Public service announcement.

Technical trading is the equivalent of using astrology for investments. It is not a science and has been roundly refuted as junk for well over 25 years. If you are thinking about actively trading or, worse, "technical analysis", by definition that strongly suggests you are either: 1) not well versed in investing and should spend some time reading the most publicly recommended tomes on investing; 2) believe in astrology; or 3) selling books or services related to technical trading which is the only way to make money off it it.

I don't believe using Hacker News to advertise a commercial product relating to technical analysis is appropriate.

Technical analysis is very real. The fact that it's abused by scammers mostly targeting retail doesn't make it astrology. I don't disagree with your third point though since most of the TA stuff is available freely online.

I believe active traders find value in combining both fundamental and technical analysis to make their decisions. I am not trying to start on debate on technical analysis but I think a lot of people are using it, and prices are most likely influenced by people's actions.

This demo focuses on technical analysis but it's just a MVP, and the technical analysis part was the easiest to implement, and I'm trying to validate the UX. The full version of the app will allow users to define strategies that incorporate both technical and fundamental factors.

Thank you for sharing your thoughts.

Technical indicators are the bread and butter of professional traders.

Of which the vast majority cannot consistently beat index funds.

Someone suggested adding a comparison to the backtest results, showing the profit and loss from buying and holding the asset versus the profit and loss from the user-defined strategy. I think this is really interesting to see.

Unfortunately, I don't have data on the performance of professional traders, so I can't say whether most of them beat index funds. If you have any sources, I would love to see them.

Clearly their tools are not good enough. /s

Prices are made by humans, including the edge case of automation where instructions are still human.

On average not beating an average where there are transaction and membership fees is therefore expected, it could not be any other way. That doesn't however make the index the best predictor of itself.
