Nota Keluaran

A non-compounding, fixed-notional Bollinger-Band reversion strategy designed for pair trading. Includes MA-based exits, optional stop-loss + time-stop, synthetic Sharpe calculation, and on-chart performance table. Configured to align with TradingView’s Strategy Tester metrics.

Overview

This strategy implements a fixed-notional, non-compounding Bollinger-Band reversion system suitable for pair trading. It is designed to operate on ratio charts (e.g., PLD/REXR) or any spread expression the user applies.

Trades are entered on the next bar following a band-cross signal, and exits can be triggered by a moving-average cross, an optional time-stop, or an optional stop-loss.

The strategy sizes each trade with a constant notional amount (e.g., $100,000), ensuring stable performance reporting across long histories and preventing unintended compounding.

Features

Entry Conditions

• Long entry when price crosses below the lower Bollinger Band.
  
• Short entry when price crosses above the upper Bollinger Band.
  
• Optional “close-only” mode to require the close to cross the bands.
  

Exit Conditions

• Moving-average cross exit.
  
• Optional time-stop (e.g., exit after 5 bars).
  
• Optional stop-loss based on percentage move relative to entry.
  

Trade Sizing

• Uses strategy.cash with fixed notional sizing per trade.
  
• Prevents compounding so results remain stable and comparable across instruments.
  

On-Chart Performance Summary

• Total PnL (%) based on strategy.netprofit.
  
• Average PnL per trade (%).
  
• Win rate.
  
• Annualised Sharpe ratio computed from synthetic daily returns.
  
• All statistics are aligned with TradingView’s Strategy Tester.
  

Visual Markers

• Entry/exit markers (L, S, C, TS, SL).
  
• Optional pre-cost PnL labels at closing bars.
  

Alert Triggers
