Red Candle is a desktop trading journal for forex and gold traders. It keeps trade records, chart screenshots, pre-trade checklists, MetaTrader 5 (MT5) candle data, and results together on the user’s computer. Traders can add a screenshot to a journal entry, with the app placing it at the relevant chart time and detecting the symbol and timeframe from supported TradingView filenames. The app opens a pre-trade checklist when a user logs a trade and can restrict logging when daily trade or loss limits are reached. Users can import MT5 “Export Bars” CSV files with broker time zone information, review charts with automatically calculated trends, key levels, and gaps, and search historical candles for setups with similar market structures. AI analysis can explain chart structure using a connected OpenAI or Anthropic account, or a local model through Ollama or LM Studio. The app calculates market structure, while AI provides explanations. Red Candle is a local-first application. Trades, screenshots, and candle data remain on the computer unless the user chooses to share them, such as by sending data to a connected cloud AI service. Account details and AI keys are stored in the computer’s secure keychain, and an online account is used to unlock the app license. The app is available for macOS 12 Monterey or later on both Apple Silicon and Intel Macs. A Windows version is planned for Windows 10 version 2004 or later, or Windows 11, on 64-bit systems with WebView2. The software is free to download, but a paid subscription is required to use it, with no free trial.
