Don't Just Read the Chart. Learn What Happened Before.
PatternForge AI compares current price patterns with historical market data, replays what happened next, and presents evidence-based BUY, SELL, HOLD, or NO SIGNAL results with measurable risk levels.
Actual values depend on the instrument, timeframe and available historical evidence.
What if you could test a chart pattern against market history?
A chart may look familiar. But visual similarity alone does not tell you what happened after that pattern appeared in the past. PatternForge AI takes the comparison further.
Read the Chart
Identify the instrument, timeframe and recent price structure.
Find Similar Patterns
Compare the current pattern with comparable historical formations.
Replay the Outcomes
Test what happened next against defined stop and target levels.
Review the Evidence
See BUY, SELL, HOLD or NO SIGNAL with the supporting measurements.
More than a chart signal
Bring chart analysis, risk planning and trade journaling together.
Tools to make your trading process more measurable
PatternForge AI combines historical chart analysis with practical tools for reviewing signals, managing risk and tracking performance.
Historical Pattern Engine
Compare the current 30-bar price shape with earlier, non-overlapping historical windows on the same instrument and timeframe.
BUY / SELL / HOLD Analysis
Directional results are based on historical replay evidence. HOLD and NO SIGNAL remain valid outcomes when evidence is insufficient.
Entry, Stop Loss and Targets
Review calculated entry, stop-loss, TP1 and TP2 levels when a valid directional result exists.
Trade Journal
Record trades and review expectancy, profit factor, drawdown, winning and losing streaks, and performance breakdowns.
Risk Calculator
Work with account balance, risk percentage, entry, stop-loss, target and position-size information.
Watchlist Scanner
Review watchlist quotes and, with the Pro scanner, compare historical replay results across symbols.
Market Sessions and Calendar
Check market sessions, upcoming opens and closes, and economic calendar events.
Optional AI Explanations
Use a configured AI provider for written explanations. AI does not override the quantitative signal or its price levels.
Command Center
Manage signals, journal, scanner, alerts, risk calculator, API providers and extension settings in one place.
Not every chart deserves a BUY or SELL signal.
PatternForge AI evaluates resolved historical analogue trades. The result makes the available evidence visible instead of hiding a small sample behind a confident-looking signal.
These are evidence classifications, not guarantees of future performance. Historical results do not predict future market outcomes.

Your trading decisions stay yours.

Read the Privacy Policy →Frequently asked questions
Important details before installing PatternForge AI.
Is PatternForge AI free?
Yes. The Free plan does not expire. It includes two symbols, three AI uses per UTC day, and limited saved signals, watchlist, alerts, accounts and journal entries.
Does it automatically execute trades?
No. PatternForge AI is an analysis-only extension. It does not place, modify or close broker orders. You remain responsible for every trading decision and order.
How does the historical pattern engine work?
It compares the recent 30-bar price shape with earlier, non-overlapping historical windows on the same instrument and timeframe. Comparable patterns are replayed forward to measure what happened next against defined stop and target levels.
Why does the card sometimes show HOLD or NO SIGNAL?
These are deliberate results. If the historical replay does not provide enough resolved evidence for a directional call, the extension avoids inventing a BUY or SELL result.
Do I need an API key?
Not for every data source. Yahoo Finance is a keyless source for supported instruments, while Binance and CoinGecko are also keyless for crypto. For more dependable FX history, you can configure a provider such as Twelve Data or Finnhub.
Does the AI decide the entry, stop-loss and target?
No. The historical engine and calculation logic determine the quantitative result and price levels. Optional AI explanations can describe a setup but cannot override those levels.
Which browsers are supported?
PatternForge AI is available through the Chrome Web Store and Microsoft Edge Add-ons. Some chart websites may require you to enable site access.
Does historical performance guarantee future profits?
No. Historical comparisons are research evidence, not a guarantee or prediction of future results. Trading involves substantial risk of loss.
