Variational questions

Does Variational charge trading fees?

No. Omni has no maker or taker fee; the cost is built into the spread of the price it quotes.

How does CostDepth measure Variational's cost?

From Variational's own quotes for $1k, $100k and $1M orders, compared with the mid price. In between, cost is spread evenly.

What does a $100,000 Variational BTC trade cost?

No fee, plus the spread in its $100k quote at that moment, shown above.

Does the Variational referral code lower fees?

No, there is no fee to lower. Code OMNIKINGNAT is a referral link only.

Why is there no order book for Variational?

Variational works by request for quote (RFQ): a market maker prices your order instead of a public book.
