Troubleshooting: Backtest Not Showing Results in TradingView

If you're a trader using TradingView, you may encounter issues with your backtests not yielding any results, especially when it comes to implementing a Simple Moving Average (SMA) crossover strategy. This can be frustrating, particularly if you are confident in the code you’ve written. In this guide, we'll delve into a common pitfall associated with a SMA crossover script and provide a clear solution to fix the issue.

The Problem

You may have a Pine Script for a SMA crossover strategy like the one provided below. Despite having no errors during compilation, your backtest results return empty. Here’s a code snippet that represents the situation:

The key issue arises with the strategy.close() line where an unknown trade ID "sell" is used incorrectly.

Analyzing the Solution

To resolve the problem and ensure that backtest results are properly displayed, follow these steps:

1. Understand the strategy.entry() and strategy.close() Functions

The strategy.entry() function requires a unique identifier for trade entries, allowing you to manage positions later. The strategy.close() function must reference an existing trade ID that was used in strategy.entry().

2. Correct the Trade ID

In the original script, the line:

uses "sell" as the trade ID. However, this ID never matches any strategy.entry() call, producing no results in your backtest.

3. Update Your Code

Correct the trade ID in the strategy.close() function to ensure consistency with your strategy.entry():

Conclusion

By correcting the trade ID in your strategy.close() function to match the ID from your strategy.entry(), you can finally see your backtest results. Fixing this small but crucial detail can transform your Pine Script experience in TradingView from one of frustration to success.
