ForexTradingManual

In the stock market, this rule applies to the nth degree, as
you are investing your own money in what could be
considered a high risk wager, and you are playing with fire if
you do not have at least a general background knowledge of
how it functions. Since having a background in any area is
helpful in guiding you down a path in that particular region,
the more solid your basis of investment knowledge is, the
more likely you are to profit from any attempt to trade on
the open market.
