There's a lot of ignorance in this thread. But ignorant traders are good for the market... and I'd encourage Paris to join a number of these and bring her cash to the markets and help people who way.
If you are learning how to trade well then you may benefit from studying a book called Improving Trader Performance - recognized egies from the very edge of trading plogy. Its all about learning when the problems occur 13, and relearning.
As always, good luck; a few of you may require an awful lot of it to avoid the 95% (possibly 19 from 20?)
