Math Problem Statement
Write it down exactly
What does the Doji(v_i) formula represent, and how is it applied?
Solution
Here is the exact formula written down from the image:
\begin{cases} 1, & \text{if } \left( \frac{|\Delta v_i|}{H_i - L_i} < 0.1 \right) \text{ and } \left( \frac{H_i - \max v_i}{3 \cdot |\Delta v_i|} > 1 \right) \text{ and } \left( \frac{\min v_i - L_i}{3 \cdot |\Delta v_i|} > 1 \right) \\ 0, & \text{otherwise} \end{cases}$$ Let me know if you want further details or have any questions! Here are 5 questions related to the formula: 1. What does the parameter $$v_i$$ represent in this context? 2. How is the difference $$\Delta v_i$$ calculated in the formula? 3. What are $$H_i$$ and $$L_i$$, and how do they relate to the variables in financial terms? 4. Why is the threshold of 0.1 used in the first condition of the inequality? 5. What role do the max and min values of $$v_i$$ play in the second and third conditions? **Tip:** In financial contexts, the Doji candlestick often represents market indecision, where the open and close prices are very close to each other. This mathematical condition could be attempting to formalize such patterns.Ask a new question for Free

Doji(v_i) = 1, if (|Δv_i| / (H_i - L_i) < 0.1) and ((H_i - max(v_i)) / (3 * |Δv_i|) > 1) and ((min(v_i) - L_i) / (3 * |Δv_i|) > 1), otherwise 0
