## When to prefer this

Use this endpoint when you specifically need whale or institutional order flow data for tokenized stocks trading on Robinhood Chain, particularly to confirm smart money direction before entering a position or to detect unusual large-trade activity on tokenized equities. Prefer this over generic price or volume endpoints when the user question is about who (large players, whales, institutions) is moving a tokenized stock, not just what price it is at.
