TrendSpider

What is TrendSpider?

TrendSpider is an automated technical analysis platform that combines charting, market scanning, backtesting, and an AI market analyst in one browser-based tool. It covers stocks, ETFs, currencies, digital assets, futures, and indices, and reports more than 20,000 customers and coverage across 300,000-plus assets. Rather than manually drawing trendlines or scrolling through charts, traders can automate pattern detection and build, test, and run strategy bots directly on the platform.

Key Features

Automated Technical Analysis

TrendSpider algorithmically detects trendlines, support and resistance zones, and Fibonacci levels, and overlays multiple timeframes on a single chart for faster multi-timeframe analysis.

Market Scanners

Scanners search the market using customizable multi-factor, multi-data, and multi-timeframe conditions, and can be described in plain English, which the platform converts into scan logic — a genuine AI stock scanner experience.

Sidekick AI Market Analyst

Sidekick is TrendSpider's built-in AI trading assistant, powered by Claude by default with optional access to Gemini and ChatGPT on paid tiers. It can see a user's open charts, indicators, and drawings, pull fundamentals, SEC filings, earnings transcripts, options flow, and insider trades, and act on requests such as running a scan or writing a custom indicator.

Custom Indicators and AI Coding Assistant

Users can code indicators in JavaScript or describe the logic in plain language and let the AI Coding Assistant generate it, including a multi-step agentic mode introduced in 2026.

Strategy Bots and Backtesting

TrendSpider supports no-code strategy backtesting with historical data, and can connect to more than 30 supported brokers for automated trade execution.

Who Is TrendSpider For?

Active and swing traders who want automated chart analysis instead of manual drawing, and traders who want to build, backtest, and automate their own strategies rather than relying only on a pre-built signal feed.

Limitations

TrendSpider does not generate a daily list of trade ideas the way a pure signal-scanning tool does; it requires the trader to already have a ticker or scan in mind. Pricing is on the higher side compared to basic charting tools, escalates significantly at higher tiers, and the platform no longer offers a free trial, instead charging a small fee for a time-limited full-access trial. Sidekick's free usage is capped at 25 messages per month, with a separate paid subscription required for heavier AI use
