What are you selling?
I agree with your post, I traded cash fx for over 10 years now, close to 600mln usd notional equivalent per month. The only reason I see why fx got such bad press is because it's unregulated and hence there are tons of shady brokers out there. Successful fx traders for me are the absolute top predators in animal kingdom. No other asset class requires being so on top of events, economic data releases, news... It requires a keen understanding of macro economic theory, interest rates and fixed income markets and commodity markets in general, up to date knowledge of other large market participants, knowledge of soft exotics that do at times impact cash fx
Sometimes one must be around the desk for 12-16 hours and even get up at night. Show me some stock punters that need to put in this much effort. To me it's one of the most complex asset classes because quite a number of additional variables impact currencies. The reason so many who attempted to make money in fx fail is because they think following a little price action is all there is to it.
But cash fx in my book is also the most rewarding because the risk of insider trading and manipulation is absolutely minimal, it trades round the clock with mostly deep liquidity, hence one can get in and out at an instance. Add to that the tightest avg spreads of any asset class and you have an incredible instrument that really puts the reason for failure squarely into the camp of the trader.
