Introducing Custom Pine Script Indicators on TradesViz Charts Beta

We're excited to announce a new beta feature that allows you to add your own custom TradingView Pine Script indicators directly to TradesViz charts! This feature enables traders to bring their favorite custom indicators from TradingView and use them alongside their trade analysis.

Since we first introduced interactive TradingView charts in 2021, we've continuously added features and enhancements to improve how traders use charts for journaling. Based on user feedback, we integrated TradingView charts into the unified trade view tab, allowing you to review dozens of trades on a single page. To this day, no other journal offers as deep an integration with TradingView as TradesViz. We then introduced the popular chart trades view - a single chart displaying all your trades across an extended date range. The next major feature request came from active TradingView users who wanted to use their own chart templates. The closest solution was our chart templates feature (introduced in 2023), which lets you save and reuse TradingView's built-in indicators as a template.

Now we're taking it a step further. While we still can't support 100% of the indicators available on TradingView's main website, you can now create simpler versions of them using Pine Script - right here within TradesViz and use them across all TradingView charts in your dashboard.

What is This Feature?

TradesViz now includes a built-in Pine Script transpiler that converts TradingView Pine Script code into JavaScript that can run natively in our charting library. This means you can copy Pine Script code from TradingView and add it as a custom indicator on your TradesViz charts.

How It Works

  1. Visit your account settings: www.tradesviz.com/accounts/settings/
  2. Click on "Manage Indicators" under the Chart settings section
  3. Click "Create New"
  4. Paste your Pine Script code
  5. Enter the indicator name and optionally the description 
  6. Click on "Test Code"
  7. If you see a green checkmark at the bottom of the code, save the code by clicking on "Save Indicator"
  8. You can now add the indicator to your charts

Result:

Note: If you do not see a green checkmark when you test the code [OR] if you see the green checkmark and still don't see the indicator in your tradingview chart when the custom indicator is selected, please read the rest of the blog below.

Example: Working Indicators

Here are examples of indicators that work well with the transpiler:

Example 1: Simple RSI with Overbought/Oversold Levels

//@version=6
indicator("RSI Indicator", overlay=false)
length = input.int(14, title="RSI Length", minval=1)
overbought = input.int(70, title="Overbought Level")
oversold = input.int(30, title="Oversold Level")
rsiValue = ta.rsi(close, length)
plot(rsiValue, title="RSI", color=color.blue, linewidth=2)
hline(overbought, "Overbought", color=color.red)
hline(oversold, "Oversold", color=color.green)
hline(50, "Middle", color=color.gray)

Example 2: SuperTrend Indicator

//@version=6
indicator("SuperTrend", overlay=true)
atrLength = input.int(10, title="ATR Length")
factor = input.float(3.0, title="Factor")
[supertrend, direction] = ta.supertrend(factor, atrLength)
plot(direction < 0 ? supertrend : na, title="Up Trend", color=color.green, linewidth=2)
plot(direction > 0 ? supertrend : na, title="Down Trend", color=color.red, linewidth=2)

Example 3: Dual Moving Average Crossover

//@version=6
indicator("MA Crossover", overlay=true)
fastLength = input.int(9, title="Fast MA Length")
slowLength = input.int(21, title="Slow MA Length")
fastMA = ta.ema(close, fastLength)
slowMA = ta.ema(close, slowLength)
plot(fastMA, title="Fast MA", color=color.blue)
plot(slowMA, title="Slow MA", color=color.red)
buySignal = ta.crossover(fastMA, slowMA)
sellSignal = ta.crossunder(fastMA, slowMA)
plotshape(buySignal, title="Buy", style=shape.triangleup, location=location.belowbar, color=color.green)
plotshape(sellSignal, title="Sell", style=shape.triangledown, location=location.abovebar, color=color.red)

Example 4: Bollinger Bands

//@version=6
indicator("Bollinger Bands", overlay=true)
length = input.int(20, title="Length")
mult = input.float(2.0, title="Multiplier")
basis = ta.sma(close, length)
dev = mult * ta.stdev(close, length)
upper = basis + dev
lower = basis - dev
plot(basis, title="Basis", color=color.blue)
plot(upper, title="Upper", color=color.red)
plot(lower, title="Lower", color=color.green)
fill(plot(upper), plot(lower), color=color.new(color.blue, 90))

Important Limitations

Please read this section carefully before using custom indicators.

Due to the complex nature of Pine Script and the transpilation process involving third-party libraries, there are significant limitations to what can be supported.

 

Unsupported Features

Feature Reason
Arrays (array.new_float, array.get, array.set, etc.) Complex state management not supported
Maps (map.new, map.get, etc.) Not implemented in the runtime
Drawing Objects (line.new, label.new, box.new, table.new) Chart drawing API not available
Strategy Functions (strategy.entry, strategy.exit, etc.) Only indicators supported, not strategies
Request Functions (request.security, request.financial, etc.) External data requests not supported
Alert Functions (alertcondition, alert) Alert system not integrated
Custom Types (type, method) User-defined types not supported
Persistent Variables with Arrays (var float[] arr = ...) Complex state not supported
varip Variables Intrabar persistence not available

 

Partially Supported Features

Feature Limitation
Custom Functions with Color Returns Functions that return color.rgb() may not work correctly
Multi-line Custom Functions Complex function bodies with comma-separated declarations may have issues
color.from_gradient() Gradient colors may be replaced with default colors
Session-based Logic Limited timezone support
max_bars_back May not be honored exactly

 

Known Issues

  1. Comma-separated variable declarations inside custom functions (e.g., r1 = 173.0, g1 = 216.0) may not parse correctly
  2. Custom color gradient functions are automatically replaced with a default blue color
  3. Very complex nested calculations may produce unexpected results
  4. Some Pine Script v6 syntax may not be fully supported

 !! Beta Feature Disclaimer !!

THIS IS A BETA FEATURE.

By using custom Pine Script indicators, you acknowledge and accept the following:

  1. No Guarantees: Due to the complex nature of Pine Script transpilation and the use of third-party libraries, we cannot guarantee that any indicator will work correctly, produce accurate results, or work at all.
  2. Use at Your Own Risk: Custom indicators are provided as-is. Trading decisions based on custom indicator outputs are entirely your responsibility.
  3. Accuracy Not Verified: We do not verify that transpiled indicators produce the same results as they would on TradingView. Differences in calculation methods, data precision, and timing may cause variations.
  4. Feature May Change: As a beta feature, functionality may change, break, or be removed without notice.
  5. Performance Impact: Complex indicators may impact chart loading times and browser performance.

Support is Available ONLY via Email. For questions, issues, or suggestions regarding custom Pine Script indicators, please contact us at  with as much information as you can.

What to Include in Your Email

When reporting an issue, please include:

  1. The complete Pine Script code you're trying to use
  2. The error message (if any) from the browser console
  3. A description of what you expected vs. what happened
  4. Screenshots if applicable

What We CAN Help With

  • Clarifying which features are supported
  • General guidance on simplifying indicators for compatibility
  • Potentially improving the indicator support (bug fixes)

What We CANNOT Do

  • We cannot fix your specific indicators. If an indicator uses unsupported features, we cannot rewrite it for you.
  • We cannot guarantee compatibility with any specific indicator.
  • We cannot provide Pine Script programming support. This is not a Pine Script tutorial service.
  • We cannot reverse-engineer protected/paid indicators.

We're continuously working to improve this feature. If you have suggestions for:

  • Additional Pine Script functions to support
  • Bug reports with reproducible examples
  • General feature improvements

Please send them to [email protected] with the subject line: "Custom TradingView Indicator Suggestion"

We prioritize suggestions that:

  • Include clear, reproducible examples
  • Benefit a wide range of users
  • Are technically feasible to implement

Tips for Best Results

Do This

  1. Start simple - Test with basic indicators first before trying complex ones
  2. Use supported TA functions - Stick to the documented supported functions
  3. Avoid arrays and maps - Rewrite logic to not use array operations if possible
  4. Use standard colors - Use color.red, color.green, etc., instead of custom color functions
  5. Test incrementally - Add features one at a time to identify what breaks

Avoid This

  1. Don't use paid/protected indicators (they're usually obfuscated)
  2. Don't use indicators that heavily rely on arrays or tables
  3. Don't use strategy scripts (only indicators are supported)
  4. Don't use request.security() for multi-timeframe analysis
  5. Don't expect exact parity with TradingView results

Conclusion

Custom Pine Script indicators on TradesViz charts open up exciting possibilities for traders who want to use their favorite TradingView indicators alongside their trade analysis. While this beta feature has limitations, it supports a wide range of common technical analysis functions and plot types.

Remember: this is a beta feature with inherent limitations. Start with simple indicators, test thoroughly, and reach out to [email protected] if you have questions or suggestions.
