As answered by people managing JavaScript Operator Lookup and Prop Trading Stat.
Prop Trading Stat's answer:
Prop Trading Stat serves individual traders rather than institutions. Due to privacy policy, we do not disclose the names of our users.
Prop Trading Stat's answer:
Prop Trading Stat is the only app built exclusively for prop firm traders — not a generic finance tracker adapted for trading, but a tool designed from scratch around the specific needs of this world: challenge fees, resets, payouts, and multi-firm ROI. It requires no broker connection, no API, no credentials — just manual entry, which means it works with every prop firm on the market, today and in the future.
Prop Trading Stat's answer:
Most prop traders still track their performance on spreadsheets or generic budgeting apps that don't understand the prop firm model. Prop Trading Stat speaks the language of funded traders natively: challenge fees, resets, payout cycles, ROI per firm. It combines a free forever plan, mobile apps on iOS and Android, and advanced analytics — streak stats, firm comparison, calendar heatmap, Excel exports — in a single tool built specifically for this niche.
Prop Trading Stat's answer:
Prop firm traders at any level — from those running their first challenge to full-time funded traders managing multiple accounts across several firms simultaneously. Anyone who spends money on challenge fees and receives payouts and wants to know if they are actually profitable net of all costs.
Prop Trading Stat's answer:
The founder is a prop trader himself. Like most traders, he was tracking challenge fees, resets, and payouts on Excel spreadsheets — and realized how inefficient and incomplete that picture was. There was no way to quickly see real ROI across multiple firms, spot losing patterns, or understand which firms were actually worth it. So he built the tool he wished existed.
