About PairSync: 3rd Person StatArb
PairSync is the first 3rd-Person StatArb Strategy on mobile. A live quantitative strategy. Running continuously across global markets. You watch it from the outside -- and choose which pairs it runs on. The watchlist is where you become the curator You don't control the strategy's rules -- but you decide which pairs it runs on. Start with the pre-built Market Leaders or construct your own from any eligible pair in the feed. Every pair you add shows the full strategy output on that pair: open positions, historical signals, live Z-score spread, backtest track record. Two curators with identical watchlists see identical output -- the strategy runs the same rules for everyone. What differs is the universe you choose. The system runs continuously, 24/7 Filtering millions of potential asset combinations through sector pairing and market cap alignment, then applying Engle-Granger cointegration analysis to isolate eligible pairs, calibrating entry and exit parameters for each, ranking them across seven factors, and delivering continuously curated Market Leaders lists across US equities, European markets, ASX, NSE, and crypto. It enters positions. It exits them. It logs every signal. You watch. WHAT THE PLATFORM DOES PairNet AI -- nothing reaches the feed without proof Every pair clears hard statistical filters -- Engle-Granger cointegration p-value, Hurst exponent below 0.5, half-life between 2 and 60 days, and a completed backtest -- before entering the scoring pool. Survivors are ranked across seven factors: Sharpe (25%), cointegration strength (20%), win rate (20%), time efficiency (15%), stability (10%), hedge naturalness (5%), market cap quality (5%). The top pairs reach the mobile feed. Calibrated daily. Frozen at signal. PairNet AI re-optimises entry and exit thresholds and Kalman-filtered hedge ratios for every pair, daily. The moment a signal triggers, those parameters freeze for the life of that trade -- the strategy follows its real-world outcome, untouched by the continuing optimisation cycle. Success keeps the pair. Failure replaces it. The track record is open Every pair shows its backtest Sharpe ratio, win rate, average duration, and equity curve -- the historical performance PairNet AI calibrated against. Nothing is hidden. Strategy Positions -- live from entry When the strategy enters a position, PairSync logs the entry Z-score, direction, and date. Strategy Positions tracks every open position from entry forward. The spread meter shows where the pair sits relative to its signal threshold right now. Signal Log -- every call on record Every signal the strategy has fired -- outcome, direction, duration, Z-score at entry. Exportable to spreadsheet. Take the data with you Strategy Positions and Signal Log are fully exportable -- structured for basket construction, position sizing by AUM, and high-touch brokerage execution. One tap. Signal pairs only. Coloured accent strips show signal state before you read a single number. WHO USES PAIRSYNC For traders who think in systems. For quants who want to observe a live strategy in production -- not a simulation. For finance students learning from real market data, not a textbook. FREE TRIAL 30 days. Full access.
