The first Stock SIP order will be executed on the day you set it up.
All subsequent orders will be executed at 11 AM, according to the frequency and day you selected.
Why 11 AM?
When markets open, the first few hours can often be volatile. To protect you from this volatility and provide a smoother investing experience, all Stock SIP orders are executed at 11 AM.
