Market structure as a notion has existed for as long as there have been financial markets. The basic idea is still important. This is especially true when evaluating market movements and identifying trading opportunities.
The market structure is simple, you can see in my picture that there is a continuation in upside, and then I have put premium/discount in which will help your to see characteristics of mitigation, and I call this point called an "order flow".
After that, when the market is more complicated, we will use the liquidity concept to help. That is, without liquidity manipulation, we will not accept that it destroys the market structure.
Thank you for reading; this is my opinion (PAO_ZEN). Good luck guys :)
