TrendSpider is a charting and analysis platform that automates chart work that traders usually do by eye. It detects trendlines, Fibonacci levels, and candlestick patterns across multiple timeframes, so you spend less time drawing and more time deciding.
Beyond charts, it offers scanners to search for setups across markets and backtesting to test a strategy against historical data. Machine learning and language-model features help with building strategies and writing the code behind them. It covers stocks, ETFs, currencies, crypto, futures, and indices.
TrendSpider is an analysis tool, not a brokerage, so you place trades elsewhere. It is a paid product with a real learning curve because of how many tools it includes. Traders who want hands-off automation of charting will get the most from it, and casual investors may find it more than they need.
