Line range hint 1-27: Consider updating package documentation

The package documentation provides a good overview of the volume strategy functions. However, with the addition of the Chaikin Money Flow Strategy, it might be beneficial to update the package comment to mention this new strategy explicitly, especially if it's a significant addition to the package's functionality.

Consider adding a brief mention of the Chaikin Money Flow Strategy in the package comment, for example:

 // Package volume contains the volume strategy functions.
 //
 // This package belongs to the Indicator project. Indicator is
 // a Golang module that supplies a variety of technical
 // indicators, strategies, and a backtesting framework
 // for analysis.
+//
+// Available strategies include:
+// - Money Flow Index (MFI)
+// - Chaikin Money Flow (CMF)
 //
 // # License
strategy/volume/chaikin_money_flow_strategy_test.go (3)

17-37: LGTM: Well-structured test function with appropriate error handling.

The TestChaikinMoneyFlowStrategy function is well-implemented, with good error handling and use of helper functions. It effectively tests the Chaikin Money Flow strategy by comparing computed results with expected outcomes.

Consider adding a descriptive comment at the beginning of the function to explain its purpose and the strategy being tested. This would enhance the test's documentation and make it easier for other developers to understand the test's intent.


39-55: LGTM: Well-implemented test for strategy report generation.

The TestChaikinMoneyFlowStrategyReport function effectively tests the report generation capability of the Chaikin Money Flow strategy. It demonstrates good practices such as proper error handling and cleanup of test artifacts.

Consider the following improvements:

  1. Add a check to verify the contents of the generated HTML file. This could involve reading the file back and asserting on its contents or structure.
  2. Use a temporary directory for the output file instead of the current directory. This can be achieved using os.MkdirTemp().

Here's an example of how you might implement these suggestions:

func TestChaikinMoneyFlowStrategyReport(t *testing.T) {
	// ... (existing code)

	// Create a temporary directory for the test
	tempDir, err := os.MkdirTemp("", "cmfs_test")
	if err != nil {
		t.Fatal(err)
	}
	defer os.RemoveAll(tempDir) // Clean up

	fileName := filepath.Join(tempDir, "chaikin_money_flow_strategy.html")

	err = report.WriteToFile(fileName)
	if err != nil {
		t.Fatal(err)
	}

	// Verify file contents
	content, err := os.ReadFile(fileName)
	if err != nil {
		t.Fatal(err)
	}

	// Add assertions on the content
	if !strings.Contains(string(content), "Chaikin Money Flow Strategy") {
		t.Error("Report does not contain expected content")
	}
}

These changes would enhance the robustness of the test by verifying the output and ensuring clean test execution.


18-26: Enhance test data documentation and error handling.

While the use of CSV files for test data is commendable, there are opportunities to improve the documentation and robustness of the test data handling:

  1. Add comments describing the structure and purpose of the CSV files used in the tests.
  2. Consider implementing more specific error handling for different types of errors that might occur during file reading.

Here's an example of how you might implement these suggestions:

// testdata/brk-b.csv contains historical price and volume data for Berkshire Hathaway Inc. (BRK.B)
// Format: Date,Open,High,Low,Close,Volume
snapshots, err := helper.ReadFromCsvFile[asset.Snapshot]("testdata/brk-b.csv", true)
if err != nil {
	if os.IsNotExist(err) {
		t.Fatal("Test data file not found: testdata/brk-b.csv")
	}
	t.Fatalf("Failed to read test data: %v", err)
}

// testdata/chaikin_money_flow_strategy.csv contains expected strategy results
// Format: Date,Action
results, err := helper.ReadFromCsvFile[strategy.Result]("testdata/chaikin_money_flow_strategy.csv", true)
if err != nil {
	if os.IsNotExist(err) {
		t.Fatal("Expected results file not found: testdata/chaikin_money_flow_strategy.csv")
	}
	t.Fatalf("Failed to read expected results: %v", err)
}

These changes would provide more context about the test data and improve error reporting.

strategy/volume/money_flow_index_strategy.go (1)

96-96: Updated comment for accuracy

The comment has been correctly updated to reflect that closings[1] contains the "money flow index" instead of "superTrend". This change improves code clarity and prevents potential confusion.

Consider capitalizing "Money Flow Index" in the comment for consistency with the strategy name:

-//                 closings[1] -> money flow index
+//                 closings[1] -> Money Flow Index

🛠️ Refactor suggestion

Consider adding more test cases for improved coverage.

The current test file provides good coverage of the main functionalities of the Chaikin Money Flow strategy. However, to enhance the robustness of the tests, consider adding the following:

  1. Edge case tests (e.g., empty data set, single data point).
  2. Error scenario tests (e.g., malformed input data).
  3. Tests with different parameter values for the strategy.

Here's an example of how you might implement an edge case test:

func TestChaikinMoneyFlowStrategyEdgeCases(t *testing.T) {
	cmfs := volume.NewChaikinMoneyFlowStrategy()

	t.Run("EmptyDataSet", func(t *testing.T) {
		result := cmfs.Compute([]asset.Snapshot{})
		if len(result) != 0 {
			t.Errorf("Expected empty result for empty input, got %v", result)
		}
	})

	t.Run("SingleDataPoint", func(t *testing.T) {
		snapshot := asset.Snapshot{/* initialize with test data */}
		result := cmfs.Compute([]asset.Snapshot{snapshot})
		// Add assertions based on expected behavior for a single data point
	})
}

Adding these tests would increase confidence in the strategy's behavior across various scenarios.

⚠️ Potential issue

Incorrect description of the strategy's Buy and Sell signals

The comments describe the strategy as recommending a Sell action when the Chaikin Money Flow crosses above 0 and a Buy action when it crosses below 0. However, traditionally, when the Chaikin Money Flow crosses above 0, it indicates buying pressure, suggesting a Buy signal. Conversely, crossing below 0 indicates selling pressure, suggesting a Sell signal.

Apply this diff to correct the description:

⚠️ Potential issue

Reverse the logic in action mapping to align with standard CMF interpretation

In the Compute method, the current logic assigns a Buy action when cmf < 0 and a Sell action when cmf > 0. This is the opposite of the standard interpretation of the Chaikin Money Flow indicator. Typically, a positive CMF indicates buying pressure, suggesting a Buy signal, and a negative CMF indicates selling pressure, suggesting a Sell signal.

Apply this diff to correct the logic:

 actions := helper.Map(cmfs, func(cmf float64) strategy.Action {
-    if cmf < 0 {

66-76: LGTM: ChaikinMoneyFlowStrategy type definition

The ChaikinMoneyFlowStrategy type is well-defined and documented. The description clearly explains its purpose and behavior.

Consider adding a brief explanation of what the Chaikin Money Flow indicator represents, as it might not be familiar to all readers. For example:

 ChaikinMoneyFlowStrategy represents the configuration parameters for calculating the Chaikin Money Flow strategy. Recommends a Buy action when it crosses above 0, and recommends a Sell action when it crosses below 0.
+The Chaikin Money Flow indicator measures the buying and selling pressure of an asset over a specific period.

78-85: Improve readability with minor grammatical adjustment

The function description is clear, but it can be improved by adding the article "the" before "default parameters". Consider updating the sentence to:

- NewChaikinMoneyFlowStrategy function initializes a new Chaikin Money Flow strategy instance with default parameters.
+ NewChaikinMoneyFlowStrategy function initializes a new Chaikin Money Flow strategy instance with the default parameters.

This small change enhances readability and addresses the grammatical suggestion.
