know the state of the market?" Also, tell the difference between the two.

2nd Question: (Pat created one long video that answers both the question above along with this one)

Dear Pat, suppose you buy a long clean and simple breakout base. You buy 50% of your initial shares at the breakout. The price moves another 2.5%, you add 30%. The stock moves another 5% and you add the rest of 20%. Now, you are holding 100% of your position in a stock. After moving 5% from breakout out, suddenly it starts falling and fall back to the base. How you handle this kind of situation? Thanks a lot.
