Sportsbook odds can change quickly. This is very common in ValueBet.
You may find a bet in the Straight ValueBet Tool, open the sportsbook, and see that the odds are different from the ones shown in NinjaBet.
Sometimes the odds are slightly lower. Sometimes they are much lower. Sometimes they are higher. Sometimes the market is no longer available.
When this happens, the most important rule is simple:
Do not place the bet using old information.
A ValueBet exists because the sportsbook odds are higher than the estimated Fair Odds. If the sportsbook odds change, the EV changes too. This means you should always update the odds, recalculate the bet, and place it only if it still has positive expected value.
Why odds change
Odds can change for many reasons. For example:
- other users placed bets on the same selection;
- the sportsbook adjusted the price;
- the market moved;
- team news or player news changed the price;
- the event is getting closer;
- the sportsbook corrected a stale price;
- the sportsbook limited or removed the market.
This is normal. ValueBet opportunities can disappear quickly because they are based on prices that appear higher than the estimated fair value.
If the sportsbook corrects the price before you place the bet, the value may become smaller or disappear completely.
The most important rule
If the odds change before you place the bet, you must not automatically place the bet. You should first check whether the bet still has value.
The process is:
- Check the new sportsbook odds.
- Enter the new odds in the ValueBet Calculator.
- Compare them with the Fair Odds.
- Check the updated EV.
- Place the bet only if the EV is still positive and the stake is acceptable.
Do not place the bet only because it was previously shown as a ValueBet. The old EV is no longer valid if the odds have changed.
If the odds are lower
This is the most common situation. For example, NinjaBet shows:
- Fair Odds: +100
- Sportsbook Odds: +120
But when you open the sportsbook, the odds are now:
- Sportsbook Odds: +105
The bet may still have value, but the value is smaller. You should enter the new odds in the calculator and check the new EV.
If the EV is still positive and the stake is accepted, you can decide whether to place the bet. If the EV is too low or negative, skip the bet. Do not force the bet just because it was good a few seconds earlier.
In ValueBet, the price is the reason for placing the bet. If the price is no longer good enough, the bet should be ignored.
Common mistakes to avoid
Placing the bet without recalculating
If the odds changed, the old EV is no longer valid. Always update the calculation before placing the bet.
Accepting a lower price automatically
A lower price may still have value, but it may also remove the value completely. Check the updated EV before deciding.
Ignoring small odds changes
Even a small odds change can affect EV, especially when the original edge was small. If the odds have moved, update the calculator.
Comparing the wrong market
Do not compare the Fair Odds of one market with the sportsbook odds of another market. The event, market, selection, and settlement rules must match.
Using the old suggested stake
If the odds change, the suggested stake may also change. Recalculate the stake before placing the bet.
Not recording the actual odds
If you place the bet, record the real odds you accepted in the Bet Tracker. Do not record the old odds from the tool if the sportsbook odds were different. Your analysis will only be accurate if the tracked data is correct.
Final summary
Odds changes are normal in ValueBet.
When sportsbook odds change before you place the bet, you should stop and recalculate.
To handle odds changes correctly:
- Check the new sportsbook odds.
- Make sure the event, market, and selection are the same.
- Enter the new odds in the ValueBet Calculator.
- Check the updated EV.
- Check the suggested stake again.
- Confirm that the sportsbook accepts the stake.
- Place the bet only if the updated EV is still positive.
- Record the actual odds in the Bet Tracker.
Do not place a bet using old odds. Do not force a bet if the value has disappeared.
The goal of ValueBet is not to place every opportunity you see. The goal is to place only the bets where the price is still favorable at the moment you actually place the bet.
