My 2c - a depth chart on an order book is only relevant in the immediate short term, i.e. if you're looking to optimize your buy/sell bid/offer in the next few minutes. In reality, if there are fundamentals driving the price one way or another bids/offers adjust almost immediately to match. I've seen (at least in cryptos) massive buy walls crumble downward in seconds as sellers adjust down and vice versa.
Thanks, I was slowly coming to this conclusion, i.e. you want to buy (or sell) and need an indication of if and how long your order should more or less take to fill.
