ChartMill vs Trade Ideas: Which AI Scanner Wins in 2026

ChartMill is the better pick for traders who want deep fundamental and technical screening at a low monthly cost, while Trade Ideas is the better pick for traders who want the platform to generate AI trade signals and execute trades automatically. The right choice comes down to whether you want a research tool or an automation engine.

Both tools target active stock traders, but they solve different problems. ChartMill, built by a small Belgium-based team, leans into screening logic: you can combine valuation ratios, earnings growth, technical patterns, and candlestick recognition in one scan, then save it as a reusable filter. Trade Ideas, based in the US, built its reputation on real time odds and its AI engine, branded Holly since 2018, that scans the entire market during the session and pushes out ranked trade ideas with entry, target, and stop levels. If you already know what setup you are looking for and want to screen for it cheaply, ChartMill fits. If you want a tool that finds setups for you and can place the trade through a connected broker, Trade Ideas fits, at a materially higher price. The sections below break down the numbers so you are not guessing which one is worth the monthly bill.

Is ChartMill or Trade Ideas better for stock scanning?

ChartMill is better for scanning by fundamentals and building custom multi-factor filters at a low price. Trade Ideas is better for real time technical scanning backed by an AI engine that ranks opportunities across the whole market during market hours. Traders who value screening flexibility and price choose ChartMill; traders who value speed and automated signal generation choose Trade Ideas.

ChartMill's scan builder lets you stack more than 100 fundamental and technical conditions, from price to earnings ratio and revenue growth to RSI and moving average crossovers, then backtest the resulting filter against historical data going back to 2007. Trade Ideas skips fundamentals almost entirely and instead runs its Holly AI engine continuously through the trading session, surfacing signals ranked by a live win-rate score calculated from thousands of simulated trades per second.

For a swing trader who screens once a night, ChartMill's static scan builder is enough and considerably cheaper. For a day trader who needs the scanner running live and flagging setups in real time without babysitting the screen, Trade Ideas' always-on AI engine is the better fit, and that speed is what its higher price pays for. Trade Ideas' Holly AI engine runs continuous scans through the session and assigns each signal a live win-rate score, a level of real time automation ChartMill's static scan builder does not attempt to match.

How much do ChartMill and Trade Ideas cost in 2026?

Pricing is where the two platforms diverge the most. ChartMill's most expensive annual plan, at $299.97 a year, costs less than one month of Trade Ideas Premium billed monthly ($254). Trade Ideas does offer a lower entry point through its Standard tier at $89/month annually, but that plan does not include the AI signal engine that is the platform's main selling point, you need Premium for that.

Both platforms discount for annual billing: ChartMill saves you 29% versus its monthly rate, and Trade Ideas Standard saves $456/year, about 30%, versus its monthly rate. Neither publishes a persistent free tier for the paid scan features, though ChartMill lets you sample individual scans before subscribing. A full year of Trade Ideas Premium, at $2,136, costs more than seven years of ChartMill's cheapest annual plan.

Framed differently, ChartMill's annual plan costs about $0.82 a day. Trade Ideas Standard's annual plan costs about $2.93 a day, and Premium's annual plan costs about $5.85 a day. For a full time trader treating the software as a business expense, that Premium price is a small fraction of a single winning trade; for a part time trader running one account, it is a much bigger bite out of monthly returns.

What features do you get with each platform?

ChartMill

Trade Ideas

Feature for feature, ChartMill covers more ground on fundamentals and Trade Ideas covers more ground on automation. Neither platform does both well, so the choice comes down to which side of that split matches how you actually trade. Traders who screen for value or earnings setups get more mileage from ChartMill's filters than from anything in Trade Ideas' toolkit.

Both vendors make it easy to change your mind after signing up. ChartMill lets you upgrade from its monthly plan to the discounted annual plan at any time, so trying it at $13.97 for the first month carries little risk beyond that first charge. Trade Ideas describes both its Standard and Premium monthly plans as flexible billing with straightforward cancellation, useful if you want to test Holly AI for a single earnings season before committing to an annual contract.

Many ChartMill users pair it with a separate charting platform for order entry and alerts, since ChartMill itself is a screener rather than a full charting suite. Trade Ideas, by contrast, includes its own charting and order entry, so Premium subscribers rarely need a second charting subscription on top of the $178 to $254 monthly cost.

How do the AI signals and automation compare?

Trade Ideas' Holly AI has run since 2018 and re-trains its strategies each week against the prior week's market data, then trades a simulated $100,000 account live so you can watch its picks perform before following them with real money. ChartMill has no equivalent AI signal generator. Its closest feature is a set of pre-built scan templates, breakouts, oversold bounces, earnings gaps, that you run manually rather than an engine that flags trades for you continuously.

Because ChartMill has no signal-generation AI to benchmark, the honest comparison is Trade Ideas' Holly against itself: Trade Ideas reports Holly's simulated $100,000 account results publicly on its site as a transparency measure, which is the only apples to apples automation data either platform provides.

Trade Ideas publishes Holly's live results to Premium subscribers throughout market hours, so you can see a strategy's running performance before committing real capital to it. ChartMill's equivalent transparency feature is the historical backtest report attached to each saved scan, which shows how a strategy would have performed since 2007 rather than a live, continuously updated score.

Who should choose ChartMill vs Trade Ideas?

• You screen for value or earnings-driven setups, not just technicals
• You want unlimited scans for under $35/month
• You are comfortable acting on signals manually
• You want backtesting without paying for automation you will not use

• You day trade and need live scanning through the session
• You want AI-ranked signals with entry, target, and stop levels
• You plan to use automated execution through a connected broker
• A budget of $89 to $254 a month is not a dealbreaker

Cost is the deciding factor for most traders switching between the two. At ChartMill's price, you can afford to run it alongside a separate charting platform; at Trade Ideas Premium's price, the scanner needs to be your primary tool to justify the bill. That gap alone settles the decision for most budgets before features even enter the conversation.

The verdict

ChartMill is the stronger buy for swing and value traders who want a serious screening tool without a serious price tag. At $25 to $35 a month, it pays for itself if it helps you find even one or two extra trades a quarter, and its fundamental plus technical scan builder is deeper than anything at a comparable price point. Trade Ideas is the stronger buy for active day traders who need the market scanned continuously and are willing to pay $89 to $254 a month for an AI engine that does that scanning and, on the Premium tier, the execution too.

Neither tool replaces the other; they solve different problems. If you are deciding between them on budget alone, start with ChartMill, since Trade Ideas' AI signals only live behind the Premium tier at $178 to $254 a month. If you are deciding based on how you trade, day traders who need live automation should pay for Trade Ideas, and everyone else will get more value per dollar from ChartMill. For most traders, ChartMill's $25 to $35 a month buys more screening depth per dollar than Trade Ideas' $89 to $254 a month buys in automation, unless live AI-driven execution is specifically what you need.
