Statistical Principles (Click to expand)
This chart uses the "Sliding Window Statistical Method", which calculates the occurrence frequency of each number by moving backward through recent draw periods.
For example, if the sliding window width is set to 50 draws and 50 reference points are generated:
The system will sequentially count the number of times each ball appears within ranges such as “Draws 100–50,” “Draws 99–49,” … up to “Draws 51–1,” producing a total of 50 reference points.
Each reference point represents the frequency of appearance within that window, and the curve connects these points chronologically from left to right to form the trend line.
- Horizontal axis: Draw periods (Old → New)
- Vertical axis: Number of appearances
- Rising curve → Recently drawn more often (Hot numbers)
- Falling curve → Recently drawn less often (Cold numbers)
- Green dashed line → Average value
