Whats a downswing/Upswing???

[kiddo]

Lately there been much discussion about loosing streaks. What is normal? How big can they get?

But I am not sure I understand the concept.

I understand it as follows:

At any certain point you got a bankroll of X dollars. A loosing streak is the biggest gap between this X and your bankroll. For example: 1 january 2003 I got $1500, 1 february 2003 I got $500, 15 february I got $900, 1 march I got $300 and 1 april I got $3000. Then I can say my biggest downswing so far is $1200.

This is if I am normally winning at this level and that means: A winning player can only have downswing (the upswing is forever...) A losing player can only have upswings (he is losing forever...)

Is this the right way to look at up and downswings?
