Hold your nerve if you hit a rough patch — remember, even the best strategy only works in the long term, so things should balance out eventually. This is a conservative betting system insofar as a long string of losses will not wipe out your bankroll as quickly as with a negative progression.
With a negative progression, you raise your bets after your losses. This is more dangerous, since a bad run of losses can wipe you out quickly. The goal for any series of bets is to win just one unit, then start a new series. Each series starts with a one-unit bet. After any win, the next bet is one unit more than the previous bet.
After any loss, the next bet is identical to the previous bet. That is, if you lose a two-unit bet, your next bet is a two-unit bet until you have a win, at which point you raise your bet one unit to a three-unit bet.
That is the whole system, except for one stipulation—Never place any bet that would result in a win for the series of more than one unit. Yet, a much shorter run of wins can get back your previous losses on a series, since you raise your bets following wins. Strings of losses hurt less, yet strings of wins pay more.
