Stock Charting Platforms & Screeners

The platform fee is not the bill. Exchange data is billed separately and on top of every subscription here, and for an active trader it is frequently the larger number — so price the tools on what your symbols cost to watch, not on the tier name. The second thing that decides the choice is which of five jobs you are buying, because a product built around one of them is usually mediocre at the others.

• Charting, alerts and the largest community — TradingView.
• Screening on fundamentals, for investors — Stock Rover or Finviz Elite.
• Real-time intraday scanning — Trade Ideas or TrendSpider.
• Trading futures from the chart — Sierra Chart, NinjaTrader or Quantower.
• Reading the order book — Bookmap.
• Macro, fundamentals and a research dashboard — Koyfin.

Five jobs wearing one word

Everything in this category draws a chart, and that is close to the last thing these tools have in common. The five jobs below are bought by different people for different reasons, and a product built around one of them is usually mediocre at the others — which is why a price comparison across jobs tells you nothing.

Charting is the analysis surface: drawing tools, indicator library, multi-chart layouts, how far back the intraday history goes, and whether your marked-up charts survive a change of machine. Bought by people who make the decision themselves and want somewhere to think.

Screening is one question asked of the whole universe, once — profitable, under 15 times earnings, above the 200-day. You press run and read a list. It is a research act, usually end-of-day, and it leans on fundamentals at least as much as on price.

Scanning is the same question asked continuously of a live feed, answered by interrupting you. It only means anything intraday, it needs real-time data for every symbol at once rather than for the one on screen, and that requirement is most of why the scanning tools cost several times what the screening tools cost.

Execution is trading from the chart. It is settled by a broker list, not by a feature list: the platform is a client, your broker decides whether it can connect, and on the futures side the broker usually bills the data too.

Orderflow is reading the book instead of the bar — footprint, DOM, heatmap, market-by-order. It is a data problem before it is a software problem, and it is very nearly a futures-only pursuit, for the reason in the FAQ below.

What actually decides the choice

The subscription is not the bill. Platform fee and exchange data are separate purchases, and for an active trader the data can be the larger one. TradingView's US stock bundle is $9.95 a month on top of a paid plan; CME futures data runs about $4 to $5 per exchange for top-of-book and $16 to $17 for depth, or $12 to $15 and $45 to $48 for all four. The spread is real: the platform or broker sets the pass-through, so the same exchange costs different money depending on who bills you. Price the tools on what your symbols cost to watch, not on the tier name.

Professional status is not a judgement about you. It is an exchange classification: are you registered, trading for a firm, using the data in a business, or handling anyone else's money. Non-professional CME top-of-book is $4 to $5 a month per exchange; the professional rate for the same feed is $140 to $156. Every platform makes you self-certify, so getting it wrong is a back-billing exposure rather than a discount.

"Screener" and "scanner" mean whatever the marketing page needs them to. A screener evaluates a stored snapshot; a scanner evaluates a stream and pushes. A screener with a refresh button will not tell you that something is happening right now, and a real-time scanner is wasted money if what you want is twelve candidates to research on Sunday. Check whether the alerts are server-side too — an alert that only fires while the tab is open is a different product from one that fires while you sleep.

Depth history cannot be bought after the fact. Bars backfill; the order book does not. Most platforms record depth and time-and-sales only while you are connected and subscribed, so replaying last March's session needs you to have been subscribed last March. If you intend to study order flow rather than watch it live, ask whether historical depth is sold at all before you plan around it.

The strategy language is the lock-in, not the fee. Pine Script on TradingView, NinjaScript in C# on NinjaTrader, ACSIL in C++ on Sierra Chart, Java on MotiveWave, EasyLanguage on MultiCharts. None of them port, and none of the vendors pretend otherwise. Six months of your own indicators and scans are worth far more than any monthly price difference, which is why people stay for years on platforms they complain about daily. Choose the language with more care than the chart.

Free tiers here are limited by counts, not by quality. The charts on free plans are good. What runs out is saved layouts, indicators per chart, symbols in a watchlist, scan results returned and — nearly always the binding constraint — the number of alerts you may keep active. Work out which of those counts you will hit before you compare monthly prices, because that is the number that decides which tier you actually end up on.

Where this category connects

A platform subscription and a data subscription are two purchases, and the second one is priced in market data APIs — worth reading if you are paying for a feed twice. If what you want is a strategy tested properly rather than drawn on a chart, that is backtesting frameworks, and if it is the record of what you already traded, trading journals.
