How do non-crypto assets differ from digital assets?
Non-crypto assets work the same way as digital asset instruments for order types, leverage, fees, and account rules. The only difference is what they track: price exposure to an equity index or commodity market instead of a digital asset.
Two things to keep in mind:
Non-crypto assets confer no dividends, no shareholder rights, and no physical delivery. They are price-exposure instruments only.
The markets they track have defined or near-continuous underlying hours, which affects pricing outside those hours. See What are the trading hours for non-crypto assets?
