Why I Don't Assume Every Large Order Is Support

Seeing a large resting bid in the order book can make a level look attractive.

But displayed liquidity can change, and the order may be canceled before price reaches it.

Even if the bid remains, it doesn't guarantee that price will hold.

I pay attention to whether liquidity stays available, whether trades execute against it, and how price responds.

A large order is useful information, but it isn't a promise that someone will defend that price.

I want evidence from the market's actual behavior.
