About Viktury

If you trade perps, your PnL depends on whether the contract is linear or inverse, on the funding you paid or collected while the position was open, and on fees that pile up over hundreds of fills. Most journals either skip those or count them wrong, so the numbers you review at the end of the week don't match what your exchange did to your balance. That defeats the point of keeping a journal.

Viktury syncs straight from your exchanges and does the PnL math on the server, correctly, for both linear and inverse contracts. It tracks funding and commissions as real numbers, values your holdings across venues over time, and gives you the journaling and analytics on top. Tag your setups, review your trades, and see whether the edge you think you have actually shows up in the data.

It works with Binance, Bybit, Coinbase, Deribit, Hyperliquid, and Revolut today, with more on the way.

Who's behind Viktury

Viktury is a small, independent company built by Utku Demir, a data and cloud engineer with eight years spent designing scalable, reliable systems, most recently at a large tech company. The discipline that keeps systems like that correct at scale is the same thing we care about here: get the hard math right, and never show you a number your exchange wouldn't.

Utku trades the markets Viktury is built for. Spot and perps, linear and inverse, across crypto, commodities, stocks, and indices, on Bybit, Coinbase, Binance, Deribit, Revolut, Interactive Brokers, and DEGIRO. When a number looks off, we see it in our own journal first.
