At a 90% winners avg, you would have to risk 3x+ what you stand to gain per trade. That's a fact in real trading. No ands, ifs or buts about it. The stats are not showing this to be the case. So it's all insta-bogus, don't waste your time.
Save your money and trade the NQ, YM or RTY futures. You should be craving high volatility in order to stand the greatest chance of success in the long-term. Currency trading is a total krap market compared to the e-minis [Notice I left out the ES...too choppy by comparison to the other three].
You may want to reconsider. Are you aware of the daily total turnover at Nasdaq? Around 160 billion USD. Currency markets turn over around 6 trillion USD per day. Currency trading is about the cheapest way to participate in financial markets, bar none. Who else charges you 0.2 basis points average commission with an additional 0.1-0.2 basis point bid-ask spread? Any stock on Nasdaq or NYSE trades at significantly higher transaction costs, with many additional regulatory hurdles in order to short-sell, for example. I obviously recommend trading with a reputable broker such as IB. Nowhere else can an investor get in and out at such low cost. So, I am not sure what you mean with krap market? Crap brokers perhaps?
The banks defacto set currency rates. Forex really isn't a good market. The currency futures are liquid (perhaps not as liquid as forex) without exposure to bank fraudsters that appear to pop up every 3-5 years.
If this were so then there would be plenty arbitrage opportunities between futures and spot.
Are you implying there's no carry trades? There certainly are. They may not be available to forex pikers but the big boys in the banks are running carry trades all the time.
