Riskalyze (now Nitrogen) is a portfolio risk analysis platform used by advisors, not day traders. The question is not whether the Risk Number scoring works — 20,000+ advisor firms use it — but whether you are the intended audience. Most active traders reading this are not.
This review synthesizes Riskalyze/Nitrogen's public documentation and stated advisor-industry positioning. For current pricing and firm-tier options, use the official Nitrogen site.
The Risk Number is the whole product
Riskalyze assigns a patented 1-99 Risk Number to any portfolio, quantifying downside exposure based on historical volatility, position sizing and asset-class distribution. The advisor then discusses that number with the client to align portfolio construction with the client's stated risk tolerance.
That is the entire value proposition. It is not a scanner, not a screener, not a backtester, not a trading platform. If your workflow is entering and exiting positions, Riskalyze is not the tool. If your workflow is helping other people understand risk in their portfolios, it is best-in-class.
Built for financial advisors, not retail traders
The intended user is an RIA, CFP or wealth advisor managing client portfolios. Riskalyze integrates with major custodians (Schwab, Fidelity, Pershing) and portfolio-management systems. Pricing is enterprise-tier — advisor firms pay meaningful monthly subscriptions per user.
Retail traders will not benefit from this. If you want to analyze your own portfolio's risk, use Stock Rover's portfolio analytics or a broker-provided risk view. Riskalyze is priced and structured for firms with fiduciary responsibilities.
Compliance + client-communication use case
The real reason advisors pay for Riskalyze is client communication and compliance documentation. Assigning a Risk Number to both the client's stated tolerance and the actual portfolio gives a documented, defensible measurement of alignment. When markets drop and clients ask "why am I losing money," the advisor can point to a signed risk number that matches the portfolio's expected drawdown.
That documentation defends the firm against later "you never told me the risk" complaints. It is genuinely valuable in a regulated industry. It is completely irrelevant to a retail trader trading their own account.
The Nitrogen rebrand
Riskalyze rebranded to Nitrogen. The Risk Number remains central but the platform expanded into broader wealth-management workflow — planning, proposals, compliance documentation, marketing. The rebrand reflects a move from single-purpose risk tool to broader advisor productivity suite.
Existing customers report the transition has been mostly seamless. New evaluators should look at the full Nitrogen suite rather than just the legacy Risk Number scoring.
What Riskalyze / Nitrogen does not do
No trade execution. No real-time market data. No charting. No stock screening. No options analytics. No backtesting. All of these are outside the advisor-facing scope.
For any of those workflows, use a proper trading platform: thinkorswim for options, TradingView for charts, Finviz or Stock Rover for screening, QuantConnect for backtesting.
Who should actually use Riskalyze / Nitrogen
Registered investment advisors, CFPs, wealth managers, and RIA firms managing client portfolios who need documented risk alignment for compliance. Enterprise-tier — pricing and workflow assume a firm, not an individual trader.
For retail investors curious about portfolio risk, use free tools: portfolio analytics inside your broker platform, or Stock Rover's free tier for portfolio risk views.
Our current assessment
Riskalyze / Nitrogen is the reference tool for advisor-industry risk documentation. For its intended audience it is genuinely differentiated. For retail traders it is the wrong tool at the wrong price. If you are here from a search for "portfolio risk tool" and you trade your own account, look at Stock Rover, TipRanks Portfolio Manager, or Seeking Alpha Portfolio instead.
