TRENDMAP NINJA gives you a quick, organized look at any chart, so you can sharpen your own thinking before you act on it.

About points Each analysis uses a few points. If you run out, you can earn more by watching short rewarded videos, at your own pace. What TRENDMAP NINJA is not TRENDMAP NINJA is an educational and informational tool. It is not financial advice, investment advice, a trading signal service, or a recommendation to buy or sell anything. The AI describes what can be read from the uploaded chart image — it does not predict future price movement, and it does not tell you what to do. Any decision you make about trading or investing is entirely your own, made at your own discretion and risk. Past or current chart shape does not guarantee anything about future prices.
