Deriv Boom and Crash Indices: Spikes Explained

Boom and Crash indices drift steadily and then jump. Understanding the spikes is the whole game, and it is a hard one.

Last updated October 28, 2026

How Boom and Crash indices move

• Boom indices drift slowly downwards and occasionally spike up sharply.
• Crash indices drift slowly upwards and occasionally spike down.
• The number in the name (for example Boom 1000 or Crash 500) is the average number of ticks between spikes.

Spikes are random in time

"On average every 1,000 ticks" does not mean a spike is due after 1,000 quiet ticks. Spikes arrive at random: one can follow another closely, and long gaps are normal. A long gap does not make the next spike more likely.

Drift versus spike

Positions that follow the drift collect small moves most of the time and take a large hit when a spike arrives. Positions that bet on the spike usually lose a little per tick while they wait. Neither side has a built-in advantage; the trade-off is between frequent small results and rare large ones.

Using spike statistics

The Analysis Tool's Boom/Crash mode shows the history of detected spikes, the distribution of intervals between them and of spike sizes. These describe the index's behaviour and help you size positions for the moves that actually happen. They do not predict when the next spike will come.

Tradion bots and Boom/Crash

None of Tradion's current bots trade Boom or Crash indices. The spike analysis is available as a free tool for your own research.
