PineWealth

PineWealth is a community-driven translator that converts TradingView's Pine Script strategies into WealthLab 8 C# Strategies.

🚀 Empower Pine Script users with WealthLab’s powerful backtesting and portfolio simulation engine.

---

🔍 What It Does

PineWealth reads Pine Script code and translates it into WealthLab 8-compatible C# strategy code. This allows traders to take their strategies from TradingView and leverage WealthLab’s advanced features like:

• Portfolio level backtesting with survivorship-bias free DataSets
• Advanced backtesting Visualizers
• Position sizing and risk control
• Optimization (parallel, walk-forward, symbol-by-symbol)

---

✨ Why This Exists

TradingView's scripting language is powerful and widely used, but its backtesting capabilities are limited. WealthLab 8 brings professional-grade performance testing, and PineWealth bridges the gap.

Use it to:

• Migrate strategies from TradingView to WealthLab
• Extend strategies using full C# flexibility
• Enhance your workflow and simulations

---

✅ Supported Features (So far)

• Basic indicator detection
• long/short entry/exit logic
• Variable declaration and assignments
• Auto-initialization of indicators in Initialize() method

---

🔜 Roadmap

• Support full set of indicators in ta library (WIP, about half complete)
• Add support for MACD and other tuple-based indicators
• Support assignment of tuples directly to variable, then accessing tuple members later
• Position sizing
• Convert Inputs into Strategy Parameters
• Translate plots

---

💻 How It Works

PineWealth uses a custom line-by-line parser with lightweight tokenization. It reads Pine Script lines and emits WealthLab-ready C# code. Indicator objects are declared and initialized properly in the Initialize() method.

Example:
Pine Script

//@version=4
strategy("RSI Overbought/Oversold", overlay=true)

x = 20
rsi = ta.rsi(close, 14)
[middle, upper, lower] = ta.bb(close, 20, 20)

if (rsi > 70)
    strategy.entry("Short", strategy.short)
    x++

if (rsi < 30)
    strategy.entry("Long", strategy.long)
    x--

becomes WealthLab C#:

using WealthLab.Backtest;
using System;
using WealthLab.Core;
using WealthLab.Data;
using WealthLab.Indicators;
using System.Collections.Generic;

namespace WealthScript1 
{
   public class MyStrategy : UserStrategyBase
   {
      //create indicators and other objects here, this is executed prior to the main trading loop
      public override void Initialize(BarHistory bars)
      {
         rsi = RSI.Series ( bars.Close , 14 ) ;
         middle = BBUpper.Series(bars.Close, 20, 20 );
         upper = SMA.Series(bars.Close, 20 );
         lower = BBLower.Series(bars.Close, 20, 20 );

      }
       
      //execute the strategy rules here, this is executed once for each bar in the backtest history
      public override void Execute(BarHistory bars, int idx)
      {
         x = 20 ; 
         if ( rsi[idx] > 70 ) 
         {
            if (HasOpenPosition(bars, PositionType.Long))
               PlaceTrade(bars, TransactionType.Sell, OrderType.Market);
            PlaceTrade(bars, TransactionType.Short, OrderType.Market, 0, "Short"); 
            x ++ ; 
         }
         if ( rsi[idx] < 30 ) 
         {
            if (HasOpenPosition(bars, PositionType.Short))
               PlaceTrade(bars, TransactionType.Cover, OrderType.Market);
            PlaceTrade(bars, TransactionType.Buy, OrderType.Market, 0, "Long"); 
            x -- ; 
         }

      }
       
      //declare private variables below
      private double x;
      private RSI rsi;
      private BBUpper middle;
      private SMA upper;
      private BBLower lower;
   }
}
