What Is a Pine Script Strategy?

A Pine Script strategy is a special type of script on TradingView that allows your code to simulate trades, run backtests, and generate performance statistics. Unlike indicators, strategies can enter long and short positions, calculate profit and loss, and tell you if your trading idea actually works.

Script Types (Indicator vs Strategy)

• Indicators only display information on a chart.
• Strategies place virtual trades so you can analyze performance.

This difference is essential because only strategies produce the performance report, the heart of this article.

Why Backtesting Matters for Traders

Backtesting helps you answer critical questions:

• Does the strategy work historically?
• How big are losses during bad periods?
• Is the approach consistent or lucky?

The performance report gives you those answers in one place.

Understanding the Strategy Performance Report

TradingView automatically generates this report when you run a script containing strategy() instead of indicator(). At first glance, it looks technical, but each section follows a simple purpose: summarize the strategy’s results and risk.

Overview of Key Report Sections

The report includes:

• Performance Summary
• List of Trades
• List of Orders
• Equity Curve
• Risk Metrics

Let’s break each part down.

Performance Summary Explained

Here are the most important values:

Metric	Meaning
Net Profit	Total earnings after subtracting losses
Win Rate	How many trades were profitable
Max Drawdown	Worst drop from peak equity
Profit Factor	Ratio of gross profit to gross loss
Sharpe Ratio	A measure of consistency and risk-adjusted return
Expectancy	Average profit per trade

You can think of these metrics as a “report card” for your strategy.

Trade List Overview

This table shows every trade taken:

• Entry price
• Exit price
• Profit or loss
• Duration

It’s helpful for spotting patterns, such as whether losing trades last longer or if winners come during specific sessions.

List of Trades vs List of Orders

• Trades show completed positions from entry to exit.
• Orders record all instructions issued (market, limit, stop).

The trades list is better for learning performance; the orders list is useful for debugging.

Core Metrics in the Strategy Performance Report

Net Profit & Gross Profit/Loss

• Net Profit = Gross Profit – Gross Loss
  It’s tempting to judge a strategy solely by this number, but that’s risky. A strategy can have high net profit while hiding dangerous drawdowns.

Max Drawdown Explained Simply

Max drawdown tells you the largest loss from the highest equity peak.
If a strategy makes $10,000 but suffers a $7,000 drawdown, it’s too risky for most traders.

Profit Factor & Sharpe Ratio

• Profit Factor (PF)
  • PF > 1 means profitable
  • PF > 1.5 is strong
  • PF > 2 is excellent
• Sharpe Ratio
  Higher Sharpe = more stable and less volatile returns.

Average Trade & Expectancy

Expectancy answers a simple question:

“On average, how much do I gain or lose every time I trade?”

Positive expectancy is mandatory for a viable system.

How Strategy Inputs Affect Performance

Stop Loss & Take Profit

Changing exit rules dramatically shifts metrics like:

• Win rate
• Drawdown
• Average trade
• Profit factor

Tighter stops reduce drawdown but may increase losses from market noise.

Position Sizing Methods

Different strategies include:

• Fixed size
• Percentage of equity
• Scaling (pyramiding)

Risk grows with dynamic sizing, but so can profits.

Strategy Parameters & Optimization

Optimization helps you find the most effective settings, like:

• MA length
• RSI threshold
• ATR multiplier

Always avoid over-optimization—too much tuning can make results unrealistic.

How to Read the Equity Curve

Smooth vs Choppy Curves

• Smooth upward curve → consistent strategy
• Choppy or flat curve → unstable or weak strategy
• Sudden big drops → high drawdown and hidden risk

What Equity Shape Reveals About Strategy Health

A reliable strategy grows steadily, even with occasional dips. If the curve looks like a heart monitor, reconsider your approach.

Common Mistakes When Reading the Performance Report

Overfitting & Curve Fitting

This happens when you tailor a strategy too tightly to historical data. It performs perfectly in backtests but fails in live markets.

Ignoring Drawdown

High profit means nothing if the strategy nearly wipes out the account.

Misunderstanding Win Rate

A 90% win rate can still blow up if rare losses are massive.

Example Pine Script Strategy With Report Explanation

Basic Moving Average Strategy Code

Here’s an extremely simple example to illustrate how performance reports work:

//@version=5
strategy("Simple MA Strategy", overlay=true, initial_capital=10000)

fast = ta.sma(close, 9)
slow = ta.sma(close, 21)

longCond = ta.crossover(fast, slow)
shortCond = ta.crossunder(fast, slow)

if longCond
    strategy.entry("Long", strategy.long)

if shortCond
    strategy.entry("Short", strategy.short)

What the Report Tells Us About This Strategy

• Trend markets produce profitable trades.
• Range markets cause whipsaws and reduce win rate.
• Drawdown increases during choppy conditions.
• Profit factor may be modest but steady on trending pairs.

The report reveals strengths and weaknesses you wouldn’t see by eyeballing the chart.
