Doragio,
If we are talking about common investors or traders
IMHO
Fx market is considered the most difficult tradable market for:
- 24 hours non-stop market which is impossible to be followed by normal trader. divided into 3 sessions each one has its commander who has its own visions and policies.
- Unavailabilty of total market volume or flow studies like other markets.
- Unavailbility of ONE governing authority.
- largest daily turnover attarct enormus big dogs who usually play on the account of small investors.
This is MHO, others may have other reasons.
