My opinion on flat betting. When I started playing in 2020 I used a negative progression. I did win and I did lose sessions. When I lost I went deep in a hole. I accepted that, and when I won, I still had a stop limit. Like the stop loss. I did keep accurate records on my play. After 6 months of play I was down for the year. I didn't like going into a big hole when I lost. It bothered me that I had to win a lot to make up for that loss. In 2021 I decided to try flat betting following @kachatz1 advice. I like NOT going deep in a hole when I lose my first few bets and I still have a stop win of 3 units with the exception of still playing if I am on a run or a chop (zig zag). This year isn't over yet but I am up and I am up 62 units, and that includes a bad losing streak a few months ago. I am a broken record I say it all the time......Keep accurate records of your play! Start at $10 units, as you get better than up your unit size as your records prove that you can win flat betting. I started at $10 units, then went to $25 units and now I am at $50 units. I feel comfortable because I know if I lose my first 3 bets the most I can lose in any given session is $150. I have played side by side with @kachatz1 and he has seen my earlier play at $25 units and the last time we were together I was betting $50 units. At some point I will feel comfortable to play $100 units with an ultimate goal of playing $500 units in the future. At $500 units all I would need is to be up 1 unit to make $500. Now think about this, go back and check your score sheets, have you ever been up 1 or 2 units, but lost the session? Well if you played bigger units, (doesn't have to be $500 units) once you get to a +1 or +2 win,you stop playing, that takes discipline. It's hard to stop playing when you are winning, but I do it and I am up 62 units for the year flat betting, and I didn't start playing until I was vaccinated which was the middle of April. You might think 62 units is not a lot of units, but If I was betting $500 units? You do the math. Keep accurate records and flat betting is the way to go.
