Delivery trading

Do you allow buy today and sell tomorrow in zerodha. Or what is the minum no of days a stocks should be held before selling.,
Do you allow margin trading on held stocks.
Thanks.

Yes, you can do BTST trades in Zerodha but before you do I would suggest you go through this post to understand more about the risk of BTST trades.
There is no maximum time period for holding a stock, you can hold it as long as you wish assuming that the company remains solvent.

Currently you will not get margin for BTST/Delivery trades in Zerodha. But as per @nithin they are working on this regard.

very helpful… thank you… best regards
