# GHZ Load Test Enum Format Fix - Agent 291

## Issue
ghz load test scripts were using incorrect proto enum values that don't match the trading.proto definitions.

### Incorrect Format (Before)
```json
{
  "side": "BUY",           // ❌ Wrong
  "order_type": "LIMIT"    // ❌ Wrong
}
```

### Correct Format (After)
```json
{
  "side": "ORDER_SIDE_BUY",      // ✅ Correct
  "order_type": "ORDER_TYPE_LIMIT" // ✅ Correct
}
```

## Proto Definitions (tli/proto/trading.proto)

### OrderSide Enum (lines 348-352)
```protobuf
enum OrderSide {
  ORDER_SIDE_UNSPECIFIED = 0;
  ORDER_SIDE_BUY = 1;
  ORDER_SIDE_SELL = 2;
}
```

### OrderType Enum (lines 355-361)
```protobuf
enum OrderType {
  ORDER_TYPE_UNSPECIFIED = 0;
  ORDER_TYPE_MARKET = 1;
  ORDER_TYPE_LIMIT = 2;
  ORDER_TYPE_STOP = 3;
  ORDER_TYPE_STOP_LIMIT = 4;
}
```

## Files Fixed

### 1. tests/load_tests/ghz_authenticated.sh
**Changes**: 8 enum value corrections across 4 test scenarios

- **Test 1 (lines 100-101)**: BUY → ORDER_SIDE_BUY, LIMIT → ORDER_TYPE_LIMIT
- **Test 2 (lines 144-145)**: SELL → ORDER_SIDE_SELL, LIMIT → ORDER_TYPE_LIMIT
- **Test 3 (lines 187-188)**: BUY → ORDER_SIDE_BUY, MARKET → ORDER_TYPE_MARKET
- **Test 4 (lines 230-231)**: randomString pattern updated to use correct enums

### 2. tests/load_tests/ghz_authenticated_fixed.sh
**Changes**: 8 enum value corrections (identical to ghz_authenticated.sh)

- **Test 1 (lines 100-101)**: BUY → ORDER_SIDE_BUY, LIMIT → ORDER_TYPE_LIMIT
- **Test 2 (lines 144-145)**: SELL → ORDER_SIDE_SELL, LIMIT → ORDER_TYPE_LIMIT
- **Test 3 (lines 187-188)**: BUY → ORDER_SIDE_BUY, MARKET → ORDER_TYPE_MARKET
- **Test 4 (lines 230-231)**: randomString pattern updated to use correct enums

### 3. tests/load_tests/ghz_quick_test.sh
**Changes**: 2 enum value corrections

- **Lines 34-35**: BUY → ORDER_SIDE_BUY, LIMIT → ORDER_TYPE_LIMIT

### 4. tests/load_tests/ghz_quick_auth_test.sh
**Status**: ✅ Already correct (no changes needed)

- Already using ORDER_SIDE_BUY and ORDER_TYPE_MARKET

## Summary

| Script | Before | After | Status |
|--------|--------|-------|--------|
| ghz_authenticated.sh | 8 incorrect enums | 8 fixed | ✅ Fixed |
| ghz_authenticated_fixed.sh | 8 incorrect enums | 8 fixed | ✅ Fixed |
| ghz_quick_test.sh | 2 incorrect enums | 2 fixed | ✅ Fixed |
| ghz_quick_auth_test.sh | 0 incorrect enums | 0 changes | ✅ Already correct |

**Total Fixes**: 18 enum value corrections across 3 files

## Verification

All scripts verified using automated checking:
```bash
✅ All ghz scripts use correct proto enum format!

Correct enum values found:
  "side": "ORDER_SIDE_BUY"
  "side": "ORDER_SIDE_SELL"
  "side": "{{randomString \"ORDER_SIDE_BUY\" \"ORDER_SIDE_SELL\"}}"
  "order_type": "ORDER_TYPE_LIMIT"
  "order_type": "ORDER_TYPE_MARKET"
```

## Testing

Scripts can now be executed without proto enum errors:

```bash
# Quick test (1 request)
./tests/load_tests/ghz_quick_auth_test.sh

# Quick load test (100 requests)
./tests/load_tests/ghz_quick_test.sh

# Full authenticated load test (4 scenarios)
./tests/load_tests/ghz_authenticated.sh
```

## Impact

- **Before**: ghz would fail with proto enum parsing errors
- **After**: All ghz load tests execute correctly with proper proto enum validation
- **Production Ready**: Load tests now match production proto definitions exactly
