Calculations & Plots
Calculations are rebuilt in Pine Script; buffers become plots, and fills and shapes use Pine’s plotting functions. Any visual differences are agreed in advance.
We rewrite MQL5 indicators in Pine Script and turn MT5 Expert Advisors into Pine Script strategies — and tell you upfront what an EA can and can’t do on TradingView.

MT5 to TradingView conversion means rewriting MQL5 code in Pine Script, TradingView’s own language. Indicators carry over well and become TradingView indicators. An Expert Advisor becomes a Pine Script strategy: it runs on TradingView’s chart and in its Strategy Tester and can send alerts, but it doesn’t trade your broker account by itself — so what the EA does is reviewed before work starts.
Indicators carry over well: calculations, plots, alerts and multi-timeframe logic all have Pine Script equivalents. Converting an MT5 indicator to TradingView means rebuilding them in Pine Script, within TradingView’s limits.
Calculations are rebuilt in Pine Script; buffers become plots, and fills and shapes use Pine’s plotting functions. Any visual differences are agreed in advance.
Values from other timeframes and symbols are requested in Pine Script, from the forming bar or from confirmed bars, as the original does.
Alert conditions are built into the script, ready to be added as TradingView alerts in your account.
Lines, labels and boxes become Pine drawings and panels become tables. The agreed information and functions are kept within TradingView’s limits; complex interactive panels may need simplifying, and the look is agreed separately.
MQL5 calculations built on indicator handles and CopyBuffer are rebuilt as direct Pine Script calculations and checked bar by bar.
New settings or functions can be added, several indicators combined into one, or the indicator turned into a strategy.
An MT5 Expert Advisor trades on your broker account; a Pine Script strategy simulates trades on TradingView’s chart. Converting an EA means turning its trading rules into a strategy for backtesting and alerts — not copying everything the EA does. An MT5 EA works with orders, deals and positions on a hedging or netting account; on TradingView these become entries and exits of a single strategy position. Multi-symbol EAs and logic that reacts to trade events are assessed separately.

| Reacting to trade events — fills, closed positions | Yes | PartlyOnly events of the strategy’s simulated orders |

Which parts of your EA carry over is checked before work starts, and anything without a TradingView equivalent is agreed with you. TradingView backtest results won’t match MT5 exactly: the two platforms use different data and model fills differently.
If the strategy’s alerts should trade an MT5 account, they can be executed by our TradingView to MT5 trade copier. It executes the signals but doesn’t restore EA logic that depends on the real balance, actual fills or other positions on the account; whether an alert fires on the trading condition or on the simulated order fill is agreed in advance.
MetaTrader 5 and TradingView run code in different ways. These are the differences that decide whether a converted script behaves like the original — and what we do about each of them.
Your MT5 broker’s prices
The data source selected in TradingView
We take the data difference into account and agree with you how closely values must match.
Indicators and EAs react to new ticks; the exact behaviour depends on the code
Indicators update as the current bar forms; strategies calculate on bar close by default
We agree whether signals act inside the bar or on its close, and check historical and real-time behaviour separately.
Data read directly from any timeframe
Requested from another timeframe, from the forming or the confirmed bar
We keep the original’s behaviour — forming or confirmed values. We also check the original for future-data leakage and agree any corrections before conversion.
Orders, deals and positions; hedging or netting account
Simulated orders, one net position per strategy
We map the EA’s trade logic to strategy orders and agree what changes before work starts.
Chart objects and panels created as needed
Drawings, labels and tables, with limits per script
We keep the agreed information and functions within Pine’s limits; complex interactive panels may be simplified, and the look is agreed with you.
Pop-up, push and email alerts sent by the code
Alerts created in your TradingView account from the script’s conditions
Alert conditions are built into the script, ready to be added as TradingView alerts.
Some things depend on the platform itself: DLLs, file and web access; trading several symbols at once; broker account data; and tick-by-tick history. We point these out before work starts and agree the closest TradingView equivalent with you.
A converter or an AI pass can produce Pine Script quickly. The risk is not the tool but an unchecked result: code can compile and still behave differently from the original, and an EA’s trade logic often has no direct Pine equivalent. We start from how the MT5 version behaves and rebuild it in Pine Script.
| Automatic conversion | Manual conversion at Nordman Algorithms | |
|---|---|---|
| Starting point | Often the MQL syntax, statement by statement | How the MT5 version behaves |
| Platform differences | Often found later, if at all | Identified before work starts and agreed with you |
| EA trade logic | Order functions translated without a Pine equivalent | Mapped to strategy orders, with limits agreed upfront |
Send it to us — we review it and give you a fixed price and timeline before work starts.
We run the MT5 original and the TradingView version on the same instrument and timeframe, with matching trading sessions and bar timestamps, and compare them against acceptance criteria agreed with you:
If something doesn’t match, we find the cause — price data, platform behaviour or the code — and check the result against the agreed specification.

Most MT5 indicators can be rebuilt in Pine Script. Features without a Pine Script equivalent — DLL calls, file access, or more drawings than Pine allows — need a different approach; we tell you about them before work starts.
Not as an EA. Its trading rules become a Pine Script strategy for backtesting and alerts on TradingView. The strategy doesn’t trade your broker account by itself; to trade automatically, its alerts are sent to an execution layer such as our TradingView to MT5 trade copier.
Anything TradingView has no equivalent for: real orders on your broker account, trading several symbols at once, long and short positions held together, broker account data, and DLL, file or web access. Which parts of your EA are affected is checked before work starts.
Not always exactly. Your MT5 broker and the data source selected in TradingView provide different prices, and some things work differently on the two platforms. How closely values must match is agreed before work starts, and any difference is traced to its cause.
Not exactly. The two testers use different data and model fills differently, and some EA logic changes on TradingView. What we check is that entries and exits follow the agreed rules.
Conversion needs the .mq5 source code. Without it, we can assess recreating the indicator or strategy from your description, settings and examples of how it behaves — but an exact match with the original can’t be promised in advance.
No. Our developers write the Pine Script version themselves, based on how the MT5 version behaves.
Yes. Pine Script indicators and strategies can be rewritten in MQL5 — see our TradingView to MT5 conversion page.
It depends on the size of the code, the EA’s trade logic, data from other timeframes or symbols and any features without a Pine Script equivalent. After reviewing your .mq5 code we give you a fixed price and an estimated timeline before work starts.
