πŸ”Ή 1. CPR Levels (Central Pivot Range)


Let's calculate CPR using your daily levels:

(CPR helps identify the intraday support/resistance zones.)


Formula:


Pivot (P) = (High + Low + Close) / 3


BC (Bottom Central) = (High + Low) / 2


TC (Top Central) = (Pivot × 2) − BC



Calculated Values:


P = (57262.85 + 56780.15 + 56828.80) / 3 = 56957.27


BC = (57262.85 + 56780.15) / 2 = 57021.50


TC = (56957.27 × 2) − 57021.50 = 56893.04



πŸ“Œ CPR Range:


Top Central (TC): 56893


Pivot (P): 56957


Bottom Central (BC): 57021



> CPR is narrow, suggesting a potential trending day. Price closed below CPR, indicating bearish bias.
