I am a Master's student in Ireland studying the profitability of TA in the foreign currency markets for my thesis. I would be most grateful if I could ask your advise and pick your brains on a few issues that I am encountering. I apologise in advance for my ignorance in this area!

Perhaps the biggest problem facing me is which trading rules to study. At the moment I am considering using the RSI rule, and the Filter rule....but if there are different trading rules that are more relevant and used more frequently then please let me know.

Also, regarding trading time, would it be more common to have trades from an account continuously (moving to different markets as they open), or would trading only take place during the trading hours in one country?

Finally, how often (on average) would trades be conducted (every few minutes, one an hour etc.).

I realise this is alot to ask, but any help would be greatly appreciated.
