Click "Pine Editor" at bottom of screen. This opens the code editor where you'll write your strategy.
Click "Open" → "New blank strategy". This generates template code with basic strategy structure.
Define entry/exit conditions using Pine Script. Example: Buy when RSI < 30, sell when RSI > 70.
Click "Add to Chart". Your strategy runs automatically and displays trades on the chart.
Open "Strategy Tester" tab at bottom. See profit, win rate, drawdown, and trade list.
TradingView requires coding. Unlike no-code platforms, you must write Pine Script to backtest. If you're not a programmer, expect a 2-4 week learning curve before building complex strategies.
//@version=5
strategy("SMA Crossover", overlay=true)
// Define moving averages
fastMA = ta.sma(close, 10)
slowMA = ta.sma(close, 50)
// Entry conditions
longCondition = ta.crossover(fastMA, slowMA)
shortCondition = ta.crossunder(fastMA, slowMA)
// Execute trades
if (longCondition)
strategy.entry("Long", strategy.long)
if (shortCondition)
strategy.entry("Short", strategy.short)
// Plot MAs on chart
plot(fastMA, color=color.blue, title="Fast MA")
plot(slowMA, color=color.red, title="Slow MA")This basic strategy buys when 10-period MA crosses above 50-period MA, sells on crossunder. Simple but demonstrates Pine Script structure.
Free/Essential limited to 20K bars. This varies by timeframe:
Impact: Can't properly test intraday strategies over multiple years.
Complex strategies take 30-120 seconds to backtest. Simple indicators load faster, but multi-condition strategies with loops become painfully slow.
Impact: Testing parameter variations becomes impractical.
Manual parameter testing only. Want to test RSI from 10-40 in steps of 5? You must manually change code 7 times and record results yourself.
Impact: Finding optimal parameters takes hours instead of seconds.
Basic metrics only: Net profit, profit factor, max drawdown, win rate. Missing: Sharpe ratio, Sortino ratio, Calmar ratio, MAR ratio, profit distribution analysis.
Impact: Can't properly assess risk-adjusted returns.
| Metric | Good | Red Flag |
|---|---|---|
| Bars tested | Max out 20K bars; confirm higher timeframes cover years | Only a few months of data |
| Execution time | <30s for strategy runs | Minutes per run; frequent timeouts |
| Cost/slippage model | Fees + realistic slippage per venue | Mid-price fills; costs ignored |
| Metric depth | PF 1.4-2.0, max DD <25%, export trades for deeper stats | PF >3.0 with tiny samples; no drawdown context |
| Lookahead bias | No `security()` repainting; alert testing; walk-forward elsewhere | Uses future data or repainting indicators |
| Feature | TradingView | BacktestMe | Other Pro Tools |

Scenario: Sarah had a 5-minute RSI strategy on TradingView. It worked on her 70-day backtest.
Problem: Couldn't test beyond 70 days (20K bar limit). Wanted to optimize RSI period but manually testing 30 variations took 3 hours.
Solution: Switched to BacktestMe. Tested 5 years of data in 8 seconds. Genetic optimization found optimal parameters in 2 minutes. Strategy failed on longer timeframe - saved her from losing real money!
To backtest on TradingView: 1) Open Pine Editor, 2) Write strategy code using Pine Script, 3) Click "Add to Chart", 4) View results in Strategy Tester tab. Basic strategies work well, but complex multi-indicator systems require coding. TradingView is free for simple tests, but lacks advanced features like walk-forward analysis and genetic optimization.
TradingView is good for beginners and simple strategies. Pros: Free access, beautiful charts, large community. Cons: Requires Pine Script coding, limited to 20,000 bars, no advanced optimization, slow execution on complex strategies. For serious traders, professional platforms offer better data quality, faster execution, and advanced features.
Key limitations: 20,000 bar limit (varies by timeframe), no multi-timeframe optimization, slow execution (30+ seconds for complex strategies), limited position sizing options, no genetic algorithms, no walk-forward analysis, basic performance metrics only, and Pine Script learning curve. These become problematic for professional traders.
