FAQ

TrendeLiner is an AI-powered platform that helps traders build custom trading indicators without needing to code. Describe what you want, configure parameters, and our AI generates professional ready-to-use code in PineScript (TradingView), Python, or JavaScript.

No coding experience required. TrendeLiner is designed for all traders. Use Guided Mode with simple menus, or Free Mode to describe your indicator in plain English and let the AI write the code.

1. Create a free account
2. Choose Guided Mode or Free Mode
3. Select output language (PineScript, Python, or JavaScript)
4. Click "Generate Indicator with AI"
5. Copy the code and paste it into TradingView or your platform

Guided Mode — Use structured menus to configure your indicator: base indicator (RSI, MACD, EMA...), market, timeframes, entry signals, risk management, and alerts.

Free Mode — Write your idea in natural language. Example: "RSI with divergence — buy signal when price makes new low but RSI does not, with 70/30 alerts".

TrendeLiner generates code in 5 languages across all major trading platforms:

PineScript v6 — For TradingView (most popular for charting)
MQL5 — For MetaTrader 5, the world's most used Forex/CFD trading platform
MQL4 — For MetaTrader 4, still widely used by millions of traders worldwide
Python — Using pandas-ta, for backtesting and algorithmic trading
JavaScript — Using technicalindicators npm, for web-based trading apps

Indicators can be optimised for: Forex, Crypto, Stocks, Futures, Indices, and Commodities. The AI adapts parameters and logic based on your selected market.

Multi-timeframe analysis across: 1m, 5m, 15m, 30m, 1h, 4h, and 1D. Select multiple timeframes and the generated PineScript uses request.security() to analyse all of them simultaneously.

Use the Fix Errors section below the generated code. Copy the error from TradingView, paste it in the error box, and click "Fix with AI". The AI will correct the code automatically. Repeat until all errors are resolved.

1. Generate your indicator and click COPY
2. Open TradingView → Pine Script Editor (bottom of chart)
3. Delete existing code and paste
4. Click Add to chart
The indicator appears on your chart immediately.

All TrendeLiner PineScript code includes //@version=6 as the first line. Always use the COPY button in TrendeLiner to copy the full code correctly.

1. Generate your indicator in TrendeLiner, select MQL5 and click COPY
2. Open MetaTrader 5 → Tools → MetaQuotes Language Editor (or press F4)
3. Click New → Custom Indicator → give it a name
4. Delete the template code and paste your copied code
5. Press F7 to compile (or click the Compile button, or go to File → Compile)
6. Check the Errors tab at the bottom — if it shows 0 errors, 0 warnings ✅ the .ex5 file was created automatically
7. Back in MT5, open the Navigator (Ctrl+N) → right-click Indicators → click Refresh
8. Your indicator will appear — drag it onto the chart to use it

1. Generate your indicator in TrendeLiner, select MQL4 and click COPY

TrendeLiner generates the .mq4 source code — this is the editable code you can open and read in MetaEditor.

The .ex4 is the compiled (executable) version that MetaTrader 4 actually runs. It is generated automatically by MetaEditor when you compile your .mq4 file by pressing F7.

You do not need to do anything special — just compile in MetaEditor and the .ex4 is created in the same folder automatically. The same applies to MQL5: .mq5 → compile → .ex5.

MQL4 — Used in MetaTrader 4, the older but still very popular platform. Simpler syntax, great for Forex traders. Uses init() and start() functions.

MQL5 — Used in MetaTrader 5, the newer and more powerful platform. Supports more asset classes (stocks, futures, commodities). Uses OnInit() and OnCalculate() functions. Recommended for new projects.

If you are not sure which to use, choose MQL5 unless your broker specifically requires MT4.

Copy the exact error message from the MetaEditor (shown in the Errors tab at the bottom), paste it into the Fix Errors section in TrendeLiner, and click "Fix with AI". The AI understands MQL4/MQL5 errors and will correct the code automatically.

The Script Converter is a PRO feature that lets you convert trading indicator code between any of the 5 supported languages. For example, you can convert a TradingView PineScript indicator to MQL4 for MetaTrader 4, or convert an MQL5 indicator to PineScript. The AI preserves the exact trading logic while adapting the syntax for the target platform.

You can convert between any combination of the 5 languages:

• PineScript ↔ MQL5 or MQL4
• MQL4 ↔ MQL5
• Any language → Python or JavaScript

The most popular conversions are PineScript → MQL4/MQL5 (for traders who find indicators on TradingView and want to use them on MetaTrader) and MQL4 → MQL5 (for traders upgrading their platform).

Use the Fix Conversion Errors section in the Converter tab. Copy the error message from your platform, paste it in the error box, and click "Fix with AI". The AI will analyse the error in context of the converted code and fix it automatically.

The Script Converter is available exclusively on the PRO plan. Trial and Essential plan users have access to the indicator generator and error fixer, but not the converter.

The Trial plan (15 days free) includes 3 indicator generations per month, all output languages, 30-day history, and access to both Guided and Free modes. Perfect for trying the platform before upgrading.
