Do you adjust your budget? why? it is after a big win or a big lose?
Yes, I adjust my gambling budget, and it's proportionate to my wins and losses. Although it's not directly proportionate to avoid overdoing it, and a lack of withdrawal through excessive compounding of the profits. However, this is not what I do all the time, as I could hold my budget plan for as long as possible to avoid the greed and higher risk of wagering more just because I gained more.
If you are proportionate in gambling, you are a lucky gambler. Most gamblers do not win even-handedly and most lose. Budgeting strategies should be vary person to person that's true but I haven't tried that the same way you have. I set a fixed budget limit at the beginning of the week. If I lose that amount of money I don't add a new budget. If there is a some amount of winnings during the week, I withdraw it and keep myself in control after winning to prevent being overly greedy. By controlling yourself in gambling you can balance your winnings with your losses and adjust your budget accordingly.
