It's only a " loser way to trade" if you don't know what you're doing. I have made of living from weather trading since the 80's sir. And so have many, many others. For those who are here to learn, dismiss this guy's advice. Find yourself a reliable weather source and you'll pave your path down Easystreet if you learn how to do it right. But weather trading is far above Coral's head I'm sure. If you don't understand something, pee all over it.
If you wait for just the charts to show the way, you'll be a tired old grey man like him sooner than you think.
