Query on Bank Balance vs Demat Funds for Schengen Visa

I am planning to apply for a Schengen visa. The majority of my funds are held in my demat (stock) account, and I typically do not maintain a high balance in my savings account. Would it be advisable to transfer funds to my savings account and maintain them there for 2–3 months before applying, or would it be acceptable to apply immediately while providing proof that the funds were transferred from my demat account? The application will be for five adults and two children
