What amount of stamp duty should I affix on the transfer deed?

For Shares, stamp duty @ 0.25% of the market value or the consideration amount (whichever is higher) should be affixed on the transfer deed. The rate per share can be picked up from any newspaper. The date for which the rate is picked up must be the same as the execution date mentioned on the transfer deed.

Special note:

With effect from 1.7.02, for transactions in physical form, the Government of Maharashtra has banned the sale and use of share transfer stamps. The Government has started putting their stamp by using franking machine at the Stamp Office. For transactions executed in Maharashtra, instead of affixing share transfer Stamps, stamp duty @ 0.25% of the market value or the consideration amount (whichever is higher) should be franked on the transfer deed.

Electronic transactions do not attract any stamp duty, however each Depository Participant may levy a transaction charge. The rate should be confirmed with your depository participant beforehand.
