If you trade CFDs or forex, you will almost certainly come across two platforms: TradingView and MetaTrader (MT4 and MT5). Both can run custom indicators, both are widely used, and many traders end up using both. But they are built for different jobs, and an indicator written for one will not run on the other. This guide explains the practical differences so you can decide where your indicators should live.
The short version
- TradingView is primarily a charting and analysis platform. It runs in the browser, on desktop and on mobile, and its indicators are written in Pine Script.
- MetaTrader 4 and 5 are trading platforms supplied by brokers. You connect to your broker's server, see your broker's prices and place trades directly. Indicators and Expert Advisors (EAs) are written in MQL4 (MT4) or MQL5 (MT5).
If you mainly analyse charts and place trades elsewhere, TradingView is often the natural home for an indicator. If you want to automate trading or see signals on the exact price feed you execute on, MetaTrader is usually the better fit.
Charting and ease of use
TradingView is known for its clean, fast charts, drawing tools and the ability to open the same layout on any device after logging in. Adding an indicator is straightforward, and you can keep multiple chart layouts and watchlists in your account.
MetaTrader's charts are more basic visually but very functional. Templates, profiles and indicators are stored locally in the terminal's data folder, which means your setup lives on the computer (or VPS) where MetaTrader is installed. MT5 adds more timeframes than MT4, a built-in economic calendar and depth-of-market for brokers that provide it.
Price data: the detail many traders miss
CFD prices are not identical across providers. Each broker builds its own quotes, spreads and trading hours, and TradingView may show a different data feed from the one your broker uses — depending on which symbol you load. On gold (XAUUSD) or indices, that can mean slightly different highs, lows and closing prices.
For most chart analysis this does not matter much. But if an indicator draws precise levels or triggers on a candle close, those levels can differ by a few points between platforms. If precision matters to your rules, use your broker's own symbol on TradingView where available, or run the indicator in MetaTrader on the same feed you trade.
Automation: indicators vs Expert Advisors
An indicator calculates and displays information — lines, boxes, arrows, alerts. You still decide and place the trade. An Expert Advisor is a program that runs inside MetaTrader and can open, manage and close trades automatically according to its rules.
- On MetaTrader, automation is built in. An EA runs while the terminal is open and connected, which is why many traders run MT4/MT5 on a VPS. EAs can be tested in the built-in Strategy Tester before use on a demo account.
- On TradingView, Pine Script strategies can be backtested on the chart, and indicators can fire alerts. Executing trades from TradingView depends on broker integrations or third-party tools, and some alert features (such as webhooks) are limited to paid plans — check TradingView's current plan comparison.
If fully automated execution is the goal, MetaTrader with an Expert Advisor for MT4/MT5 is the more direct route.
Pine Script vs MQL4/MQL5
Pine Script is designed specifically for chart calculations, so short indicators can be written compactly and they recalculate as each bar updates. MQL4 and MQL5 are C-like languages with access to the terminal, account information and order functions, which is what makes EAs possible.
The practical consequences:
- An indicator is not portable. A Pine Script indicator must be rewritten in MQL to run on MetaTrader, and vice versa.
- MT4 and MT5 are not interchangeable either. An .ex4 file runs only on MT4 and an .ex5 file only on MT5; MQL4 code usually needs changes before it compiles in MQL5.
- Logic can be matched, but output can differ slightly because of the price-feed and bar-timing differences described above.
Cost and access
MetaTrader is generally provided free by brokers that offer it; you need an account with such a broker (a demo account is enough to test indicators). TradingView has a free plan and several paid plans; paid plans raise limits such as indicators per chart, active alerts and saved layouts. Plan details change, so check TradingView's own pricing page.
A Pine Script indicator delivered as a source file works on any TradingView plan, including free: you paste it into the Pine Editor in your own account, save it and click "Add to chart". That is how our TradingView chart indicator is delivered — by email with setup instructions, typically within 24 hours of payment confirmation.
Which should you use?
Choose a TradingView indicator if…
- You do most of your analysis on TradingView and want the same charts on your laptop, phone and tablet.
- You trade manually and want visual signals or levels to support your own decisions.
- Your broker does not offer MetaTrader, or you trade through several brokers.
Choose an MT4/MT5 indicator if…
- You execute on MetaTrader and want signals calculated on your broker's exact prices.
- You may want to automate the same logic as an EA later.
- You prefer a locally installed tool that does not depend on a web account.
Our MT4/MT5 chart indicator is delivered as an installable .ex4/.ex5 file with installation instructions.
Or use both
Many traders analyse on TradingView and execute on MetaTrader. If that is you, the Indicator Duo Bundle (TradingView + MT4/MT5) gives you both ready-built indicators in one order. If you have your own rules in mind, the customized indicator service builds to your specification on the platform you choose, with the scope and quote confirmed before work begins.
Checklist before you buy or build any indicator
- Which platform do you execute on, and which do you analyse on?
- Does the indicator need your broker's exact prices, or is approximate charting enough?
- Do you need alerts, and are they available on your plan?
- Will you want to automate it later? If so, MQL is the path.
- Test any new tool on a demo account first and read exactly how it calculates its output.
