What are Boom and Crash indices?
Boom and Crash are synthetic indices defined by periodic spikes. Boom indices spike up on average every 500 or 1000 ticks; Crash indices spike down every 300, 500 or 1000 ticks. They run 24/7, ignore economic news, and reward traders who can read the rhythm between spikes.
Boom 500 & 1000
Upward spikes on average every 500 or 1000 ticks — the lower the number, the more frequent the spike.
Crash 300, 500 & 1000
Downward spikes every 300, 500 or 1000 ticks, with smooth drift in between.
