TrendSpider

What it is

TrendSpider is a browser-based technical analysis platform whose pitch is that the chart draws itself: trendlines, Fibonacci levels and chart patterns are detected automatically across multiple timeframes rather than dragged by hand. Around that sit a real-time market scanner, a point-and-click backtester, cloud alerts and no-code strategy bots.

The job most people buy it for is scanning — finding setups without writing the screen by hand, then handing the match to an alert or a bot. Charting is the surface you land on; the scanner, the Strategy Tester and the bots are what the tiers actually meter.

Pricing

Four plans, billed monthly at $82, $137, $183 and $321, all with identical features and market data. What differs is capacity, and the number that matters is the timeframe floor: Standard scans and backtests no finer than two-hour bars, Premium five minutes, Enhanced and Advanced one minute. A day trader is on a $183 plan whether the marketing implies it or not.

Annual billing discounts these, and a sale was running on 13 September 2026 advertising up to 45% off the first twelve months — promotional pricing that excludes add-ons and data feeds and is non-refundable. There is no free plan; the trial costs $19 to $49 for 14 days.

Data & coverage

Real-time US equities, ETFs, forex and crypto are included for non-professionals, which is the genuine cost advantage here — most competitors bill exchange fees separately. Futures add $7.50 a month, OPRA options $9.50, and self-certified professionals owe NASDAQ $29. OTC and some index feeds are delayed up to 15 minutes.

The catalogue runs to roughly 61,000 assets: US-listed stocks and ETFs, US options, CME-complex futures, 3,200-plus forex pairs and 28,000 crypto pairs. Backtests reach 50-plus years of history where the symbol has it, but each test is capped by candle count — 2,000 on Standard, 30,000 on Advanced.

Integrations

Alerts and strategy bots post to webhooks, which is how anything leaves the platform. Broker connections run through SignalStack: a free SignalStack account comes with the subscription for manual order entry, and automated execution is capped at five orders a month before you pay SignalStack separately. Custom indicators are written in JavaScript inside the platform.

Limitations

• No public data API. The JavaScript layer builds indicators inside TrendSpider; you cannot pull its data out into your own code. CSV export covers backtest results, the options map and watch lists.
• No non-US listed equities. No LSE, TSX, Euronext or Asian single stocks, at any tier.
• The cheap plan cannot day trade. A two-hour scanning floor on the $82 plan makes it a swing-trading product, and the gap to a one-minute floor is $101 a month.
• Automated execution is a second bill. Five free orders a month, then SignalStack pricing.
• No portfolio tracking or tax reporting. This is an analysis and execution-timing tool, not a record of what you hold.
• Nothing is free. Even evaluating it costs money, and the trial fee does not come back.

Alternatives

TradingView is the obvious comparison and is cheaper, with a free tier and a far larger community script library, but it bills US exchange data separately and its scanner is a screener rather than a live scan. Trade Ideas is the closer rival on real-time scanning and costs more. Traders who want depth and footprint charts on futures are in NinjaTrader or Sierra Chart territory instead.

Compare it against the rest of the charting platforms and screeners.
