This is a great question, and I am glad somebody asked it. But I think the real question is how many losses before we can say we are done?
I am at a loss now of 10k PHP ($180-200). (estimated only) But I have not stopped yet. I am still playing, although it's not continuous, so I guess that's why it takes so slow. Also, I am playing slots with just a 1 peso bet. The minimum of most slot games in the local online casino.
I think my point of no return is when I lost 20k in slots only, and it won't give me back a part of what I lost. I mean, I am expecting at least a bit of RTP, but if that doesn't happen until I feel like I am losing much, then I am gone.
Good for you, you've figured out what to do. The important thing in this case is to understand when to stop, given that the loss has become too high.
Without wanting to you used a budget system, you said after 20k i decide not to lose anymore and i stop
Try to set a monthly budget and you're good to go.
