 Where the denominator is the sum of the weights (e.g., for a 3-period LWMA, the weights are 3, 2, 1, and the sum is 6).
 
+### TMA (Triangular Moving Average)
+
+The TMA is a double-smoothed moving average that gives the most weight to the data in the middle of its lookback period. It is extremely smooth and is best used as a long-term trendline or cyclical centerline, not for fast signals. It is calculated by taking an SMA of an SMA.
+
+1. $\text{SMA}_{1_t} = \text{SMA}(P, \text{Ceiling}(\frac{N + 1}{2}))_t$
+2. $\text{TMA}_t = \text{SMA}(\text{SMA}_1, \text{Floor}(\frac{N + 1}{2}))_t$
+
+### DEMA (Double Exponential Moving Average)
+
+Developed by Patrick Mulloy, the DEMA is not a simple double-smoothed EMA. It is a lag-reduction technique that combines a single EMA and a double EMA to create a more responsive moving average.
+
+1. $\text{EMA}_{1_t} = \text{EMA}(P, N)_t$
+2. $\text{EMA}_{2_t} = \text{EMA}(\text{EMA}_1, N)_t$
+3. $\text{DEMA}_t = (2 \times \text{EMA}_{1_t}) - \text{EMA}_{2_t}$
+
+### TEMA (Triple Exponential Moving Average)
+
+Also developed by Patrick Mulloy, the TEMA is an even more advanced lag-reduction technique that uses a triple-smoothing process to create an extremely responsive moving average that stays very close to the price.
+
+1. $\text{EMA}_{1_t} = \text{EMA}(P, N)_t$
+2. $\text{EMA}_{2_t} = \text{EMA}(\text{EMA}_1, N)_t$
+3. $\text{EMA}_{3_t} = \text{EMA}(\text{EMA}_2, N)_t$
+4. $\text{TEMA}_t = (3 \times \text{EMA}_{1_t}) - (3 \times \text{EMA}_{2_t}) + \text{EMA}_{3_t}$

 ## 3. MQL5 Implementation Details
 
-This indicator is a prime example of our modular and efficient design philosophy.

 * **Universal Calculation Engine (`MovingAverage_Engine.mqh`):**
-    The entire calculation logic for all four MA types is encapsulated within a single, reusable engine file. This centralized approach eliminates code duplication, simplifies maintenance, and ensures mathematical consistency across our entire indicator suite.
+    The entire calculation logic for all **seven** MA types is encapsulated within a single, reusable engine file. This centralized approach eliminates code duplication and simplifies maintenance.
 
-* **User-Selectable Type via Enum:** The indicator uses an `input ENUM_MA_TYPE` parameter, which creates a user-friendly dropdown menu in the settings window. The user's selection is passed directly to the universal engine, which then performs the correct calculation.
+* **Efficient EMA Calculation:** The engine uses a dedicated `CalculateEMA` helper function. This function is called recursively to efficiently build the DEMA and TEMA without rewriting the core EMA logic.
 
-* **Object-Oriented Design (Inheritance):**
-    A `CMovingAverageCalculator` base class and a `CMovingAverageCalculator_HA` derived class are used to cleanly separate the logic for standard and Heikin Ashi price sources. The child class only overrides the data preparation method, inheriting the entire calculation logic.
