Live futures spreads off one client, and the master's max entry spread

One quote feed per machine: a TopstepX client's market hub, else a
Tradovate client's market-data socket, subscribed to every listed root's
front month and the drain micro. A supervisor keeps it on a working client,
dropping one that fails or goes quiet while the market trades.

The Auto draw weighs each instrument by its live spread (the typical tick
when no fresh quote is at hand). No futures entry pays more than the
master's max entry spread ($15 until set) to cross the book: the draw
leaves such an instrument out, an explicit symbol sits the tick out, and
fireLeg and the extra-day trade check it last before sending. The Settings
page and the master's stats show the live spreads and the feed.
