@Dhanvan manas In Bharti Hexacom, I was assuming that Groww wasn't allowing the user to place pre open order. But, after 9.45, it was allowed. However, those who deals in grey has to place order b4 9.43, and in this, Groww has worst facility.
BSE SME IPO restrictions and Pre open restrictions are worst facility by grow and surprisingly they are not changing anything even after multiple complaint. Customer care Wale dhadam se sorry bol de te he... Abhi nahi develop Kiya... !!
