A genuine edge does not mean a smooth line upwards. This works out what a run of bets really looks like: the expected profit, how far either side of it you should expect to land, and the odds of sitting in the red even when everything is going right.
Betting advice talks about expected value and stops there. What actually ends bettors' careers is the distance between the average and the path: the eleven-loss streak, the month at minus 20 units, the moment the plan stops feeling true. Knowing the size of a normal downswing in advance is what lets you sit through one.
Each bet returns either the profit at your odds or minus your stake. From your win rate and price we take the mean and standard deviation of a single bet, scale them across the run (the mean by N, the spread by the square root of N), and read the chance of finishing below zero from the normal approximation. The expected longest losing streak comes from the standard result for the longest run in a sequence of independent trials.
Two honest caveats. Real betting is not perfectly independent, since correlated picks and shared market moves cluster losses more tightly than this assumes, and the normal approximation is loose for small numbers of bets. Treat the output as the right order of magnitude, not a promise.
Longer than most people expect. Over 500 bets at a 55 percent win rate, a run of seven or eight consecutive losses is entirely normal, and longer streaks are far from rare. A losing streak is not evidence that a strategy is broken.
Yes. With a small edge, the chance of sitting in the red after a few hundred bets is often well above one in five. That is why sample size matters more than any single month.
Stake flat and small, bet singles rather than accumulators, and increase the number of bets. You cannot remove variance, only make each bet a smaller share of the whole.
For a modest edge with flat one-unit stakes, drawdowns of 15 to 30 units over a long season are ordinary. Size your bankroll so that the drawdown you can survive is comfortably larger than the one you expect.
