 There's a lot going on.🥵
 
-To match the author's description, we first set up `layers`. We use the `tclf` implementation of the [tradesize](https://github.com/KarelZe/tclf/blob/main/src/tclf/classical_classifier.py#L336), [quote](https://github.com/KarelZe/tclf/blob/main/src/tclf/classical_classifier.py#L154), and [depth rule](https://github.com/KarelZe/tclf/blob/main/src/tclf/classical_classifier.py#L362C1-L363C1), as well as [reverse tick test](https://github.com/KarelZe/tclf/blob/main/src/tclf/classical_classifier.py#L137). The subset named "ex" refers to exchange-specific data, "best" to the NBBO and "all" for inter-exchange level data. Identical to the paper, the reverse tick test is applied at the inter-exchange level, due to the devastating results of tick-based algorithms at the exchange level. The authors perform random classification on unclassified trades, hence we choose `strategy="random"`.

-The calculation of the [depth rule](https://github.com/KarelZe/tclf/blob/main/src/tclf/classical_classifier.py#L362C1-L363C1) requires the columns `ask_{subset}`, `bid_{subset}`, and `trade_price`, as well as `ask_size_{subset}`, `bid_size_{subset}` and `trade_size`.

 As there is no `{ask/bid}_size_best` at the NBBO level (`subset="best"`), I copy the columns from the trading venue. This allows us to mimic the author's decision to filter for mid-spread at the NBBO level, but classify by the trade size relative to the ask/bid size at the exchange.
