A very simple and effective Double Dozen strategy, played with a special Fibonacci-progression. (Recommended play with minimum stakes, that's why i play 2 DS instead of 1 Doz).
Wingoal: +100
BR/Stoploss: -200u
You alwas begin bet the single current doz hit. IF loss +1 step in the fibonacci-ladder
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377
And bet those two last hit doz, if hit -1 step in the fibo-ladder and restart procedure, (with betting the single current doz hit). IF loss +1u step in the fibonacci-ladder and restart procedure (with betting the single current doz hit)...IF zero hit, stop and wait for a hit in any dozen and +1u bet and restart procedure. Reset to 1u bet anytime you reach a new high.

I'm not satisfied with these result....
Losses 6 (6*200=1200)
Wins 14 (14*100=1400)
Total +200
Moving on, can't find any tweak except a different moneymanagement. I'll have to raise wingoal to 200u, and set stoploss at -300u, But i don't feel like testing this anymore....
