Transfer it to our pool account (see: http://help.rksv.in/solution/categories/28100/folders/48252/articles/25726-what-is-the-time-taken-to-transfer-shares-from-another-demat-account-to-your-pool-account-) when you are ready to sell and it will show up in your trading terminal under your account. Then you can go ahead and sell it for zero brokerage
