Recently I have been playing at the .25/.50 stakes NL tables, both on party where the buy-in is $25 and elsewhere where the buy-in is $50. My experience has been that the swings can be really huge. One day, I had won $120 when playing at noon, and before midnight that evening I had lost $90 of it. And yesterday, I had a nice upswing where I won almost $150, just to lose almost as much today. None of these ups and downs seemed to me as very special, it was not like I was having incredible luck when I was up and there were no terrible 5 bad beats in a row or exceptionally bad playing by me when I was diving. This made me think about bankroll management. If you have 20 buy-ins at party, that's $500, which I believe most of you would consider a reasonable bankroll size for a winning player to play those tables. But if you can easily swing down one fifth of your bankroll just in one day - is $500 really enough? Is it just me risking too much of my bankroll on a single occasion? That would mean no multi-tabling, and I'm bonus whoring, so not multi-tabling or going down to lower stakes is not an attractive option for me right now.

Give me some input.
