πΉ 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
π 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.
