If you're looking for a quality free technical analysis tool, I'd recommend checking out TradingView. It's quite popular in the trading community for its user-friendly interface and extensive range of indicators and charting tools. The free version offers a good selection of features, and you can create and save custom analysis. One of the highlights is the social aspect, where you can follow other traders and see their analysis, which can be educational.
Another option to consider is MetaTrader 4 (MT4). While it's more traditionally used for forex trading, it's quite robust in terms of technical analysis capabilities, and many brokers offer it for free. There are also numerous free indicators available within the MT4 community.
Both platforms have strong community support, which can be helpful as you learn. Keep in mind that while these tools are great for analysis, backtesting features can be more limited in the free versions, so you might need to consider that as you advance.
Lastly, remember to always validate findings from technical analysis by considering broader market conditions and fundamentals. Happy trading!
