Open clusters are host the several identical stars in the similar physical and chemical environment. They become interesting objects to identify the variable stars in the lower metallicity domain. In the present paper, the CCD time series observations of cluster NGC 1960 and DOLIDZE 14 are performed to search the variable stars within them. A comprehensive study of differential phototometry and secondary standardization transformation is carried out to search the stellar pulsation. A total of 18 and 4 short periodic variables found in the field of NGC 1960 and DOLIDZE 14 respectively. Fast Fourier transformation techniques are utilized to compute the pulsation. Author also discovered an exo-planet aorund ID 900 of NGC1960 with periodicity about 99 days.
