Hello peeps,
I have been busy working on indicator that will power an EA
The indicator has gone thru 26 iterations and the EA has gone thru 16 iterations -- a lot of hard work using three different AIs working around the clock on improvements with hundreds of Agents doing the heavy lifting.
Here is the
XU Candles v1.26 indicator for your perusa
Here is the ex5 code -- its still a work in progress but reports are good.
Here is the deep dive report on the indicator

## Code Quality Assessment
### Strengths
1. **Clean Architecture**
- Clear separation between confirmed bar and forming bar logic
- Helper functions are focused and single-purpose
- State management via `BrokerState` struct
2. **Robust Error Handling**
- Invalid handle recovery
- Data validation with graceful skips
- Safe array access checks
3. **Performance Optimizations**
- Throttling prevents UI spam
- Only recalculates changed bars
- Efficient DSEMA state reuse
4. **User Experience**
- Configurable chart mode
- Visual trend indication
- Clean object management

## Key Implementation Details
### DSEMA Instance Mapping
| Instance | Period | idx1 | idx2 | Buffer |
|----------|--------|------|------|--------|
| 0 | 60 | 0 | 1 | d60 |
| 1 | 80 | 2 | 3 | d80 |
| 2 | 500 | 4 | 5 | d500 |
| 3 | 600 | 6 | 7 | d600 |
**Formula:** `idx1 = instance * 2`, `idx2 = idx1 + 1`
### Confirmed vs Forming Bar
| Aspect | Confirmed Bar | Forming Bar |
|--------|---------------|-------------|
| Index | `0` to `rates_total-2` | `rates_total-1` |
| Calculation | `CalculateDSEMA` | `CalculateDSEMA_Preview` |
| Persistence |

## For EA Developers
### Reading Indicator Values
```cpp
// Get indicator handle
int handle = iCustom(_Symbol, _Period, "XU_Sovereign_Indicator_v1.26");
// Copy buffers
double d60[], d500[];
CopyBuffer(handle, 5, 0, 3, d60); // Buffer 5 = d60
CopyBuffer(handle, 7, 0, 3, d500); // Buffer 7 = d500
// For trading decisions - use CONFIRMED bar (index 1)
// Index 0 = forming bar (unstable)
// Index 1 = last confirmed bar (stable)
bool isBullish = d60[1] > d500[1];
// For visualization - can use forming bar (index 0)
double currentD60 = d60[0];
```
### Buffer Index Reference
| Index | Buffer | Content |
|-------|--------|---------|
| 0 | cO | Candle Open |
| 1 | cH | Candle High |
| 2 | cL | Candle Low |
| 3 | cC | Candle Close |
| 4 | cColor | Candle Color (0=Blue/Bull, 1=Pink/Bear) |
| 5 | d60 | DSEMA 60 |
| 6 | d80 | DSEMA 80 |
| 7 | d500 | DSEMA 500 |
| 8 | d600 | DSEMA 600 |
| 9 | scout | Scout line (d80 + 2xATR) |
| 10 | king | King line (d500 + 3.5xATR) |

## Recommended Settings
### For Trading
```
InpUseBarCloseMode = true // Stable, non-repainting
InpDetectGaps = true // Reset on gaps
InpValidateData = true // Ignore bad ticks
InpThrottleMs = 250 // Balanced UI refresh
InpForceLineMode = true // Clean chart
```
### For Analysis/Backtesting
```
InpUseBarCloseMode = false // Real-time updates
InpDetectGaps = true
InpValidateData = true
InpThrottleMs = 100 // Faster updates
InpForceLineMode = false // Keep candles visible
```
