Yes, Marwadionline will take care of any issues that arise with the exchanges on its customers behalf e.g. short deliveries, bad deliveries etc
There are two type of settlements. One is weekly settlement (EQ) and the other is rolling settlement (BE).Weekly settlement starts on Wednesday and ends on Tuesday.Rolling settlement transactions are squared on daily basis.
No you can choose to sell the share before the end of settlement cycle. However once the settlement cycle is over you have to take delivery by paying for it.
The shares will come into your demat account once the settlement takes place. Hence generally you can expect the shares to come into your Demat account every Thursday following the end of NSE settlement cycle. In case you do not receive the shares, it may be due to the stock being in 'No Delivery' period . In this case the shares will come from the exchange after the 'No Delivery' period is over which could be 2-3 weeks away. Alternatively, it is possible that the shares may not have come from the exchange because of shortage. In this case, the exchange conducts an auction and the shares may be received a few days later.
An auction is a mechanism utilised by the exchange to fulfil its obligation towards the buying trading members. Thus, in case for a settlement, the selling trading members have delivered short, their deliveries are bad or they have not rectified the company objection reported against them, the exchange purchases the requisite quantity from the market and gives them to the original buying member. Auctions are generally held on Wednesday/Thursday.
If the shares could not be bought in the auction i.e. if the shares were not offered for sale in the auction, the Exchange squares up the transaction as per SEBI guidelines. The guideline in force stipulates that the transaction is squared up at the highest price on the NSE from the relevant trading period till the auction day or at 20% above the last available closing price on the NSE, whichever is higher. The pay-in and pay-out of funds for auction square up is held along with the pay-out for the relevant auction.
