I am using above formulas shown in picture to extract data from column "C". I could extract data of "CE" but where I am making mistake to extract data of "PE". Everything is shown in picture. Could anyone help me out.
One more thing to add here. "CE" and "PE" rows are dynamic. In daily data strike price could add or subtracts. Means adding of strike say 5600, 5700 could possible on both side.
