How do non-crypto assets differ from digital assets?
Non-crypto assets work the same way as digital asset instruments for order types, leverage, and account rules. They differ in what they track, which is price exposure to an equity index or commodity market instead of a digital asset, and in the trading fee: 0.02% on every buy or sell order for non-crypto assets, compared with 0.04% for crypto assets.
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?
