Procedure: Divide the carpet into High and Low, Then Track each 3 Doublestrets hit Separately within H or L.
TRIGGER: As soon as 1 DS hit 2 times *Without the other 2 DS within that particular H or L being hit* You bet the 2 unhit DS AND you also bet 1u on the opposite Dozen (1 or 3)
for an example (DS 1-6)
High DS | Low DS
6 1
4 <--- 2
4<-Trigger 3
1
3
1
Now, DS 4 has hit 2 times without DS 5 & 6 being hit. Therefore you bet 1u on DS 5 & 6 AND 1u on DOZ 1.
Another example
High DS | Low DS
4 1<--
5 1<--Trigger
6
Now, DS 1 has hit 2 times without DS 2 & 3 being hit. Therefore you bet 1u on DS 2 & 3 AND 1u on DOZ 3.
Doubledragon is a 50/50 bet, so use any progression you like. (in my example i used a simple martingale)
First Live-session.
*note, the doublestreet-trigger doen't have to hit in sequence, you track the 3 DS within H/L separately. As soon as 1 DS within H/L has hit 2 times (without the other 2 being hit) that's a trigger....(if that wasn't understood already) :S
