“Boom” and “Crash” indices refer to synthetic indices offered by certain brokers or trading platforms. These indices are designed to simulate the price movements of markets during boom or crash periods.

The Boom index represents a simulated market that is experiencing an upward trend or a “boom” period. It aims to capture the potential gains and positive price movements that can occur in a thriving market.

On the other hand, the Crash index represents a simulated market that is undergoing a downward trend or a “crash” period. It aims to reflect the potential losses and negative price movements that can occur during a market downturn.

These synthetic indices are usually created using algorithms and historical market data. They provide traders with the opportunity to speculate on the price movements of these simulated markets without directly trading the actual underlying assets.
