Specific leverage offerings for Delta Asia Financial Group are not detailed in the available data. In general, leverage can vary by account type and instrument. However, the risk associated with trading with this entity is objectively assessed as extremely high, irrespective of leverage. This assessment is based on its unregulated status, revoked license history, suspicious business scope, and critically low WikiFX score. The fundamental risk of engaging with an unregulated entity far outweighs any specific trading risk posed by leverage ratios.
