The book's mechanisms, triggered by your own hand. Each simulator delivers one “so that's why” in sixty seconds — drag a parameter, watch the market react, then follow the link to understand why.

How one drop feeds on itself

In 60 seconds: why your liquidation order pushes price lower and kills the next tier — and how ADL comes for the profitable once the insurance fund runs dry.

In 60 seconds: how a market order walks the book — and what the same size costs you in a deep book versus a thin one.
