The decision log
Every decision the pricing engine makes is recorded with the market as it looked at that moment: the median, the occupancy, the depth behind it.
That snapshot is the point. A price you cannot explain a week later is a price you cannot defend, and “the algorithm said so” is not an answer when a machine has been idle for four days.
What an entry tells you
Section titled “What an entry tells you”- What was suggested and, if applied, what was set.
- Which rule produced it and what its bounds were.
- The market at that moment — not today’s market, which is what makes the entry still readable later.
- Or why nothing happened, in the same feed. A rule that stayed silent is an entry too, with the reason.
Reading it
Section titled “Reading it”Suggestions start appearing once a rule covers a listed machine and the market has enough offers. Both halves matter: a rule over an idle machine has nothing to price, and a rule over a thin market deliberately produces nothing.
Using it before you trust it
Section titled “Using it before you trust it”The most useful way to start is to leave rules on and apply nothing. After a few days the log answers the only question that matters: would this rule have made you money, or would it have chased the market down?
