Initial commit: Oil Trading Bot (MT5, WTI)
Headless FastAPI-Backend (server.py + core/engine.py) mit Mobile-PWA (web/), Strategie-/Backtest-Suite und Doku. Secrets, DB, Logs und Laufzeit-State sind via .gitignore ausgeschlossen; Config-Vorlage: oil_widget_config.ini.example. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

|
||||
//| SR_Levels.mq5 |
|
||||
//| Zeichnet Support-/Resistance-Linien + Zonen (Ranges), die der |
|
||||
//| Python-Bot (Oil Trading Server) nach MQL5\Files\sr_levels.csv |
|
||||
//| schreibt. Das Python-MetaTrader5-Paket kann selbst KEINE Chart- |
|
||||
//| Objekte erzeugen — daher diese Datei-Bridge. |
|
||||
//| |
|
||||
//| Installation: |
|
||||
//| 1) Diese Datei nach <Terminal>\MQL5\Indicators\ kopieren. |
|
||||
//| 2) In MetaEditor öffnen und mit F7 kompilieren. |
|
||||
//| 3) Im Navigator auf den WTI-Chart (SpotCrude) ziehen. |
|
||||
//| 4) Der Bot muss laufen (schreibt die CSV alle ~5 s). |
