The fee is currently locked at 0.1% of the position size for opening and closing of long and short positions. Transaction Fee (trading fee, swap fee): levied on each trade executed on vDEX and calculated as a percentage of the total transaction value. These fees contribute to the operational costs of running vDEX, including security, user support, technology upgrades, and other infrastructure costs. The transaction fee is currently locked at 0.1%. Funding Fee (borrow fee, cost of carry): associated with holding positions that are leveraged or held overnight to compensate the counterparty for the risk they take on by providing leverage. The funding fee is calculated every 4 hours. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
