Where do I add purchase and sell dates when entering a portfolio?

You don't need to add purchase or sell dates.

Our portfolio analytics looks at the latest portfolio that you currently hold. It analyses this portfolio in many different ways to help you decide whether or not to change it.

We run a back-test (or hypothetical) to see what this portfolio would have done in the past. This is important to look at since the portfolio that you currently hold is what will decide what happens from tomorrow. The transactions that happened before today in your portfolio have already had their effect - what matters is the return you deliver going forward - and that is only affected by your current portfolio.

NGEN Markets does not provide a reporting service to show the actual P&L of a given set of transactions. Your back office system is much better suited for this.

You should use NGEN Portfolio analytics to help you guage your current portfolio and make a decision about whether or not to change it, as well as come up with new portfolio ideas by backtesting them.
