Sorry, I totally missed it!  Here are my thoughts:



The financial world is full of snakes and snake-oil salesmen.  The retail Forex market, even more so.  The vast majority of currency traders consistently lose money:

I have periodically glanced at this report ever since the NFA required retail foreign exchange brokers to publish their profitability figures and it has been a fairly consistent trend: 80% of all traders lose money every single quarter.  For this reason, you are wise to realize that the vast majority of signal providers/Forex spam emails are absolute lies.

My suggestion is to spend your time learning about the principles of trading rather than focusing exclusively on the Forex markets.  After all, if you learn to manage risk and identify good trading opportunities, you can transfer these skills to any market/risk-based endeavor you enter.  On that note, here is a list of resources I've found to be helpful.




Now, as to this question:


In general, hourly moving average crossover systems are not profitable outside of BTC.  The extreme volatility and relative infancy of the market allows aggressive trend following methods to profit.  

Here's a backtest of the 10/21 crossover on EUR/USD hourly since the beginning of the year.





Daily crossovers are still profitable, however.  But you must be willing and able to stomach periods drawdown.  For example, if you traded the 10/21 crossover, you would not have earned a profit between 2004 and 2006.
