When we should increase our unit size?
I was using the classical method, (increasing your unit size when you increased your bankroll by %20 or 30) but over last 6 month, I'm using a different method and very happy so far.
Let's say your starting bankroll is 1,000 and you're risking %5 per game. So you risk 50$ per game. You increased your bankroll to 1300, increased your bet size to 65.
But you were on a great run and a cold run happened after you hit 1300. So when you go 0-3, you will lose 195 (65x3) instead of 150. (50x3)
So, when I increase my unit size right now?
I increased my bankroll by %25-30? Well, I wait for a cold streak. Let's say our bank is 2k, I'm betting 100$ per game (%5). I went 1-0, 2-0, 2-1, 3-1 and increased my bank to 2600. It was a good streak and you know good runs won't go forever. So I don't increase my bet size yet, waiting for a cold streak. So I'm still betting 100$. (not 130$)
Then I went 0-2, 1-2.
Now, it's time to increase your unit size! I went 1-4 and lost only 300$ (assuming odds are +EVEN, damage will be -309$ if odds are -110. You win 91, You Lost -400.) If I was betting 130$, then damage would be 420$! My bank is down to 2300 and i'm increasing my unit size to 115$.
It's not a chase system. You just try to have law of averages by your side.
