About this app
Have you ever looked at a stock chart and thought, "I have seen this pattern before"? Deja finds historical charts that match your current pattern and shows you what happened next.
Deja scans thousands of historical price patterns across stocks and crypto to find the ones most similar to the chart you are looking at right now. Then it tells you, with real statistics, how those similar patterns played out -- whether prices went up or down, and by how much.
CORE FEATURES
-- Pattern Matching Engine
Deja identifies similar historical chart patterns across NASDAQ, NYSE, and crypto markets. Each match includes a similarity score so you know how closely it resembles the current chart.
-- Statistical Predictions
For each set of matched patterns, Deja calculates 1-day and 5-day predictions including win rate, maximum gain, maximum loss, IQR range, and median outcomes. No guesswork -- just data.
-- Interactive Comparison Charts
Overlay the current chart with any historical match to visually compare how patterns align. Switch between line and OHLC views. See exactly where the "similar part" is and what happened after.
-- Customizable TP/SL Levels
Set your Take Profit and Stop Loss using the metric that fits your trading style -- Max, Min, IQR bounds, or Median values. The chart updates in real time to show your selected levels.
-- Live Price Data
Real-time price updates via WebSocket with historical data merged seamlessly. Watch the current pattern develop as it happens.
-- Multi-Market Coverage
Browse and analyze charts from NASDAQ, NYSE, NYSE-ARCA, and major cryptocurrency pairs.
