Overview

This skill exports a Vibe-Trading strategy to all major trading platforms in one go. Output file: artifacts/strategy.pine (inside the run directory).

Supported platforms (always generate ALL):

Workflow: Export from Backtest

1. load_skill("pine-script") — read this guide
2. read_file("config.json") — understand instruments, dates, parameters
3. read_file("code/signal_engine.py") — understand the Python strategy logic
4. Translate the strategy to ALL platforms using the references below
5. write_file("artifacts/strategy.pine") — save the combined output
6. Return the code in a code block with usage instructions per platform

Workflow: Generate from Description

1. load_skill("pine-script") — read this guide
2. Write indicator/strategy code for ALL platforms based on the user's description
3. write_file("artifacts/strategy.pine") — save the combined output
4. Return the code with usage instructions

//@version=6
strategy("Strategy Name", overlay=true, default_qty_type=strategy.percent_of_equity, default_qty_value=100, commission_type=strategy.commission.percent, commission_value=0.1, initial_capital=1000000)

Signal Logic

Position Sizing

Syntax Rules (Critical)

1. Version declaration must be first line: //@version=6
2. Ternary operators MUST stay on one line: text = condition ? "a" : "b"
3. Line continuation: continuation lines must be indented MORE than the starting line
4. No plot() in local scope (if/for/function) — use plot(condition ? value : na)
5. var: persistent state across bars; regular assignment recalculates each bar
6. Avoid repainting: use barstate.isconfirmed, lookahead=barmerge.lookahead_off
7. Limits: max 500 bars lookback, 500 plot calls, 64 entry/exit per bar, 40 request.security()

2. 通达信 / 同花顺 / 东方财富 — TDX Formula

These platforms share 95%+ identical formula syntax. Write ONE version that works on all three.

Template

{Vibe-Trading 策略导出}
{策略名称: XXX}

{——————— 参数 ———————}
N:=14;
M:=6;

{——————— 指标计算 ———————}
RSI_VAL:=RSI(CLOSE,N);
MA_FAST:=MA(CLOSE,5);
MA_SLOW:=MA(CLOSE,20);

{——————— 买卖信号 ———————}
BUY:CROSS(MA_FAST,MA_SLOW) AND RSI_VAL<40,COLORRED;
SELL:CROSS(MA_SLOW,MA_FAST) AND RSI_VAL>60,COLORGREEN;

DRAWTEXT(BUY,LOW,'B'),COLORYELLOW;
DRAWTEXT(SELL,HIGH,'S'),COLORWHITE;

Python → TDX Mapping

Syntax Rules

1. Assignment: := for intermediate variables, : for output (plotted) lines
2. Comments: {comment} — curly braces, NOT //
3. No semicolons optional: each statement ends with ;
4. Colors: COLORRED, COLORGREEN, COLORYELLOW, COLORWHITE, COLORBLUE, COLORCYAN, COLORMAGENTA
5. Line styles: LINETHICK2, POINTDOT, STICK, VOLSTICK
6. Draw text: DRAWTEXT(COND, PRICE, 'TEXT'), COLOR;
7. Draw icon: DRAWICON(COND, PRICE, ICON_ID);
8. All function/variable names UPPERCASE
9. No loops / no arrays — everything is vectorized bar-by-bar
10. Max formula length: ~10,000 characters per formula

Platform Differences

For maximum compatibility, avoid platform-specific extensions. Stick to core functions.

3. MetaTrader 5 — MQL5

Template (Custom Indicator)

//+------------------------------------------------------------------+

input int InpPeriod = 14;  // Period

double BuyBuffer[];
double SellBuffer[];

int OnInit()
{
   SetIndexBuffer(0, BuyBuffer, INDICATOR_DATA);
   SetIndexBuffer(1, SellBuffer, INDICATOR_DATA);
   PlotIndexSetInteger(0, PLOT_ARROW, 233);  // up arrow
   PlotIndexSetInteger(1, PLOT_ARROW, 234);  // down arrow
   PlotIndexSetInteger(0, PLOT_DRAW_TYPE, DRAW_ARROW);
   PlotIndexSetInteger(1, PLOT_DRAW_TYPE, DRAW_ARROW);
   return(INIT_SUCCEEDED);
}

int OnCalculate(const int rates_total,
                const int prev_calculated,
                const datetime &time[],
                const double &open[],
                const double &high[],
                const double &low[],
                const double &close[],
                const long &tick_volume[],
                const long &volume[],
                const int &spread[])
{
   int start = MathMax(prev_calculated - 1, InpPeriod);
   for(int i = start; i < rates_total; i++)
   {
      BuyBuffer[i]  = EMPTY_VALUE;
      SellBuffer[i] = EMPTY_VALUE;

      // === YOUR LOGIC HERE ===
      // Example: if(buyCondition) BuyBuffer[i] = low[i];
      //          if(sellCondition) SellBuffer[i] = high[i];
   }
   return(rates_total);
}

Python → MQL5 Mapping

Syntax Rules

1. Indicator handles: call iMA() etc. in OnInit(), use CopyBuffer() to get values
2. Buffer direction: MQL5 buffers are indexed 0=oldest by default; use ArraySetAsSeries() to reverse
3. EMPTY_VALUE: use for "no signal" on arrow plots
4. Indicator vs EA: generate indicator (.mq5), not Expert Advisor, to match "indicator export" purpose
5. Handle-based API: MQL5 uses handles — create in OnInit, read in OnCalculate

Symbol Format Mapping

When generating code, map Vibe-Trading instrument codes appropriately:

Note: Most indicator code is instrument-agnostic — the user applies it to whatever chart they're viewing. Include a comment noting the original instrument for reference only.

Limitations & Transparency

When a Python strategy uses features that can't be directly translated, clearly note it:

Always add a comment block at the top listing any features that could not be translated.

Quality Checklist

Before outputting:

• ALL 3 platform sections are included (Pine Script, TDX, MQL5)
• Each platform section has proper header with usage instructions
• Pine Script: //@version=6 is first line, no plot() in local scope, ternary on single lines
• TDX: all uppercase functions, := for intermediate, : for output, {comments}
• MQL5: proper handle-based API, EMPTY_VALUE for no-signal
• Entry/exit conditions match the Python signal logic semantically across ALL platforms
• Untranslatable features are clearly documented at the top of each section
• Comment header notes the original Vibe-Trading run_id and instrument
