This is an EC strategy. (Need more testings).
Trigger: Wait for RBR or a BRB. When that happens you bet for this trend to END for the next 3 spins. STOP after 3 spins (if not hit) and wait for the new trigger.
For an example; RBR--> Now you bet RED, RBRB--> Now you bet BLACK...and so on.
Progression: A 3 level Marty.
Level1: 1-2-4
Level2: 2-4-8
Level3: 4-8-16
Level4: 8-16-32
...and so on
When one level is lost you go to the next level (for the next trigger) and stay on that level until recovered. THEN go back to level 1.
