ThinkMarkets expands synthetic indices range with leverage up to 1:10,000

October 6, 2026

We have added two new instruments to our synthetic indices range: Overdrive 10 and Calm 10. They join Weekend Storm, a recent addition, alongside our Volatility, Boom, Crash and Jump indices. Each index is designed with its own price behaviour.

Overdrive 10

Overdrive 10 typically holds its level, then moves in a single unpredictable step up or down. There is no build-up before a jump and no trend between jumps. It is priced twice per second by ThinkMarkets' proprietary pricing engine.

Overdrive 10 offers leverage up to 1:10,000, the highest available on any of our instruments. At maximum leverage, the margin requirement is 0.01% of the position value. This means a single price step can gain or lose a large proportion of your margin, and a position can be stopped out very quickly.

Calm 10

Calm 10 is designed for gentler price movement, with smaller swings than higher-intensity synthetic indices. Smaller swings do not remove risk, particularly when trading with leverage.

A wider choice of price behaviour

Synthetic indices are generated by a pricing engine rather than tracking a real market. They are not directly affected by economic data or news, and they can be traded 24 hours a day, seven days a week, including weekends and public holidays. The range now covers a wide spread of behaviours:

Calm 10: gentler movement
Volatility: constant movement, from mild to intense
Boom and Crash: sudden spikes and drops that occur at random
Jump: sharp moves in either direction
Weekend Storm: index-like trends and quiet spells, livelier at the weekend
Overdrive 10: long periods of little movement followed by sudden steps

Guaranteed stop-loss orders with no premium

Guaranteed stop-loss orders (GSLOs) on synthetic indices now carry no premium. Minimum stop distances apply. Standard stop-loss orders are not guaranteed and may be filled at a worse price during sudden moves.
