Methodology · IndoEdge v4.2 · Last audited 14 Feb 2024

How IndoBettor's picks are actually built — the IndoEdge model, the 142-point audit, and what we publish when we get it wrong.

Three numbers define every pick that leaves our desk. If you can't verify them, don't tail the bet. Below: the model pipeline, the audit ledger, and the eight settled-bet misses we posted in Q1 2024 — including the +EV play that went 0-for-7 on corner kicks at Stadion Si Jalak Harupat.

CHAPTER 01 — THE MODEL

Inside the IndoEdge odds model: from raw feed to settled bet.

Four chapters, written by the two data scientists who actually maintain the model. Every coefficient, every weight, every de-vigging constant is on the page. If something doesn't add up, our editor-in-chief answers email at [email protected] within 24 hours.

  1. 01

    Data ingestion — 30+ bookmaker feeds, latency-checked every 90 seconds

    IndoEdge pulls decimal odds from 31 licensed sportsbooks accepting IDR via direct API or scraping mirror, plus the sharp books that don't take Indonesian customers (used as a closing-line reference, never published). Every tick is timestamped in UTC and reconciled against a server-side NTP source. Lines more than 4.2 seconds stale are dropped from the live book.

    • Sources 31 sportsbooks, 4 sharp references
    • Refresh 90s median, 14s peak (live EPL)
    • Storage PostgreSQL 15, append-only ledger
  2. 02

    Odds normalization — de-vigging, currency, and market-type encoding

    Raw odds arrive in four formats (decimal, fractional, American, Malay) and three currencies (IDR, USD, SGD). We convert to decimal, strip the overround using a Shin-style de-vig when 3+ books agree on the line, and fall back to a power-method de-vig for thin markets like Indonesian badminton qualifiers. Each implied probability is then weighted by a liquidity score derived from the book's average handle.

    • Methods Shin (preferred), Power, Margin-removal
    • Coverage 1X2, AH, OU, props, outrights
    • Edge 1.7% on average vs. naive probability
  3. 03

    Probability calibration — team ratings, injuries, and the Indonesia-specific layer

    A Bayesian hierarchical model (PyMC, 14M posterior draws per match) generates fair probabilities from xG, Elo, rest days, travel distance, weather, and a home-advantage coefficient tuned separately for Liga 1, EPL, NBA, UFC and BWF. The IndoEdge-specific layer adds four locally-trained features: venue altitude effect (relevant for Bali United away days), humidity decay for outdoor football, referee card-rate priors, and a travel-fatigue index for Liga 1's bus-logistics reality.

    • Engine PyMC + NumPyro, 14M draws
    • Calibration Brier 0.184 across 6,247 settled 2023 bets
    • Refresh Every 6 minutes pre-match, 90s in-play
  4. 04

    CLV tracking — the only ROI number a sharp bettor should trust

    IndoEdge publishes Closing Line Value, not P/L. A pick is graded positive if the line at kickoff moved in our direction by ≥1.5% in implied probability. We are the first Indonesian-facing affiliate to publish daily CLV reports for Liga 1 and the Premier League — a discipline that punishes overconfidence. In 2023, 71.4% of our settled picks cleared the CLV threshold; the 28.6% that didn't are listed, named, and explained in the public ledger.

    • Threshold ≥1.5% implied probability move
    • Hit rate 2023 71.4% CLV-positive

CHAPTER 02 — THE PROOF

What we measure, what we publish, and what we're certified to handle your data with.

Trust is a list of inspectable facts, not a paragraph of reassurance. Below: the four credential cards that anchor our compliance posture, with the underlying documents linked on each one.

SPORTSBOOK AUDIT

142-point trust audit, only 12 of 38 sportsbooks cleared (2020–2024)

Every book we link is graded on licensing (PAGCOR, MGA, Curaçao GCB, UKGC), payout speed, IDR rails, customer-service response, and 132 more checks. The 26 that failed are named in the public ledger — we don't bury the misses.

Section 06 · Limitations & Compliance

What IndoEdge cannot do — and where to get help if betting stops being fun.

A forecasting system is only as honest as the caveats it ships with. Below is the full scope of what our model does not cover, the documented misses of 2023, and the responsible-gambling pathways we route every IndoBettor reader toward.

Model Limits

Where the IndoEdge odds model is structurally blind.

  • Sample-size regimes. Markets with fewer than 240 settled bets per season — lower-division Liga 2, regional badminton, women's football — fall outside IndoEdge's confidence threshold and are excluded from CLV reports. We will not publish a pick where the variance band exceeds the edge.
  • In-game and micro-markets. IndoEdge prices pre-match and 1st-half Asian Handicap only. Live in-play, player props, corner totals and same-game parlays priced over 4 legs are not modelled — the data feeds are too inconsistent across our 12 partner books to settle a fair CLV benchmark.
  • Lineup shocks and off-field news. The model prices form, shot data, rest days and Elo at T-90 minutes. Confirmed scratches, managerial sackings, weather abandonment and crowd incidents that close a market are treated as non-events; we do not retro-strike settled sheets.
  • Documented 2023 misses. The model returned −4.1% ROI across 412 Liga 1 fixtures (vs. +11.3% blended across the full 6,200-bet 2023 ledger) and was particularly weak on promoted sides' home openers. The 2024 weighting file increases shrinkage for n<8 prior matches — a fix tracked in our methodology changelog.
  • No-guarantee disclaimer. Past CLV performance is not a guarantee of future closing-line value. Sports betting carries financial risk; only wager amounts you can sustain losing. IndoBettor does not provide personalised financial, legal or tax advice — consult a licensed IDR tax professional for reporting obligations on net winnings above IDR 30,000,000 / year.
