Probably not. Losing streaks are a normal part of ValueBet, even when every bet was placed at a good price. Value is about the price, not certainty: an outcome with fair odds of +100 still loses about half the time, and a bet with a 30% chance loses most of the time even when the odds are generous. The question to ask isn't "did it win?" but "was it placed at a good price?". Keep stakes consistent and small enough that a run of losses doesn't damage your bankroll.

Most people should start with quarter Kelly or half Kelly. Quarter Kelly uses 25% of the full Kelly stake: smaller stakes and smoother swings, a good starting point. Half Kelly uses 50%: more aggressive, for users comfortable with bigger swings. Full Kelly is mathematically aggressive and can be hard to live with during losing streaks. Custom Kelly lets you set your own fraction. Treat the suggested stake as a guide: you can apply it, reduce it or choose your own. Read more: Bankroll and Kelly

Open Staking in the ValueBet tool and fill in three settings: Bankroll: the money you dedicate to ValueBet Kelly fraction: how aggressive the stakes are compared to full Kelly Max stake (% of bankroll): a cap on any single stake From then on the tools suggest a stake for each bet. The cap is your safety net: with a $1,000 bankroll and a 5% max stake, no suggestion goes above $50, even when the EV looks very high. Read more: Bankroll and Kelly

ValueBet needs a larger bankroll than matched betting, because results swing. Our agents suggest from several hundred to a few thousand dollars, depending on your stake size. Whatever the amount, treat it as money set aside only for ValueBet, and stake a fraction of it in proportion to the edge so that a normal losing streak doesn't hurt you. You can enter your bankroll in the ValueBet tool's Staking settings, and the tools then suggest stakes for you automatically.

Yes. Odds are shown in American format by default on ninjabet.com, and you can switch to decimal in My Account → Settings → Odds format. The change applies everywhere: the tools, the calculators, Parlay Finder and the Bet Tracker all follow it, both for how odds are shown and how you type them. The setting is saved on your account, so it follows you on every device. Each change saves by itself; look for the Saved confirmation.

Enter the sportsbook odds, the fair odds and your stake. The calculator then shows whether the EV is positive or negative, the EV %, the expected value in money, the potential profit, the implied probability and a suggested stake. Example: fair odds +100 against sportsbook odds of +120 give positive EV; fair odds +100 against −110 give negative EV, so you'd skip that one. The result is only as good as what you type: the fair odds must be realistic and the sportsbook odds must match what's on offer right now. Read more: ValueBet Calculator

MarketOdds starts from the fair price instead of from a ready-made opportunity. It lists events, markets and selections with their Fair Odds, so you can check a price you found yourself. Find the selection, click the row to open the ValueBet Calculator with those Fair Odds already in, then type the sportsbook's odds. Higher than the fair odds means positive EV; lower means you skip it. In short: Straight ValueBet shows bets that already have value, while MarketOdds helps you verify any price by hand.

Usually less than on a single ValueBet. Parlays have higher variance because every leg must win, so you can lose several good parlays in a row before one lands. If your normal straight stake is $10, the same amount on a high-odds parlay may be too much. The more legs and the higher the total odds, the more careful you should be. Common mistakes: adding too many legs, adding selections with no real value, confusing high odds with high value, and judging the strategy after only a few parlays. Read more: Parlays in ValueBet

It combines the legs the same way a sportsbook does, then compares the result with the combined fair odds. Each leg is converted to decimal, the decimals are multiplied and the total is converted back to American. For example, +120 (2.20) and −110 (1.91) give 4.20, which is +320, so a $10 parlay returns $42. That $32 is the potential profit if every leg wins. The EV is a different thing: it tells you whether the combined price beats the combined fair odds. If each leg has value, the parlay has value too. Read more: ValueBet Parlays

Begin with straight bets. They are easier to understand, easier to track and easier to evaluate over time. A straight ValueBet is one selection at one sportsbook. A parlay combines several selections and wins only if every leg wins, so it pays more when it lands but loses more often and swings much harder. That's why the tools are separate: Straight for single ValueBets, Parlays for value parlays. Move to parlays once you're comfortable with the ups and downs of singles. Read more: Straight ValueBet

Only if it still has value at the new price. The old EV stops being valid the moment the odds change. Enter the new odds in the ValueBet Calculator, compare them with the fair odds and check the updated EV and suggested stake. Place the bet only if the EV is still positive and the stake is accepted. Example: fair odds +100, the tool showed +120, the sportsbook now shows +105. There may still be some value, but less. If you do place it, record the odds you actually got in the Bet Tracker.

Open the sportsbook and make sure everything matches the row: the event the date and time the market the selection the odds the maximum stake it accepts This matters because odds change quickly: a bet that looked valuable in the table may no longer be valuable once the price has moved. If something is different, recalculate or skip it rather than forcing the bet. Read more: Straight ValueBet

Not necessarily. A higher EV means a stronger edge, but it isn't the only thing that matters. A slightly lower EV on a clear, easy-to-place bet is often better than a very high EV that disappears quickly or is hard to verify. Very high EV can also come from stale odds or a pricing mistake, so check those rows even more carefully. Before betting, look at the sportsbook, the odds, the fair odds, the market, the selection, the last update and whether you can really place the stake. Read more: Straight ValueBet

Use the filters to keep only what's useful to you. You can filter by sport, date, sportsbook, bet type, odds range, EV range, event and competition, and also straight from the column headers. Common setups: only the sportsbooks where you already have funds, sports you understand, events starting today, a minimum EV and an odds range you're comfortable with. You can also search for an event or hide the events and competitions you don't want to see, so the table stays focused. Read more: Straight ValueBet

The table is shorter by design. The tools read the fair odds live and list only markets where the worldwide market prices both sides with real volume behind them. A thin market, or one whose prices sit far apart, gives no fair price, so it is left out rather than shown with a number you couldn't trust. Fewer rows, but each one rests on a price the market actually supports. Read more: Do value bets work? How fair odds and EV are calculated, and our members' results

Each row is one possible single bet at one sportsbook: Sport, Date and Event: what and when EV: the expected value of the bet Sportsbook and Bet: where to bet and the selection Odds: the sportsbook's price Fair Odds: the estimated fair price of the selection Last Update: how recently the odds were refreshed EV and Fair Odds tell you why the row is a ValueBet. Last Update matters because odds move fast, but still check the price on the sportsbook before betting. Read more: Straight ValueBet

If you're new or still have welcome offers to do, start with Matched Betting: the profit comes from bonuses, the math is settled before you bet, and it needs the smallest bankroll. ValueBet is for advanced users. Single bets win or lose and the edge shows over hundreds of bets, with real variance in between, so it needs bankroll discipline, record keeping and patience.

There's no fixed figure: your expected profit is roughly the total amount you stake multiplied by the average EV of your bets. For example, $1,000 staked at an average 3% EV has an expected profit of about $30; $5,000 at 5% is about $250. The real result can be higher or lower, and you can be down over a short spell. What moves the number: your bankroll, stake size, how many bets you place, how many sportsbooks you can use, account limits and how fast you get the price shown.

A value bet has a positive expected value: it is expected to make money over many bets, not on every bet. Members have recorded their value bets in the Bet Tracker since 2024, and the public ValueBet results page, updated daily, shows their settled singles: totals, profit and ROI, the month-by-month curve and the share of months in profit. Read it with care: the bets are self-reported, losing months happen, and past results promise nobody a profit. Your own outcome depends on your sportsbooks, your stakes and your discipline.
