Our Take
Thinkorswim: Thinkorswim is the most powerful free trading platform available — 400+ indicators, professional-grade options analysis, ThinkScript customization, and integrated brokerage execution with $0 stock commissions, all without a subscription fee. Its biggest weaknesses are a steep learning curve, a dated interface, and post-Schwab acquisition stability issues reflected in a 1.3 Trustpilot score. We recommend it for active options traders, technical analysts, and futures traders who want institutional-grade tools at zero platform cost and are willing to invest the time to master a complex interface. Start with paperMoney to learn the platform risk-free before committing real capital.
TrendSpider: TrendSpider is the strongest option for traders who want AI and automation to handle the mechanical side of technical analysis. Its automated trendlines, no-code backtesting, and multi-timeframe overlays are genuinely best-in-class. The trade-off is premium pricing and a real learning curve — but for swing traders and systematic analysts willing to invest in both, the time savings and analytical rigor justify the cost.
Pricing Comparison
Thinkorswim Pricing
Thinkorswim's pricing model is straightforward and genuinely differentiated: the platform itself is free. There is no subscription fee, no tiered plan structure, and no minimum account balance requirement. You pay only per-trade commissions on derivatives — $0.65 per options contract, $2.25 per futures contract plus exchange fees, and spread-based pricing on forex. Stocks and ETFs trade at $0 commission. A cash account requires no minimum deposit; margin accounts require $2,000. There are no inactivity fees. The competitive context makes this pricing remarkable. TradingView's Essential plan costs $14.95 per month and still limits you to two charts and five indicators per chart. TradingView Premium runs $59.95 per month. NinjaTrader's lifetime license is $1,099. Trade Ideas starts at over $100 per month. Thinkorswim delivers 400+ indicators, 32 simultaneous charts, options analysis with real-time Greeks, backtesting, scanning, and paperMoney simulation — all at zero platform cost. The catch is that options commissions at $0.65 per contract sit above some discount competitors. Webull offers $0 options commissions. Tastytrade caps options commissions at $10 per leg. For high-volume options traders, these per-contract savings can add up. Futures at $2.25 per contract are within the standard range. For most traders, however, the zero platform fee far outweighs any per-trade commission difference.
TrendSpider Pricing
TrendSpider offers four tiers: Standard ($89/month), Premium ($149/month), Enhanced ($199/month), and Advanced ($349/month). Annual billing reduces costs by roughly 33%. All plans include full platform access, 300+ indicators, backtesting, AI Strategy Lab, trading bots, Sidekick AI, and real-time data for equities, forex, and crypto. Tiers differ primarily in workspace count, bot limits, alert duration, and training sessions. Optional add-ons include real-time futures data ($7.50/month) and enhanced backtest depth ($39/month). There is no free tier; the 14-day trial requires upfront payment. TrendSpider runs aggressive seasonal sales — up to 70% off annual plans during Black Friday and holidays. Compared to TradingView ($33.95/month entry) and MetaTrader (free), TrendSpider sits at the premium end of the market.
What Users Say
Thinkorswim
User sentiment toward thinkorswim diverges sharply depending on the review platform and the era of usage. Editorial reviews are consistently strong: BullishBears rates it 4.6/5, Brokerage-Review.com gives 4.5/5, and TopRatedFirms awards 4.5/5. TrustRadius users rate it 9.0/10 with a likelihood-to-recommend score of 9.3/10 — one reviewer called it "a class of its own" while another praised the ability to "test out investment strategies without the risk of losing real money." The praise centers on feature depth, charting quality, and the zero-cost value proposition. Trustpilot tells a different story. The platform holds a 1.3 TrustScore from approximately 46 reviews, with 83% being one-star. One reviewer wrote, "We call it Think and Sink." Another described it as "completely unintuitive, ugly, too long of a learning curve." The critical distinction is timing: the majority of negative reviews emerged after Schwab's acquisition of TD Ameritrade, and they focus on platform stability, execution quality, and login issues rather than feature gaps. The pattern is clear — the tool's capabilities remain respected; the operational transition has introduced real friction that Schwab has not fully resolved.
TrendSpider
User sentiment across 650+ Trustpilot reviews (4.7/5) and multiple review platforms skews strongly positive. The most consistent praise targets customer support — one Trustpilot reviewer called it "the only thing more impressive than the tool itself." Automated trendline detection and backtesting draw frequent commendation, with one reviewer describing TrendSpider as "a breath of fresh air — straightforward and packed with integrated features." Criticism centers on pricing — one user called it "extremely high for not being able to do anything sophisticated" — and scanner limitations, with another noting the scanner "doesn't auto-refresh." The learning curve appears in roughly one-third of reviews, though most frame it as a temporary hurdle rather than a dealbreaker. Across professional review sites, scores range from 4.0 to 4.8 out of 5.
