Hey Product Hunt, maker here. I built Viktury because I trade crypto and every journal I tried treated it like an afterthought. Inverse contracts confused them, funding and fees were wrong, and BTC-denominated PnL just was not a thing. So I built the journal I wanted: it connects to my exchanges, imports every fill, and gives me the review layer I actually use to find my own mistakes. I started with crypto because that is where the math is hardest, inverse PnL, funding, BTC-denominated PnL, and it is where Viktury is strongest today. It is not staying crypto-only, but I would rather get each market right than list a lot of them on day one. A few things I am proud of: - Auto-sync with read-only API keys, so you are never handing over withdrawal access. - A cost-of-mistakes chart that turned my vague "I overtrade" into an actual number. - Bar-by-bar replay for reviewing setups without touching your live stats. Every account includes a read-only demo, so you can look around before connecting an exchange. For the first 50 people, the code FOUNDER at checkout takes 50% off your first 6 months, before 16 October. I am here all day and would genuinely love feedback, especially on what is missing for your workflow. What would make this a daily tool for you?
