Portfolio NAV and other analysis reports require full historical data of price bought and price sold. However, data provided by brokers during portfolio only consists of current holdings data and not the historical data. As a result, these reports cannot be generated for portfolios imported from brokers. 

To get Portfolio NAV and other analysis for your portfolio, download your portfolio data from your broker, and upload it to Trendlyne via xls/csv from the upload portfolio via excel option.
