i found it interesting in chapter 2.3 when they talked about masking size. when i first embarked on this journey i would see Tim talking about level 2 and i put such an emphasis on how important it was that it drove me mad. i would say oh i did this but i still need to learn how to read level 2. however my perspective has changed now i see level two and think it is just used as another indicator that is either on your side improving your odds or confirming that the hypothesis you have is wrong. mind you these thoughts have come about from listening to the steadytrade podcast i enjoy.
