Here is the daily chart of Gold that I refer to in the second post. Now we have an uptrend, so buying the dips is the prudent play.
Percent R is a stock choice for most software packages. If you have it just wait for a reading of 10 or less, and buy the market once it gets to that reading. Use a trailing stop of whatever your risk tolerance allows. It should be itleast $10 due to the volatility of this market, and probably much more.
If you do not have that indicator, all it represents is the close compared to where it is within the range from high to low of the last 10 days. A 10 reading tells you that you are in the lowest 10% of the last 10 days range, hence oversold.
