50/50 Street

[ignatus]

starting bet:

High: 3u
1st dozen: 2u
street 13-15 or 16-18: 1u

the point with this bet is to have a neutral trend (no loss) with the 1st dozen and High. Only the street will make profit. if street 13-15 is hit, street 16-18 is bet: if street 16-18 is hit, street 13-15 is bet. OK

progression:

High: 3 6 9..............................(+3u for each loss)                                 
1st dozen: 2 4 6.....................(+2u for each loss)
street 13-15 or 16-18: 1 2 3...(+1u for each loss)

+1 step in progression for each loss, keep the same bet and continue progression until reach a new high, then reset

To make sense with the progression-line another progression can be used:

Martingale for the streets, then one will be recovered with one hit. (the dozens and high is still a neutral trend, no loss)

Street:  1 2 4  8 16
Dozen:  2 4 8  16 32
High:     3 6 12 24 48


Logic says one street cannot be hit 14 times without the other being hit, this goes for the street also, so this martingale progressions with the streets should work just fine.
