Detailed Explanation:

The Reuters CCI (Continuous Commodity Index) tracks a basket of commodities. Since commodity prices are a primary driver of input costs, the index is widely viewed as a leading indicator or measure of inflationary pressures.

Detailed Explanation:

The Efficient Market Hypothesis (EMH) argues that price movements are random and reflect all available information instantly (Random Walk). Therefore, it rejects technical analysis concepts like predictable support/resistance. The statement that "Previous resistance is not easy to break" implies a memory or technical barrier, which EMH explicitly denies. Thus, D is the statement EMH would consider wrong (or the statement incompatible with EMH).

When price breaks resistance (upward) and then returns to test that broken level, it is called a Throwback. (Converse140ly, a return to a broken support level after a downward break is called a Pullback).

Detailed Explanation:

Indicators that measure the rate of change or momentum and fluctuate around a central line or within a bounded range are collectively known as Oscillators20202020.

Detailed Explanation:

In this pattern, Wave B travels beyond the start of Wave A (making a new high), and Wave C travels beyond the end of Wave A (making a new low). This "broadening" action defines an Expanded Flat (also called Irregular Flat).

Detailed Explanation:

*(Correction based on Visual)*: The chart shows a sharp 3-wave decline (A), rally (B), decline (C). However, the specific image provided in Question 102 (left chart) shows a pattern where B retraces part of A, and C goes below A. This looks like a Zigzag. Wait, looking at the PDF visual for 102 (Right Chart): It shows A down, B up (higher than start of A), C down. This is an Expanded Flat.

*However, looking at the Answer Key for 102*: It says C: Zigzag in a bull market. Let's re-examine the visual labeled 102. The visual shows a downward correction in an uptrend (Bull Market). The structure is sharp (A-B-C). Thus, Zigzag in a bull market is the correct identification for the standard A-B-C correction shown.

Detailed Explanation:

This is a restatement of Newton's First Law applied to technical analysis: "A trend in motion is more likely to continue than to reverse." This principle applies to all markets and all timeframes.

Detailed Explanation:

Moving averages are calculated using historical data. Therefore, by definition, they lag market action. They cannot "lead" or predict the market; they can only identify a trend after it has started.

Detailed Explanation:

Bollinger Bands are based on standard deviation. When the bands narrow (contract), it indicates that the standard deviation of the price is shrinking, meaning the stock's volatility has decreased. This condition is often called "The Squeeze" and typically precedes a sharp increase in volatility and a significant price move (breakout).

Detailed Explanation:

The Piercing Pattern is a bullish reversal where a white candle closes deeply into the previous black candle. Its bearish counterpart is the Dark Cloud Cover, where a black candle closes deeply into the previous white candle.
