Checking Risk Before You Commit

Before you put a trade on — or while you're holding one — the questions that matter are simple: how likely am I to come out ahead, what's the range of outcomes, and how bad could a bad day get? The Risk Lab answers them. It simulates your positions and shows a plain-language verdict, the range of outcomes as a cone, and — the "before you commit" part — lets you test what-if changes without touching your real book. Open it from the top navigation.

Important

The Risk Lab is a model — a simulation of what might happen, not a forecast of what will. VolNinja never gives trading or financial advice. Treat its numbers as guidance, not direction: a way to weigh your own decision, never a recommendation to trade, a guarantee, or an opinion on what you should do. Real markets move outside any model's expectations, and every decision is yours.

The verdict at a glance

At the top sits the verdict banner: a colored dot and a one-line read — "You're in good shape", "Worth watching", or "High risk" — based on your chance of profit. Alongside it are the numbers behind it:

  • Current P&L — where you stand right now.
  • Chance of profit — how often the simulated outcomes finish above break-even.
  • Expected value — the probability-weighted average outcome (your long-run edge); the EV/R figure compares it to your downside.
  • Median Value — the middle outcome.
  • Bad day — a rough-but-plausible loss; only about 5% of outcomes are worse.
  • Time to expiry.

Hover any label to see exactly what it means.

Tip

You don't have to open the Risk Lab to get this read — the same verdict banner appears on your Dashboard, so a glance tells you whether your book is in good shape or worth watching.

Try a change before you commit

This is what "before you commit" means. Click What-if and stack up hypothetical actions:

  • Open new — add one of your favorite templates, times a quantity.
  • Close existing — close a whole position, or a single leg.

Press Done — run it, and the Risk Lab re-simulates with your changes applied. The verdict numbers switch to a now → after view, so you can see precisely how the change moves your chance of profit, expected value, and bad-day loss — before you place a single order.

Nothing here touches your real positions — it's a sandbox. Use Clear to return to your live book. When you decide to act for real, you do that from the position itself or by running a template — see Opening & closing positions and Placing a trade.

The bigger picture

Below the verdict, the Risk Lab plots the full shape of your risk — a P&L cone of possible paths to expiration (with a break-even line), a distribution of final outcomes, and how likely each of your management rules is to fire. You can also narrow the view to a single position or judge your whole book at once. For a full tour of those panels, see Risk Lab.

Warning

Because the Risk Lab is a model, a healthy verdict is never permission to stop watching — size and manage every trade as if the market can move against you, because it can. And whatever a scenario suggests, in LIVE mode any real action uses real money — see Paper vs live.
