Losing streaks do not mean your strategy is broken. They are a mathematical certainty: even the sharpest approach hits rough patches, and the difference between professionals and casual bettors is not avoiding variance but understanding it.
Variance is the spread of outcomes around your expected result. A coin weighted to land heads 52% of the time still produces runs of four, five, six tails, and across only ten flips you might see two heads. The edge is real; a short sample hides it.
The same applies to +EV betting. A bet at odds of 2.00 with a positive edge still loses close to half the time, and losing runs across a week of such bets are routine. Value betting profits arrive through volume: judge your results over hundreds of bets, not a weekend.
Three habits keep variance survivable. Stake level and within your bank, so no single run can hurt you; the staking entry covers the framework. Save every bet you take to your +EV Bet Tracker and review the EV-band analytics, which compare expected against actual returns and show whether you are running above or below expectation. And judge each bet on the numbers at the time you placed it: a bet taken with value stays a sound bet whatever the result.
