For traders—especially those with limited funds—day trading or swing trading in small amounts is easier in the forex market than other markets. For those with longer-term horizons and larger funds, long-term fundamentals-based trading or a carry trade can be profitable. A focus on understanding the macroeconomic fundamentals driving currency values and experience with technical analysis will help new forex traders to become more profitable.

The blender company could have reduced this risk by shorting the euro and buying the USD when they were at parity. That way, if the dollar rose in value, the profits from the trade would offset the reduced profit from the sale of blenders. If the USD fell in value, the more favorable exchange rate will increase the profit from the sale of blenders, which offsets the losses in the trade.
So far, so good. I saw good consistent gains the first 2 months I used it. Remarkably consistent actually. About 4-6% per week for about 9 weeks in a row. Which was encouraging. Then, however, I got a bit cocky and went in way too big on a long NZD/USD trade about 2 months ago, and I've been fighting my way out of it ever since. But that was really my own fault. There's no reason I should have ended up in a position where I had a loss so big I couldn't manage my way out, if I had been following the rules.
