Bankroll fluctuation and influence factors.

Now, let’s see how many management do work in practice. So we will discuss a subject as fluctuation (also called dispersion).
Fluctuation: it’s a short timed count change (take off or fall down), which are different compared to average results. The size of the fluctuation depends on some important factors:
- Your win rate (win rate: is the profitability indicator of your game, on distance, and is equal to the number of big blinds won in 100 deliveries), is the basic factor that influences on the fluctuations quantity of your bank roll. A solid plus player with a win rate of 2BB/100 will receive a down streak (minus) of 300BB probably once in 10 years. A less experienced player with a win rate of 0, 5BB/100 will be in a losing situation 300BB every year or once every two years. The conclusion is simple: the higher your win rate is the less negative short timed inclination of the bank roll you have. That is why studying the theory of poker and improving your game can help to decrease the fluctuation of the bank roll.
- Your psychological stability can influence on the bank roll fluctuation range. If you are emotionally unstable, losing 50BB can become into a 200BB down streak or even worse. When the player falls into the tilt position and can’t stop, he risks to lose it all, emptying his bankroll.
- Your game style influences the gaming account fluctuation range in a lower way than the mentioned factors. The player, by playing in a losing way, but possessing an equal to a tithe player win rate, will have more fluctuations overall. But that doesn’t mean that the positive losing-aggressive player has to change its game style, he just has to have a bigger bankroll to resist the swings.
- Your opponent`s game style, doubtlessly, influences some way on the fluctuation of your bankroll. The more you play with losing opponents, the bigger gets your account’s fluctuation range, but that is offset by the growth of your win rate.
- When playing in MTT tournaments, huge influence, on the bankroll’s fluctuation range, have the payments structure and the tournament participant’s number. The bigger the game field size is, the less you will occupy one of the winning positions, where the players receive money. In the table you can find the numbers, counted to almost 200 tournament’s participants. In tournaments with a high number of participants, but a small commission, your dispersion will be high, but the ROI will also be high, because you’ll easily defeat the weak players. Also have in mind that in tournament games with rebuys you’ll need a higher bankroll, than in a free out tournament.
- The number of players at the tables in cash games has the inverse relation your game’s dispersion. In large tables the fluctuation will be higher, in short, lower. This happens because in short tables the game is more losing-aggressive. Heads-up and sit-and-go tournaments offer a high bankroll fluctuation range. In games to just one win rate have a big influence on your dispersion. The player who only wins a 55% of the games will have really big swings; meanwhile a stronger player with a 70% win rate can avoid it by doubling the bankroll size from the one shown on the table.

After reviewing the materials about the possible account fluctuation you will be able to define in a more exact way, the size of the needed bankroll having in mind the individual characteristics of the game.
