Hello, I am new to trading, very new, I have put alot of time into youtube and reading and will do some more, but for now, im looking for help getting specific questions answered.

I know what BOS is.
I know what COCH is
I know what MSS is.
I dont know how to read a DOM
and i have yet to look into SWP swing fail pattern.
Id like to figure out how/what order blocks are.
But i still feel like im missing understanding on the basics .

So my questions are for you guys, im looking for different opinions on the same question.
What is your definition of a BOS or COCH or MSS.
Im looking at pictures and trying to understand it so i can see it easily on the charts but it just never plays out like its "supposed" to.

I know a bit about failed auction, you know, fail and gain, or upthrust, but so far it feels like im guessing.
I need more confidence. Can anyone help me understand this better?

Thanks in advance but please im not interested in any opinions on other things other than these answers. thanks
