Charting: 12-venue order book, open interest from 18 venues, a 2-D liquidation surface; whale board by entity

The chart aggregates the order book from 12 venues and open interest from 18, draws a two-dimensional liquidation surface, and its panes can be resized by dragging. Searching an entity re-scopes the whale board and pages its full transaction list with a coin filter. Coins can be found by name, not only by ticker, in every search box.
