42. Market-watch tools

Pro odds: the sharp reference

The Pro odds page turns the theory of chapter 15 into an instrument: it cleans the sharp bookmaker’s prices of the margin, computes fair odds and fair probability for upcoming matches, then shows at what minimum odds it would even make sense to talk about the given outcome at all. If a stored bookmaker price gives a greater theoretical EV than the threshold (2% by default) relative to the fair price, the row gets a price-deviation flag, on goal, corner and BTTS markets besides 1X2. The flag measures the gap between a stored price and the reference; it is not a promise of profit: as chapter 13 measures, the closing price is more accurate than our models.

At the bottom of the page a paper-trail report tracks the afterlife of the signals: how many signals there were, how many settled, the hit rate, the ROI and the EV at the closing price, with a pre-set go/no-go gate. If the gate is formally met but the realised return is nonetheless bad, the page states it in a red box. This is the methodology of chapters 11–12 on live data: the benchmark is not the weekend profit but the closing price.

Market-movement radar: which way is the market repricing?

The radar ranks the biggest shifts of the consensus odds (the average of at least three bookmakers) of upcoming matches since the opening line, by the change in implied probability. It is a purely descriptive instrument: it shows where the market has worked, not what you should do. For the interpretation chapter 13 gives the language: shortening odds mean an increasing priced-in probability, and toward the closing line the market gets ever smarter.

Arbitrage watcher: surebet maths on live data

The arbitrage page runs the formulas of chapter 19 on the stored prices: if the combined implied probability of the best odds falls below 1, it shows the legs on a card, the stake distribution per 100 units and the theoretical profit. It is explicitly an educational view: you see what a real surebet looks like, and along with it the practical pitfalls too — a stale price, vanishing odds, limiting.

Two rules for every market-watch tool

The bookmakers appear with an anonymous label ("Bookmaker A", "Bookmaker B") for regulatory reasons. More important than this: every signal refers to the stored price, which can be several minutes old — before betting you must always check the live price, because the soft bookmakers quickly fix the erroneous price and limit the winning profile (chapter 16).

These pages are measuring instruments, not tip buttons. They show how the market works and how much it would cost to play against it — the decision and the responsibility are yours.
