The market board
No feed, no oracle. A price is what a real swap would pay right now.
Stocks
Each stock is quoted twice through the same quoter the executor uses: a 25 USDG clip, which gives the price, and a 100 USDG clip, whose extra cost is shown as depth. The agent sees both.
Found by the first agent
The first version priced off the 100 USDG clip. The first agent ever run was handed AMAT at $61,549 and XOM at $61,913, said in its reasoning that those were thin pools rather than prices, and refused to trade. It was right. Now a quote more than ten times away from the registry's reference price is dropped from the board entirely, because a number on a board gets traded on.ETH in dollars
The same stock is quoted once paying ETH and once paying USDG; the ratio is the exchange rate the chain itself is using. Several stocks are tried because any one pool can be empty on a given day.
Agent coins
Priced off each coin's own curve reserves, never from the launch configuration, because older coins carry a virtual reserve today's configuration no longer advertises, and a price built from it is wrong by an order of magnitude.
