Investing tools explained: trackers, screeners, calculators, alerts and simulators

Tracking

A portfolio tracker pulls your holdings from your accounts so you can see everything together: total value, allocation and gains. A net worth tracker adds cash, property and debt. Check that the tool uses read-only connections and does not move money.

Analysing

• Portfolio analyser: shows concentration, sector exposure, correlations and risk.
• Diversification and rebalancing tools: show how far you have drifted from target.
• Risk analysis: volatility, drawdowns and which holding dominates your results.

Researching

• Screeners and scanners: filter the market by your criteria.
• Comparison tools: place two or more stocks or funds side by side.
• Earnings and dividend calendars: show upcoming dates for the companies you follow.
• Watchlists and alerts: keep candidates in one list and tell you when something changes.

Planning

Calculators for compound interest, retirement, dividends, DCA, ROI, inflation and capital gains turn assumptions into numbers. They are best used for scenarios: change one assumption at a time and see what moves most. Results depend entirely on the inputs.

Practising

Simulators and paper trading let you test ideas with virtual money. Backtesters replay a strategy against real historical prices.

How often to check

For a long-term investor, daily checking mostly adds anxiety. A weekly glance and a deeper quarterly review are plenty for most people. Alerts can cover the rest.

A tool is only as good as the decision it improves. Keep the routine small enough that you will actually follow it.
