Example: Maintaining Local State

// Local state for match odds
const matchOdds = {};

function initializeOdds(matchId) {
  matchOdds[matchId] = {
    live1x2: null,
    liveOU: null,
    liveAH: null,
    liveAsianCorners: null,
    live1hAH: null,
    live1hGoals: null
    // ... other markets initialized to null
  };
}

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);

  if (msg.type !== 'odds_update_realtime') return;

  const matchId = msg.matchId;

  // Initialize if first update for this match
  if (!matchOdds[matchId]) {
    initializeOdds(matchId);
  }

  // Apply delta updates
  msg.data.changedOdds.forEach(change => {
    const oldValue = matchOdds[matchId][change.market];
    matchOdds[matchId][change.market] = change.value;

    console.log(`[${matchId}] ${change.market}: ${oldValue} → ${change.value}`);
  });

  // Now matchOdds[matchId] contains the current state
  console.log('Current odds:', matchOdds[matchId]);
};

Example: Tracking 1X2 Movement

const oddsHistory = {};

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);

  if (msg.type !== 'odds_update_realtime') return;

  msg.data.changedOdds.forEach(change => {
    if (change.market === 'live1x2') {
      const matchId = msg.matchId;
      const [home, draw, away] = change.value.split(';').map(parseFloat);

      // Initialize history
      if (!oddsHistory[matchId]) {
        oddsHistory[matchId] = [];
      }

      // Record change with timestamp
      const lastEntry = oddsHistory[matchId][oddsHistory[matchId].length - 1];
      oddsHistory[matchId].push({
        ts: msg.ts,
        home,
        draw,
        away,
        homeChange: lastEntry ? (home - lastEntry.home).toFixed(2) : 0,
        awayChange: lastEntry ? (away - lastEntry.away).toFixed(2) : 0
      });

      // Detect significant movement
      if (lastEntry) {
        const homeMove = home - lastEntry.home;
        const awayMove = away - lastEntry.away;

        if (homeMove < -0.10) {
          console.log(`ALERT: Home odds dropping significantly (${homeMove.toFixed(2)})`);
        }
        if (awayMove < -0.10) {
          console.log(`ALERT: Away odds dropping significantly (${awayMove.toFixed(2)})`);
        }
      }
    }
  });
};

Example: Real-time Odds Display

function parse1x2(value) {
  if (!value) return { home: '-', draw: '-', away: '-' };
  const [home, draw, away] = value.split(';');
  return { home, draw, away };
}

function parseOU(value) {
  if (!value) return { over: '-', under: '-', line: '-' };
  const [odds, line] = value.split('|');
  const [over, under] = odds.split(';');
  return { over, under, line };
}

function parseAH(value) {
  if (!value) return { home: '-', away: '-', handicap: '-' };
  const [odds, handicap] = value.split('|');
  const [home, away] = odds.split(';');
  return { home, away, handicap };
}

ws.onmessage = (event) => {
  const msg = JSON.parse(event.data);

  if (msg.type !== 'odds_update_realtime') return;

  msg.data.changedOdds.forEach(change => {
    switch (change.market) {
      case 'live1x2':
        const m1x2 = parse1x2(change.value);
        console.log(`1X2: ${m1x2.home} | ${m1x2.draw} | ${m1x2.away}`);
        break;

      case 'liveOU':
        const ou = parseOU(change.value);
        console.log(`O/U ${ou.line}: Over ${ou.over} | Under ${ou.under}`);
        break;

      case 'liveAH':
        const ah = parseAH(change.value);
        console.log(`AH (${ah.handicap}): ${ah.home} | ${ah.away}`);
        break;
    }
  });
};

Comparison: ODDS vs ODDS_REALTIME

Feature	ODDS	ODDS_REALTIME
Update frequency	15-30 seconds	Real-time
Data sent	Full snapshot	Delta only
Bandwidth usage	Higher	Lower
State management	Not required	Required
Plan availability	ULTRA, MEGA	MEGA only

Best Practices

1. Maintain local state: Keep a local copy of odds and apply deltas

2. Handle reconnections: On reconnect, subscribe to ODDS first for a full snapshot, then switch to ODDS_REALTIME

3. Combine channels: Use ODDS for initial state and ODDS_REALTIME for updates

4. Track history: Store odds history if you need to analyze movement patterns

5. Handle null values: Some markets may not be available for all matches

Notes

• Only changed markets are included in each message

• An empty changedOdds array means no changes (rare, but possible)

• For a complete snapshot, use the ODDS channel

• This channel requires client-side state management

• Odds changes can be frequent during live matches, especially near key events
