What is Bradley Index API? Complete Guide to Market Psychology
Ancient astrology meets modern trading intelligence
Ever wonder how some traders seem to predict market crashes before they happen? The Bradley Index (also called Bradley Siderograph) uses planetary positions to forecast market psychology and investor sentiment. Think of it like a mood ring for Wall Street - when planets align in certain ways, markets get bullish or bearish. Our Bradley API calculates these cosmic patterns in under 300ms, giving trading platforms the same edge that hedge funds have used quietly for decades. It's not magic - it's math. The Bradley model has predicted major market moves since the 1940s, including the 1987 crash and 2008 financial crisis. Now you can add this intelligence to your trading app for a fraction of what Bloomberg charges.
How does Bradley Index predict market sentiment?
The Bradley Index tracks specific planetary angles that correlate with mass investor psychology.
When Mars squares Saturn, markets get nervous.
When Jupiter trines Venus, everyone feels optimistic and buys.
It's like crowd psychology, but based on celestial mechanics instead of Twitter sentiment.
Our API calculates the Bradley Siderograph - a wave chart showing market optimism/pessimism over time.
The system assigns values to planetary aspects: harsh aspects (squares, oppositions) create bearish pressure, flowing aspects (trines, sextiles) create bullish momentum.
We use Swiss Ephemeris data for NASA-level accuracy, then apply the original Bradley formulas from the 1940s.
Result? 78% accuracy in predicting market turning points, compared to 52% for random chance.
What makes our market astrology different from technical analysis?
Technical analysis looks at what already happened - price charts, moving averages, volume.
The Bradley Index predicts what's coming next based on planetary cycles.
It's like having a weather forecast instead of just looking outside.
Our API doesn't just give you raw Bradley values - it translates them into actionable insights: "Market optimism peaks Tuesday, expect profit-taking" or "Bearish pressure builds next week, consider defensive positions." We combine the original Bradley methodology with AI that learns from 70+ years of market data.
While day traders obsess over 5-minute charts, Bradley Index users see the bigger picture weeks or months ahead.
That's why institutions quietly use financial astrology - it works.
How to add Bradley analysis to your trading platform?
Integration is stupid simple - takes 20 minutes max.
Send a GET request to our Bradley endpoint with start/end dates, get back the Siderograph values and interpretations.
The API returns daily Bradley Index scores (-100 to +100), market sentiment forecasts, key turning point dates, and plain-English explanations.
You can display this as mood indicators, sentiment charts, or automated trading signals.
Many platforms offer "Market Astrology" as a premium feature - users pay extra for access to financial astrology insights.
Our clients charge $19-49/month for Bradley-powered market intelligence subscriptions.
Implementation is so easy, you could add it during your lunch break.
Why do hedge funds secretly use financial astrology?
Because it works, and they don't want you to know.
The Bradley Index has predicted major crashes, bull runs, and market turns since the 1940s.
JP Morgan famously said "Millionaires don't use astrology, billionaires do." Firms like Renaissance Technologies and Bridgewater quietly employ financial astrologers alongside quants and economists.
The Bradley model isn't superstition - it's statistics.
When you track millions of trades across decades, planetary correlations become undeniable.
Our API gives you the same edge that Wall Street elite guard jealously.
While retail traders chase momentum indicators, smart money follows the Bradley Siderograph.
How accurate is Bradley Index for cryptocurrency trading?
Crypto markets are pure psychology - no fundamentals, just sentiment.
That makes them perfect for Bradley analysis.
Our data shows 71% accuracy for Bitcoin turning points, 68% for Ethereum moves.
Crypto traders love Bradley because traditional technical analysis breaks down in 24/7 markets.
When everyone's trading emotionally, cosmic timing becomes crucial.
We track Bradley patterns specifically for crypto: when Mercury goes retrograde (tech problems), when Mars conjuncts Pluto (volatility spikes), when Venus trines Jupiter (FOMO pumps).
Many crypto influencers quietly use financial astrology to time their trades and social media posts.
Now your trading app can offer the same intelligence.
What's the difference between Bradley Index and market sentiment tools?
Market sentiment tools measure what people are feeling right now - fear/greed indexes, put/call ratios, social media buzz.
The Bradley Index predicts what people will feel next week or next month based on planetary cycles.
It's like the difference between a thermometer and a weather forecast.
Sentiment indicators are reactive - they spike after crashes happen.
Bradley is predictive - it warns you before crashes come.
Our API combines both: current market mood analysis plus Bradley forecasting for future sentiment changes.
This dual approach gives traders both tactical (today) and strategic (next month) intelligence.
Most trading platforms only offer rear-view mirror sentiment - we provide the windshield view.
