Sell-signal since reaching the (grey) horizontal-resistance at approx. 80.50 - buy-signal when rising above it, or in case of a correction to the (green) support. 29.10.2010 - 77.04
The longer-term chart since 1998 shows that the correction (since reaching the black resistance) just arrived at the (green) support providing a hold - thus, a buy-signal is active at the moment. Next sell-signal hereafter when reaching the (grey) horizontal-resistance at approx. 80 (buy-signal when rising above it), or when breaching the (green) support currently at approx. 76. 
Sell-signal still active, especially as the (red & green) supports did not hold, whereas a first buy-signal was issued with arriving & holding at the lower (green) upward-trend-channel being changed to a sell-signal with subsequently reaching the (green & red) resistance at approx. 78. Next buy-signal when rising above the (green & red) resistance, or in case of another correction to the (green) support at approx. 76.

23.07.2010 - 82.46

25.06.2010 - 85.28
The close-up since 2008 shows that a correction started since reaching the (green) upward-trend-channel at approx. 88.5 in May 2010 & that lately, the (lightblue) support was breached (buy-signal when rising above this trendline currently at approx. 86).
Indicators:
RSI: sell-signal since breaching the (green) support - buy-signal when rising above it.
ATR: the volatility decreases since reaching the (grey) resistance - a strong increase is expected when rising above the (grey) resistance.
ROC: sell-signal since breaching the (red-green) triangle-apex recently - buy-signal when rising above it.
MACD: sell-signal still active, whereas at the the currently reached (green) support a sideways-consolidation can start & lead into rising curves (buy-signal).
AROON: see below.
The close-up since 1998 shows that since the price trades below the (black) trendline, various attempts were made to break this resistance - however, not successfully. After the (blue) triangle-apex was reached, the thrust began. Lately, the (black) resistance at approx. 89 was not broken & a sell-signal was issued. Buy-signal when rising above it, or in case of a correction that does not breach the 75 price-level (triangle-apex), whereas at the (grey) horizontal-support (approx. 80) the next important support lies (buy-signal when arriving & holding on it - sell-signal when breaching it).
Indicators:
RSI: sell-signal since breaching the (grey) support - buy-signal when rising above it.
ATR: the volatility decreases since reaching the (grey) resistance - a strong increase is anticipated when rising above the (grey) resistance.
ROC: sell-signal since breaching the (green) support - buy-signal when rising above it.
MACD: see above.
AROON: see below.
Since about 1988, the price is dominated by the (blue) triangle, whereas a breakout above the upper (blue) leg at approx. 92 was accomplished in 1997. Despite a successfull pullback to the (blue) leg at 90, numerous further pullbacks occured since reaching the parallel (blue) resistance at 105 resp. 120. In early 2010, the apex of the triangle was touched, whereafter a rise to the (blue) resistance at approx. 88 points followed. Since the current price of 85 trades below this resistance, a sell-signal predominates at the moment - until rising above it (buy-signal). In case of a further correction, an important support-zone (black horizontal-support) lies at approx. 80 & as well 72. Since the price started to rise after reaching the triangle-apex the expectation is a thrust to the upside since then & only changes into an equivalent sell-signal when breaching the price-level of the apex as a thrust to the downside is then expected. The ongoing thrust to the upside is expected to gain dynamic when rising above the (blue) resistance at approx. 88 points. The goal of the thrust is to rise above the high of the breakout (120) & to transform it into a new support for a new upward-trend thereafter.
Indicators:
RSI: buy-signal since arrival & holding above the (red) support - sell-signal when breaching it.
ATR: after the strong increase in volatility in early 2008, a pullback to the (green & red) support occured. Since then, the price is thrusting to the upside (i.e. the volatility rises strongly) with the goal of not only breaking the (grey) resistance at 1.25, but as well the high of breakout at approx. 1.50 from the year 2008.
ROC: lately, a correction to the (green) support took place (incl. a slight breaching) - hence, the prevailing buy-signal turns into a sell-signal when breaching it again.
MACD: see above.
AROON: with currently -40 points within the neutral- to buy-range.
