Yes, a Cryptocurrency exchange script supports spot, futures, and margin trading, but it depends on the specific script and the provider you choose. 

Usually, spot trading can be integrated easily, but it is difficult to integrate margin trading because it requires a more sophisticated setup, including a powerful matching engine, risk management system, liquidation logic, and leverage configuration. So, not all scripts come with advanced trading models. 

But with the right development provider, you can get your customised script with spot trading (basic buy/sell, order types, live order book), Margin trading (leverage options, borrowing, auto-liquidation), and Futures trading (perpetual or delivery futures, funding rates, risk engine).  They make it possible to run all three markets on a single platform.
