Our Take
Portfolio123: Portfolio123 is the most powerful quantitative screening and backtesting platform available to retail investors. Its combination of institutional-grade FactSet data, 20-year point-in-time backtesting, multi-factor ranking systems, and commission-free broker integration creates genuine analytical depth that no consumer alternative matches. The learning curve is steep and the interface is dated, but for systematic investors willing to invest the time, no other platform delivers this level of quantitative rigor at $25-83/month.
Trade Ideas: Trade Ideas is the most powerful AI-driven stock scanner available to retail traders, and Holly AI's self-optimizing strategy engine has no direct competitor. The price is steep — Premium costs more per month than many traders' entire tool stack — but for serious day traders who rely on momentum scanning and want automated execution, the combination of real-time scanning, AI signals, and broker integration delivers value that cheaper alternatives simply cannot replicate.
Pricing Comparison
Portfolio123 Pricing
Portfolio123's pricing is straightforward and competitive for the depth of tooling it provides. The free tier includes broker integration with Tradier and Interactive Brokers, fundamental charting, and a consolidated brokerage account view — useful but limited for research. The Screener plan at $25/month unlocks the full financial database, 460-plus screening metrics, and five years of backtesting data. The Pro plan at $83/month adds 20 years of backtesting, multi-factor ranking systems, rolling screens, position sizing, and API access. Annual billing saves 28% on Retail plans and 23% on Pro plans. A 21-day trial at $19 provides full Pro-level access with 10 years of data and no auto-renewal — a low-risk way to evaluate the platform. For context, Stock Rover Premium Plus costs $28/month with shallower backtesting, while Trade Ideas starts at $118/month for a narrower use case.
Trade Ideas Pricing
Trade Ideas offers three tiers. The free Tester plan provides delayed data with Stock Racing and PiP Charts — useful for exploration but not for live trading. The Standard plan costs one hundred twenty-seven dollars per month or eighty-nine dollars on an annual subscription, saving four hundred fifty-six dollars per year. It includes real-time scanning, paper trading, chart trading, Brokerage Plus integration, and ten on-screen charts. The Premium plan — the tier most reviewers recommend — costs two hundred fifty-four dollars per month or one hundred seventy-eight dollars annually, saving nine hundred twelve dollars per year. Premium adds Holly AI signals, backtesting, automated trading, Smart Risk Levels, twenty-plus curated templates, unlimited watchlists, and twenty on-screen charts. Add-ons like AVWAP and GonoGo range from five to forty-nine dollars per month. Multiple promotional codes circulate — offering ten to fifteen percent off the first year. Compared to competitors, Trade Ideas is the most expensive retail scanner by a wide margin, but it is also the only one offering AI-driven strategy optimization and automated execution in a single platform.
What Users Say
Portfolio123
User sentiment is overwhelmingly positive among those who invest the time to learn the platform. On Trustpilot (4.8/5, 50 reviews), 88% of ratings are five stars — an unusually high concentration. Users describe it as "the best quant platform for retail users" and "simply the best product for quantitative stock analysis." Several long-term members report that Portfolio123 "genuinely changed my life as an investor," citing the shift from intuition-based to systematic, data-driven decision-making. Professional reviewers at GreatWorkLife and LiberatedStockTrader both award 4.1/5, praising screening depth and backtesting power while noting the learning curve. The sole recurring negative theme is the steep onboarding — not the platform's capability or value. One Trustpilot reviewer gave a single star citing community dynamics, but this is an extreme outlier against 49 four- and five-star ratings.
Trade Ideas
User sentiment toward Trade Ideas splits sharply between professional reviewers and general users. Independent blog reviews consistently rate the platform between 4.5 and 4.8 out of 5, praising the scanner depth, Holly AI's signal quality, and the educational ecosystem. A certified financial technician scored it 4.52 out of 5 after lab testing. One long-term subscriber on Trustpilot described it as the "best subscription I got to grow my account," while another with twenty years of use reported near-zero issues. However, Trustpilot's aggregate score sits at 2.3 out of 5, with fifty-four percent of twenty-eight reviews awarding a single star. Common complaints include software instability, outdated graphics, insufficient Holly AI alert volume, billing disputes with automatic renewals exceeding two thousand dollars, and customer support that redirects to YouTube tutorials rather than providing direct assistance. The pattern suggests that traders who invest the time to master the platform find exceptional value, while those expecting a polished, intuitive experience are frequently disappointed.
