Analysis : Since you ketu is placed in second house of birth chart which is house of saving and lord of this house is Venus. This is major problem that your planets which are placed in good houses are not giving results. Moreover, in your fifth house Sun is placed with Mercury and Venus. Mercury - Sun conjunction makes Budh Aditya yoga, but degrees of Sun and Mercury are very week , that is the reason this is not effective. Also note that your current antardasha is of Ketu which is a problematic period for your savings and finances.

Following are some remedies you have to do to reduce the effect of Ketu placement in second house :
1. Chant this ketu mantra : Aum Sran Srin Sron seh Ketve Namah ॐ स्रां स्रीं स्रौं सः केतवे नमः॥
This mantra should be chanted for 17000 times within 40 days

2. Do fasting of Mondays and visit Shiv Mandir on outskirts of city and not near to your house.
3. Chant "Om Namah Shivay" mantra 108 times daily.
4. Feed milk to Dogs on Saturdays .
5. Do medidation on daily basis for at least thirty minutes to reduce the negative energy of Ketu.
6. Visit Bhairo Mandir on Saturdays.
