How to tell Derived Indices apart by chart shape

A digital trading dashboard displaying financial charts with distinct derived index patterns, including oscillating volatility channels and staircase price levels.

Deriv's Derived Indices come in many types: Volatility, Crash & Boom, Crash Boom Flip, Jump, Step (and its variants), Trek, Tactical, Exponential Growth, and Volatility Switch Index. Each one is built from its own math model, and each one looks different on a chart. This guide won't teach you everything about any single index. It's a quick way to tell them apart, with links if you want to learn more about one.

Quick summary

  • Every Derived Index has a shape you can learn to spot.
  • The number in an index's name usually tells you how big or how fast its moves are. Not which direction it will go, or how safe it is.
  • These markets never stop. No weekend gaps, no opening or closing times.
  • Use the table below to look up a shape, then click the links to learn more about that index.

Shape lookup table

Index family What it looks like
Volatility indices Moves up and down around a flat middle line, with no clear direction
Crash indices Climbs steadily, then drops sharply
Boom indices Falls steadily, then spikes sharply upward
Crash boom flip index Switches between crash-like and boom-like stretches. Each sharp move either flips the pattern or doesn't
Jump indices Looks like volatility indices most of the time, but jumps sharply now and then, in either direction
Step index (and multi step, skew step) Moves in a clear staircase of fixed-size steps, not a smooth line
Trek indices Built to keep moving in one direction for longer stretches than volatility indices
Tactical indices Moves in short, sharp bursts rather than a steady drift
Exponential growth indices Built with a steady lean in one direction, unlike volatility indices, which tend to drift back to the middle
Volatility switch index (VSI) Switches between calm stretches and busy, choppy stretches on the same chart

Key takeaway: Ten shapes sounds like a lot to remember. But most of them fall into just a few types. Once you can spot "climb-then-drop," "staircase," and "flat and noisy," you already know most of what you need.

Why the number in the name matters

In several of these families, the number in the name tells you about size or speed, not direction:

  • On Volatility Indices, a bigger number (say, Volatility 100 vs Volatility 10) means bigger price swings over a similar stretch of time.
  • On Crash, Boom, and Flip Indices, the number tells you the average number of ticks between sharp moves. Crash 150 has sharp moves more often, and they're usually smaller. Crash 1000 has them less often, but they're usually bigger.

A higher or lower number isn't "better.” It just changes what you're looking at. Always check which exact index you're on before comparing charts.

These markets never close

Derived Indices come from a math model, not from real people trading on a real exchange. That means there's no opening bell, no closing bell, and no weekend gap. You can check this yourself: open a chart for any Derived Index and scroll back to a weekend. Unlike a forex or stock chart, the price just keeps going. No gap.

This is also why tools built around trading sessions, like opening range or session Volume-Weighted Average Price (VWAP), don't work here. There's no session for them to measure.


How to use this guide in practice

1. From your Deriv dashboard, select CFDs from the left-hand menu, then click Trade on your chosen account (e.g. your MT5 CFDs account) to open its chart. Alternatively, view Derived Indices through a linked TradingView account.

2. Use the table above to spot which family you're looking at, just from its shape.

3. Zoom out. On a Crash/Boom/Flip chart, you'll see the climb-drop or fall-spike pattern.

In contrast, a Step Index chart displays clear, distinct stair-step levels:

Meanwhile, a Volatility Index chart oscillates around a central channel with steady noise:

Closing thoughts

The Derived Indices family is big, but each member has a shape you can learn to recognise at a glance. This guide helps you quickly figure out which family a chart belongs to. The real depth, such as how each one works, its variants, and how to trade it, lives in the linked guides above. A demo account is still the easiest way to get familiar with each shape before you trade for real.

FAQs

If two indices look similar on a chart, how do I tell them apart?

Check the exact name of the instrument. The number in the name (like Volatility 25 vs Volatility 75, or Crash 150 vs Crash 1000) tells you the size or speed you're looking at, even when the shapes look alike at first glance.

Does a bigger number in an index's name mean it's riskier?

Not on its own. It tells you how big or how often the moves are, not which way any single move will go. Bigger or more frequent moves can help you or hurt you, depending on your position.

Why don't Derived Indices have weekend gaps like Forex or Stocks?

Because they come from a math model, not from real trading on a real exchange. There's no session to create a gap, so the price just keeps generating, day and night.

Is a Crash Boom Flip Index the same as trading Crash and Boom Indices separately?

No. A Flip Index switches between a Crash-like stretch and a Boom-like stretch. Each sharp move decides whether it switches or keeps going the same way. Classic Crash and Boom Indices are separate instruments, each one only ever moves in its own fixed direction.

Where can I practise telling these shapes apart without risking money?

A free demo Deriv account lets you watch live charts across the whole Derived Indices family and compare shapes side by side, before you trade with real money.
