## About:

 The model was fine-tuned on the LLaMA 7B. [weights_Llama_7b](https://huggingface.co/mrzlab630/weights_Llama_7b)

the model is able to identify trading candles.
the model knows about: 

- Four Price Doji,
- Inverted Hammer,
- Hammer,
- Hanging Man,
- Doji,
- Long-legged doji,
- Dragonfly doji,
- Inverted Doji,
- Bullish,
- Bearish
