1. Source: the full history of every match's odds and limits up to kickoff. We never see bet slips — only the prices the bookmaker shows everyone.
2. How far a move goes depends on the limit. The same bet shifts a low-limit niche league a lot and barely nudges the Champions League. That is why niche amounts are smaller — but every bet there shows.
3. The winner (1X2) and the handicap are shown as one market — the “side” of the match. The bookmaker prices them together, so the prices cannot tell whether money went on 1X2 or on the handicap. Over/Under is counted separately.
4. We filter out noise: small back-and-forth price corrections the bookmaker makes on its own do not count as money.
5. Sudden reprices after news (line-ups, injuries, walkovers) are shown on the timeline but not counted in the amounts — they are not bets.
6. A limit change without a price move is the bookmaker's schedule, not money. We count only until kickoff.

Amounts are indicative. Trust the order of matches, the side the money is on and the timing of the inflow more than the amount itself.
