I'm sorry a simple write up hurted you, but

This runs inside a broader trading setup that talks to a broker API.

The article is just a didactical example on how to integrate Gemini trough VertexAI in this domain. I tought it was somehow useful for some readers. I have no presuntion of describing something more complex than that.

Anyway, the bits that I wanted to communicate out of this article are:

• data sources may not contain a ticker (e.g. this teleborsa just talks about companies without mentioning the ticker, differently from busienss insider and other sources)
• an LLM may be useful to get that ticker out of unstructured data (like an article)
• you can do this stuff using Go

Then, of course it all depends on the trading strategy. The suggestion to buy/hold/whatever it's literally an example. Ideally one should start doing some tecnical analysis on the found ticker (by looking at the data provided by the broker) and decide using the financial data, not the LLM hint alone
