# StratForge Technical Indicators Catalog

> Comprehensive documentation of the 138+ technical indicators available in the StratForge C++23 backtesting engine.

StratForge (`nonabt::`) is a high-performance C++23 library for quantitative trading, offering over 138 indicators with sub-microsecond computation speeds. It is designed to be 100x to 1000x faster than Python-based alternatives like `backtrader` or `pandas-ta`.

## High-Volume Indicators (Pilot Collection)

### 1. Relative Strength Index (RSI)
**Mathematical Formula**: `RSI = 100 - [100 / (1 + RS)]`, where `RS = Average Gain / Average Loss`.
**Parameters**:
- `period` (default: 14): The lookback period for calculation.
- `movav` (default: `Smoothed`): Moving average type (`Smoothed`, `Simple`, `Exponential`).

**C++23 API**:
```cpp
#include <nonabt/indicators/rsi.hpp>
auto rsi = std::make_unique<nonabt::RSI>(data().close(), 14);
```

**Strategy Snippet**:
```cpp
if (rsi->line()[0] < 30) {
    buy(100); // Buy when oversold
} else if (rsi->line()[0] > 70) {
    sell(100); // Sell when overbought
}
```

---

### 2. Moving Average Convergence Divergence (MACD)
**Mathematical Formula**: `MACD Line = (12-day EMA - 26-day EMA)`. `Signal Line = 9-day EMA of MACD Line`.
**Parameters**:
- `fast_period` (default: 12)
- `slow_period` (default: 26)
- `signal_period` (default: 9)

**C++23 API**:
```cpp
#include <nonabt/indicators/macd.hpp>
auto macd = std::make_unique<nonabt::MACD>(data().close(), 12, 26, 9);
```

**Strategy Snippet**:
```cpp
if (macd->macd()[0] > macd->signal()[0]) {
    buy(100); // Bullish crossover
} else if (macd->macd()[0] < macd->signal()[0]) {
    sell(100); // Bearish crossover
}
```

---

### 3. Bollinger Bands (BBANDS)
**Mathematical Formula**: `Middle Band = SMA`. `Upper/Lower Bands = SMA +/- (k * StdDev)`.
**Parameters**:
- `period` (default: 20)
- `dev` (default: 2.0): Standard deviation multiplier.

**C++23 API**:
```cpp
#include <nonabt/indicators/bollinger.hpp>
auto bbands = std::make_unique<nonabt::BBANDS>(data().close(), 20, 2.0);
```

**Strategy Snippet**:
```cpp
if (data().close()[0] < bbands->bot()[0]) {
    buy(100); // Price below lower band
} else if (data().close()[0] > bbands->top()[0]) {
    sell(100); // Price above upper band
}
```

---

### 4. Average True Range (ATR)
**Mathematical Formula**: `ATR = Moving Average of True Range`.
**Parameters**:
- `period` (default: 14)

**C++23 API**:
```cpp
#include <nonabt/indicators/atr.hpp>
auto atr = std::make_unique<nonabt::ATR>(14);
```

---

### 5. Stochastic Oscillator (STOCH)
**Mathematical Formula**: `%K = 100 * (Close - Lowest Low(n)) / (Highest High(n) - Lowest Low(n))`. `%D = SMA(%K, 3)`.
**Parameters**:
- `period` (default: 14): Lookback for %K.
- `period_dfast` (default: 3): Smoothing for %D.
- `period_dslow` (default: 3): Smoothing for slow %D.

**C++23 API**:
```cpp
#include <nonabt/indicators/stochastic.hpp>
auto stoch = std::make_unique<nonabt::STOCH>(14, 3, 3);
```

---

### 6. Ichimoku Cloud (ICHIMOKU)
**Mathematical Formula**: `Tenkan-sen = (Highest High + Lowest Low) / 2` over 9 periods. `Kijun-sen` = same over 26 periods. `Senkou Span A = (Tenkan + Kijun) / 2` displaced 26 periods forward. `Senkou Span B` = (52-period high+low)/2 displaced forward.
**Parameters**:
- `tenkan` (default: 9): Conversion line period.
- `kijun` (default: 26): Base line period.
- `senkou` (default: 52): Leading span B period.

**C++23 API**:
```cpp
#include <nonabt/indicators/ichimoku.hpp>
auto ichi = std::make_unique<nonabt::ICHIMOKU>(9, 26, 52);
```

---

### 7. On-Balance Volume (OBV)
**Mathematical Formula**: `OBV = OBV_prev + Volume` if Close > Close_prev; `OBV_prev - Volume` if Close < Close_prev; unchanged if equal.
**Parameters**: None (uses close price and volume).

**C++23 API**:
```cpp
#include <nonabt/indicators/obv.hpp>
auto obv = std::make_unique<nonabt::OBV>(data().close(), data().volume());
```

---

### 8. Exponential Moving Average (EMA)
**Mathematical Formula**: `EMA = [Price(t) * k] + [EMA(y) * (1 - k)]`, where `k = 2 / (n + 1)`.
**Parameters**:
- `period` (default: 20): Smoothing period.

**C++23 API**:
```cpp
#include <nonabt/indicators/ema.hpp>
auto ema = std::make_unique<nonabt::EMA>(data().close(), 20);
```

---

### 9. Commodity Channel Index (CCI)
**Mathematical Formula**: `CCI = (Typical Price - SMA(TP, n)) / (0.015 * Mean Deviation)`. `Typical Price = (High + Low + Close) / 3`.
**Parameters**:
- `period` (default: 20)

**C++23 API**:
```cpp
#include <nonabt/indicators/cci.hpp>
auto cci = std::make_unique<nonabt::CCI>(20);
```

---

### 10. Heikin Ashi (HEIKINASHI)
**Mathematical Formula**: `HA Close = (Open + High + Low + Close) / 4`. `HA Open = (HA Open_prev + HA Close_prev) / 2`. `HA High = max(High, HA Open, HA Close)`. `HA Low = min(Low, HA Open, HA Close)`.
**Parameters**: None (transforms existing OHLC data).

**C++23 API**:
```cpp
#include <nonabt/indicators/heikinashi.hpp>
auto ha = std::make_unique<nonabt::HEIKINASHI>();
```

## Routing Note

WordPress SEO pages under `/quantnexus/indicators/{slug}/` now resolve against the full 138-item JSON catalog, including underscore-based slugs such as `MINUS_DI`, `PLUS_DI`, and `RSI_SAFE`.

Users can use the clean hyphenated URL form while the internal catalog keeps the original StratForge slug names.
