A bad trade can cost hundreds. A missed reversal can cost more. Cipher Stock gives you 4 timeframes, statistical reversal detection, and news sentiment — before you click Buy.
No card. First scans on us.
You don't need to be right every time. You just need better information before you decide.
Think of it as insurance for your decisions. The dollar you spend here can be the thousand you don't lose.
Every prompt below is a real interaction you can have with Cipher Stock in ChatGPT — no learning curve, no dashboards to master.
Real 90-day NVDA data below, running through the exact indicators Cipher Stock uses in production. The formulas stay private — the reasoning is not.
Green markers = statistically oversold (potential rebound). Red markers = statistically overbought (potential pullback).
Most tools tell you "up or down". We tell you what four independent horizons agree on — and where they disagree.
Our model watches 3-day rolling windows of 30-minute bars for statistical extremes — when a stock has moved too far, too fast. Historical patterns show many of these setups revert within 1–5 trading days.
Type a question in ChatGPT the way you'd ask a friend. Plain English, or your language.
Cipher Stock pulls real-time market data, runs multi-horizon signals, checks news sentiment, and detects reversals — in seconds.
Get a structured card. No raw JSON, no hidden formulas. Just the reasoning you need — before you click Buy.
Every output is labeled as a model view. The decision remains yours.
Signals refresh with the market. Snapshot timestamps are always shown.
Free tier to try. Simple credit packs when you're ready. Pay only for what you use.
Vanilla ChatGPT can talk about stocks but can't pull current prices or run technical indicators on its own. Cipher Stock is a Custom GPT that connects ChatGPT to a live stock-analysis backend: RSI, z-score, multi-timeframe rating, reversal detection, and news sentiment are computed on real market data and returned as a structured answer.
Yes — the free tier lets you try full analyses without a credit card. Credit packs are available if you want to run more scans per day. No subscription, no auto-renewal.
The scanner scores every tracked symbol every trading day. A stock is flagged as oversold when RSI drops below 40 and the 20-day z-score is under −1 while the short-term slope stays negative — three independent signals aligning on the same side. Overbought uses the mirror image. Only symbols that clear all rules are surfaced.
A single timeframe lies. A stock can be in a 6-month uptrend, a 1-month pullback, a 1-week bounce, and a 1-day pullback — all at once. Cipher Stock runs the analysis on four horizons (6 months, 1 month, 1 week, 1 day) and combines them into one final rating so short-term noise doesn't override a healthy long-term trend.
No AI predicts prices. What Cipher Stock does is compute the same statistical signals professional traders check — faster and without emotion. Every response includes the underlying numbers (RSI, z-score, slope, news sentiment) so you can verify the reasoning instead of trusting a black box.
Most stock GPTs summarize news or paraphrase Yahoo Finance. Cipher Stock runs a proprietary reversal-detection algorithm on live market data, exposes multi-horizon ratings, and returns concrete Safe Buy / Safe Exit levels — not just narrative.
