📖 Quick Start

Basic Usage

from pytradingview import TVEngine

if __name__ == '__main__':
    # Initialize the engine
    engine = TVEngine()
    
    # Setup and run with custom indicators
    engine.get_instance().setup('./indicators').run()

Creating Custom Indicators

from pytradingview.indicators import (
    TVIndicator,
    TVSignal,
    TVDrawable,
    IndicatorConfig,
    InputType,
    InputDefinition,
    register_indicator
)
import pandas as pd
from typing import List, Tuple

@register_indicator(name="MyIndicator", enabled=True)
class MyCustomIndicator(TVIndicator):
    """
    Custom indicator example
    """
    
    def get_config(self) -> IndicatorConfig:
        """Define indicator configuration"""
        return IndicatorConfig(
            name="My Custom Indicator",
            version="1.0.0",
            description="A simple custom indicator",
            author="Your Name",
            enabled=True,
            inputs=[
                InputDefinition(
                    id="period",
                    display_name="Period",
                    type=InputType.INTEGER,
                    default_value=14,
                    min_value=1,
                    max_value=100
                )
            ]
        )
    
    def calculate(self, df: pd.DataFrame) -> Tuple[List[TVSignal], List[TVDrawable]]:
        """Calculate indicator signals"""
        signals = []
        drawables = []
        
        # Your indicator logic here
        # ...
        
        return signals, drawables

Working with Charts

from pytradingview import TVWidget, TVChart

# Get the widget instance
widget = TVWidget.get_instance("widget_id")

# Get active chart
chart = await widget.activeChart()

# Create a shape on the chart
from pytradingview.shapes import TVTrendLine, TVShapePoint

trend_line = TVTrendLine()
await chart.createMultipointShape(
    points=[
        TVShapePoint(time=1234567890, price=50000),
        TVShapePoint(time=1234567900, price=51000)
    ],
    shape=trend_line
)

Custom Datafeed

from pytradingview.datafeed import (
    TVDatafeed,
    TVLibrarySymbolInfo,
    TVBar,
    TVHistoryMetadata
)

class MyDatafeed(TVDatafeed):
    """Custom datafeed implementation"""
    
    def resolveSymbol(self, symbolName, onResolve, onError, extension=None):
        """Resolve symbol information"""
        symbol_info = TVLibrarySymbolInfo(
            name=symbolName,
            ticker=symbolName,

            listed_exchange="MyExchange",
            timezone="Etc/UTC",
            format="price",
            pricescale=100,
            minmov=1,
            has_intraday=True,
            supported_resolutions=["1", "5", "15", "60", "D", "W", "M"]
        )
        onResolve(symbol_info)
    
    def getBars(self, symbolInfo, resolution, periodParams, onResult, onError):
        """Get historical bars"""
        # Fetch your data here
        bars = [
            TVBar(
                time=1234567890000,  # milliseconds
                open=50000,
                high=51000,

                volume=1000
            ),
            # ... more bars
        ]

        onResult(bars, metadata)
