A majority of the futures markets are very liquid, particularly the most commonly traded commodities, currencies, and indexes. This reassures that traders can enter and exit positions when required.
Futures are cheaper in relation to the market exposure you get with one contract. With low commissions and low slippage, futures are a low-cost alternative to other securities.
Standardized contracts for a broad selection of asset classes, e.g. commodities, energies, metals, equities, indices, and interest rate markets are all available to trade as futures.
With superior technology, the low spreads have made this a market available to almost everyone.
