Signodex is a research desk in your pocket. Not a feed of tips โ€” a panel of specialists that takes one asset apart, disagrees out loud, and keeps score of how often it was right. THE ANALYST DESK Pick a venue, pick an asset, choose how deep to go. Six specialists then go to work in parallel: โ€ข Technical โ€” trend, structure, and where price has repeatedly turned โ€ข Fundamental โ€” valuation for equities, issuance and network economics for crypto, carry for currencies โ€ข Macro โ€” rates, the dollar, liquidity, and how the instrument moves with the broad tape โ€ข Sentiment โ€” news flow and how positioning is leaning โ€ข Risk โ€” argues against the emerging consensus and names what would invalidate it โ€ข Chief Strategist โ€” reconciles every seat and states which arguments were discounted, and why The risk seat exists so the desk cannot produce agreeable mush. The chief must reconcile disagreement rather than average it away. A RECORD YOU CAN CHECK Every verdict is recorded and later scored against trusted market prices at 24 hours and 7 days. The results are published with confidence intervals rather than a single flattering number. Most tools tell you what they think. This one also tells you how often it has been right. 24 ASSET ROBOTS Per-symbol analysts covering crypto, equities, metals and currencies. Each publishes a daily read with its own accuracy record attached. MARKETS โ€ข Crypto โ€” live prices and real candles โ€ข Equities โ€” NASDAQ, NYSE, XETRA, LSE, Euronext, SIX, Tokyo, Hong Kong, Sydney โ€ข Fundamentals โ€” P/E, forward P/E, EPS, dividend yield, market cap, 52-week range, reported in the currency the issuer actually filed in โ€ข Metals and major currency pairs TOOLS โ€ข Charts with candlestick, Heikin-Ashi and area modes, and full-screen landscape โ€ข RSI, MACD, Bollinger Bands, EMA, VWAP โ€” with an indicator academy that explains what each one measures โ€ข Instrument alerts on direction, confidence, price and percentage move โ€ข Portfolio tracking and a watchlist that follows your account, not your handset โ€ข Works offline with last-known prices, clearly marked with their age BUILT FOR PROFESSIONALS Eight languages. Full VoiceOver support. Dark and light themes. iPhone and iPad.
