http://en.wikipedia.org/wiki/Relative_Strength_IndexAs you can see from the chart, the RSI ranges from 0 to 100. An asset is deemed to be overbought once the RSI approaches the 70 level, meaning that it may be getting overvalued and is a good candidate for a pullback. Likewise, if the RSI approaches 30, it is an indication that the asset may be getting oversold and therefore likely to become undervalued.

why ? Because a longer term indicator told them it was still a good price.
