OK, so what do we got? Progression is the key to the grail, according to those who have found it. I have tried +1/-1 progression, but that failed because when you get into a hole, it requires SEVERAL hits to recover and reach a new high. And in most cases that will not work, only bring you down into a deeper hole than before.
What we need is a progression that survive many losses, and STILL recover quickly. And this is exactly what this progression, my invention does. it's a single dozen progression. A dozen cycle is 3 spins, so THIS progression increase bets (double bets) after 2 losses in a row. it never decrease bets, just double for each 2 losses in a row, and reset progression to 1u when reach a new high. Simple as that. playing with this progression you recover and reach a new high in most cases after 1-3 hits.
What bankroll is needed? This i haven't figured out yet, but i guess a 500u bankroll playing with 1u bets should be enough, (?)...
First tests was played with 1u bets, (wingoal +100u, stoploss -500u)
