Quote from rcanfiel:
More often then not, they are used to demonstrate how to allow one to retire in a year from trading a $5,000 account.
At best, they give you an optimal reinvestment path. But a lot of bad things happen on the yellow brick road. If you ignore the Risk of Ruin and the other wicked witches, then you might find Oz...
Understanding the Risk of Ruin is, of course, paramount in trading. You "gotta leave enough to trade another day" as they say.
