You bet in strings of three. If up stay at base level. If down, move up to next level. Play out strings of 3 no matter what. If at the end of a string of 3 you are up, go back to base level. If at the end of a string of 3 and you won all 3 but are still down, move up to next level. Keep moving up after 3 bets until you reach a new high.
On a test shoe I won 5 units, not bad
