Detailed Explanation:

This refers to the Theory of Contrary Opinion. When the consensus of experts and media becomes universally bearish, it usually indicates that all negative news is discounted and potential sellers have already sold. This extreme pessimism often occurs right before the market bottoms out and reverses upward.

Detailed Explanation:

P & F charts are unique because they ignore time. A new 'X' or 'O' is plotted only if the price changes by a specific box size. If the price does not move enough, the chart does not update, unlike a bar chart which adds a new bar every time period regardless of price movement.

Detailed Explanation:

Volume confirms the trend. A rally on rising volume usually confirms the existing trend or a breakout, rather than a reversal of a major trend (unless it's a climax). However, statement B suggests a rally on rising volume points to a reversal. In the context of a downtrend, a high-volume rally could be a reversal, but generally, rising volume validates the move.

Correction based on source key: The source key marks B as the answer ("Not true"). The logic is likely that a rally on rising volume is normal bullish behavior, not necessarily a "reversal" signal (unless coming off a bottom). A rally on declining volume is the reversal warning.

Detailed Explanation:

In Elliott Wave Theory, the Guideline of Alternation states that the market does not repeat the same type of corrective pattern consecutively. If Wave 2 is sharp and simple, expect a difference in Wave 4 (likely sideways and complex)35.

Detailed Explanation:

A Harami consists of a large mother candle followed by a small real body (baby) that is contained within the first. This small real body is often a Spinning Top (or Doji), representing a sudden loss of momentum.

Detailed Explanation:

Detrending removes the long-term trend component from the data to isolate the cyclical or short-term fluctuations. Once the trend is removed, the resulting series oscillates around a mean (zero line), appearing range bound or stationary.

Detailed Explanation:

Seasonal: 1 year.

Presidential: 4 years.

Kondratieff: ~54 years (Long wave).

Therefore, the order Seasonal, Presidential, Kondratieff is correct40.

Detailed Explanation:

The Harami consists of a large body followed by a smaller body contained within the first. This describes the exact same price action as a Western Inside Day (where the High and Low are within the previous day's range).

Detailed Explanation:

The core concept of Elliott Wave is its fractal nature. Any wave can be subdivided into shorter waves (e.g., Wave 1 has 5 sub-waves) or expanded to be part of a larger degree wave. This self-similarity across timeframes is fundamental37.

Detailed Explanation:

Resistance is defined as a price level above the current market price where selling interest is strong enough to overcome buying pressure, causing the price advance to halt or reverse. Option A describes support.89
