I have checked my mailbox and found that some of the newsletters are suitable for trading. These are:
GCI Financials - not too useful but at least gives some info.
GFX Group and Forex.cf
I don't really pay attention to the analyses usually. My argument is simply. The puprose of these newsletters is marketing and not my financial profit. However, these letters quite often bring my attention to facts that are interesting. Like I don't trade USD/CAD usually but one of these newsletters brought my attention to CAD. I have checked into it and it was nearly a perfect trade.
