In this article, we introduce another new subclass by using $q$-analogue of the Noor operator and based on it we investigate a subclass with fixed finitely many coefficients for the univalent holomorphic functions. We obtain a number of useful properties such as coefficient estimates, extreme points, convexity and convolution-preserving properties.
