How to build Technical Analyst AI Agent using LLM Vision (no-code with n8n)!

[@delphiguy23]

Hi, Im quite interested with what you have here. I've installed n8n on my local network via docker and trying it out now. I even purchased your template. Question, should the AI be Claude? or can I change that to DeepSeek since its cheaper ;) thanks

[@derekcheungsa]

Thanks for buying the template. Unfortunately, Deepseek doesn't yet support multi-modal, so that LLM can't be used. In my evaluation of the LLM's for this use case, I found Claude Sonnet to be the best. I have also seen good results with gpt-4o which is slightly cheaper than Sonnet. I don't recommend weaker models like gpt4o-mini as the results are not as good.

Thanks for the n8n template 👌 Found you via the marketplace

[@derekcheungsa]

Cool. Please let me know if you have any feedback

Hello! are you using a API pay version for claude? thanks

[@derekcheungsa]

Yes, it is

[@tiinif]

hello!! thanks a lot for this video. It is my first time using n8n. Do you know if I can set Claude anthropic API without a pay version? or are you using a premium version? Thanks!!

[@derekcheungsa]

Thanks! You can use claude.ai for prompt engineering for free. But the API is a paid API.

Can you share the n8n workflow please?

[@derekcheungsa]

Yup, it's now published in the n8n template store

Hey, this is great but im getting an error at the chart-img node with 'Problem in node 'Tradingview Chart' your request is invalid or could not be processed by the service' Ive changed the credentials to use: Name= Authorization, Value=Bearer {MY_API_KEY} I cant figure out where the issue is, any ideas? when i test the step i get error code 422 'must be a valid tradingview EXCHANGE:SYMBOL'

[@derekcheungsa]

Thanks for your feedback. Have you updated settings node to specify which exchange the ticker is in? By default it uses NYSE

[@fangtastical]

@@derekcheungsa Hi Thanks for your reply, i did look at changing the the exchange, but other than overwriting the variable wasnt sure how. instead I looked for the apple symbol on nyse as a known attribute AAPL and used that as i felt it should have a fair chance of success out of the box when i run 'test workflow' it fails on tradingview node, thinking about it I guess this could be expected since no symbol has been input, however when i run as a chat, it fails on 'technical analysis' node with response in chat of 'im unable to do this due to system error, the tool i use is currently unavailable' does the workflow ID need to be changed in the technical analysis node? when i open the node it says 'workflow does not exist' so i chenged it to the ID in the browser, after this it still fails but says invalid symbol FYI im running 1.68.1 via 'self-hosted-AI-starter kit'

[@fangtastical]

@@derekcheungsa I used AAPL as its known on NYSE and i felt should be a good bet. I also realised that this error was generated when I ran the 'test workflow' button, however when i run on chat it failed on the technical analysis node. it complained that the workflow ID was incorrect so I changed that to match the ID in my browser, the same node then fails with invalid symbol FYI I am using 1.68.1 using the 'self-hosted AI starter kit'

[@derekcheungsa]

I'm glad you figured out the id in the url. I'll update the workflow so that it gets that automatically. When you look at the execution logs, does it give you any error messages ?

[@derekcheungsa]

Oh, one thing to try is to make sure you specify ticker symbol without $. For example AAPL and not $AAPL

[@stevensexton5801]

I can't seem to get the tradingview chart API to work.

[@derekcheungsa]

Hi Steven, thanks for your feedback. One common issue is selecting a ticker that is not on the NYSE. This is the default. If the ticker is on another exchange supported by tradingview, you can update the settings node to change to that exchange.

[@giladbar-ilan1472]

@@derekcheungsa so this works only with NYSE or if selecting NVDA for example i will need to also set the exahnge?

[@derekcheungsa]

Yup, it works on all exchanges trading view supports. Just update settings node with exchange. For example, nasdaq

[@derekcheungsa]

Yes it will

[@derekcheungsa]

Leandro, this has been added to the course as well as the template. As for the screen, it's in the latest version of n8n

[@LeandroRosa]

@@derekcheungsa great teacher, hope it gets in the course soon! just looked and its not there, or do you have more than one course? if so, send the link so I can buy the other!! thanks a lot for all teachings

Hi Leandro, it's now published along with the template :-) Thanks for your support.
