Prime Quantum AI is an MT5 Expert Advisor combining a classical pre-filter (ADX + Alligator) with AI vision-based chart confirmation from major AI providers (Anthropic Claude, OpenAI GPT, Google Gemini, DeepSeek, xAI Grok). When the pre-filter detects a trend setup, the EA captures three adaptive- timeframe chart screenshots and sends them to the configured AI provider, which returns direction, confidence, stop-loss and take-profit. A trade is opened only when the AI confirms the pre-filter signal with sufficient confidence. Features: dual Standard Broker / Prop Firm risk modes, configurable lot sizing, optional martingale, multiple SL/TP modes, trailing stop, partial close, news/time/day/spread filters, draggable on-chart info panel, and fully exposed indicator parameters. Requires MetaTrader 5, WebRequest enabled for your provider's URL, and a valid API key. Provider auto-detected from key format.

I want to share with you this story. When I started trading, I learnt the scalping strategy in a volatile market. I really loved scalping especially when I see the price is moving fast. However, scalping for a long period of time is exhausting to me especially in a volatile market; volatile market requires fast analysis, actions and reactions; that is why I always reach a point that I loss concentration, focus and I start making those really stupid mistakes. That is why I created this indicator that helped me to automatically identify these potential entries (based on the formation of candlesticks) instead of doing all the work myself. I know there are plenty of Metatraders who also suffer from this and that is why I would like to share this indicator with you, hopefully it will be beneficial. Do not forget to send you comments as well as rate these scripts. Happy trading!
