Detailed Explanation:

While 50% is not a ratio derived directly from the Fibonacci sequence (1, 1, 2, 3, 5...), it is universally included in Fibonacci Retracement tools and analysis (Dow's 50% retracement principle) and is accepted as a key "Fibo" level in technical examinations.

Detailed Explanation:

(Note regarding answer key logic): The Parabolic SAR uses an Acceleration Factor (AF) that increases as the trade progresses. Mathematically, increasing the acceleration makes the indicator "faster" or more sensitive, which is equivalent to decreasing the number of days in a moving average calculation. The answer key identifies C as the correct description42.

Detailed Explanation:

For horizontal counts (measuring the width of a base), the formula is typically the breakdown/low price plus the width of the formation. Specifically: Base Price + (Number of Columns in Base × Box Size × Reversal Size). Option D approximates this structure most closely9.

Detailed Explanation:

A Belt-Hold is a single candlestick pattern (Opening Bozu). A long belt-hold line (indicating a strong, sustained move from the open) is more significant than a short one. Therefore, statement B is incorrect.

Detailed Explanation:

"Umbrella" lines are candlesticks with small real bodies and long lower shadows (like Hammers and Hanging Men). Their interpretation depends on the prior trend. If they appear after a downtrend (Hammer), they are bullish reversals. If they appear after an uptrend (Hanging Man), they are bearish reversals. Thus, they can be either.

Detailed Explanation:

When a reversal pattern completes, it indicates the previous trend has ended. Therefore, the maximum implication (objective) is that the price can retrace 100% of the prior trend. While specific targets are calculated using pattern height, the theoretical limit of a full trend reversal is the start of that trend.

Detailed Explanation:

Broadening Formations (expanding triangles) represent a market that is out of control, with buyers and sellers becoming increasingly emotional and irrational. This high-volatility behavior is characteristic of the confusion seen at major market tops.

Consolidation represents a pause in the trend. Prices typically move sideways within a defined range (rectangle/flag) and volume typically contracts (is low) as traders wait for the next59 directional cue.6061

Detailed Explanation:

Oscillators like the Relative Strength Index (RSI) and Moving Average Convergence Divergence (MACD) are excellent tools for filtering. For example, a bullish hammer candle is more reliable if it occurs when the RSI is oversold or showing bullish divergence.

Detailed Explanation:

A Doji is formed when the opening price and the closing price are virtually identical. This indicates that neither the bulls (demand) nor the bears (supply) were able to gain control by the end of the session, signaling that supply and demand are in balance (indecision).
