IMVHO the most misunderstood part of the GoF Design Patterns book is that the good part is actually Chapter 2 ”A Case Study: Designing a Document Editor” which carries great design advice (it told us to favor composition in 1994!) & the patterns that follow are mostly a reflection of the state of C at that time.
If you skip the good part and start reading the patterns like a laundry list, it must be very confusing as to why anyone would like that book.

An Efficient deep learning model to Predict Stock Price Movement Based on Limit Order Book
In high-frequency trading (HFT), leveraging limit order books (LOB) to model stock price movements is crucial for achieving profitable outcomes. However, this task is challenging due to the high-dimensional and volatile nature of the original data. Even recent deep learning models often struggle to capture price movement patterns effectively, particularly without well-designed features. We observed that raw LOB data exhibits inherent symmetry between the ask and bid sides, and the bid-ask diffe…
