Why is my average rate incorrect after receiving shares from a merger/de-merger/amalgamation?

The details of shares received through off-market transfers, dematerialization, IPOs, or corporate actions such as rights issues, mergers, etc., cannot be determined by the system. Similarly, in cases where there is a short delivery of shares resulting in an auction, the transaction will reflect as a sell entry followed by a buy entry through the auction. This can break the FIFO chain, making it difficult for the system to determine the correct purchase rates. Hence, such transactions need to be manually entered and updated by the client in MyGeojit to ensure that the correct cost and transaction details are reflected.
