Sure. For me the threshold is the money I have deposited in my casino account. I have a rule of never adding to the balance during a session. If I lose it all it means the and for that day, maybe for longer, depending on how long it was since the last time I sent money to a casino.

Sometimes I played on a casino account with the money they gave me for free or money I got from a signature campaign. If that went to 0 I'd stop until the next paycheck.
