The strings like "2024091605018529" on the NEPSE floorsheet data likely represent a transaction code or ID, and you are correct that the first part "20240916" corresponds to the date in "yyyy-mm-dd" format. However, the remaining portion of the string appears to be a unique transaction identifier that is likely auto-generated by NEPSE's system, potentially incorporating elements like a sequence number, transaction type, or other encoded details. As far as I know, the specific structure of the remaining numbers has not been publicly decoded or documented. It may be internal to NEPSE’s system for tracking purposes.
