Before the card
Identify both fighters, the promotion, date, scheduled distance and market. If the opponent changes, do not silently reuse the earlier analysis or price.
Before a transfer
Compare the deposit and withdrawal route for the chosen country. Record the network, currency, minimums and fees; never infer a missing value from another market.
Before accepting a price
Check the current quote, draw and no-contest treatment and any bonus condition. A market observation from yesterday is useful history, not an executable offer.
Afterwards
Separate the sporting result, settlement and currency conversion when reviewing costs. Do not turn one result into proof that a prediction method works.
