The fastest of the traditional moving average family — three EMA passes combined into a single line that lags real price by almost nothing. Use when reaction speed dominates every other consideration.
EMA vs DEMA vs TEMA — three speeds at the same period
What it measures
- Trend direction with minimal lag. Tracks price more closely than any other classical moving average at the same period.
- Momentum changes earlier than DEMA or EMA. The slope flips first.
- Smoothed enough to be a reference line. Faster than raw price but still produces a clean curve.
Formula
How AlgoLift computes it
TEMA = (3 × EMA1) − (3 × EMA2) + EMA3
Where EMA1 is the EMA of price, EMA2 is the EMA of EMA1, and EMA3 is the EMA of EMA2 — all at the same period. The three-term correction cancels nearly all of the lag introduced by the underlying smoothing.
The math extends the same idea behind DEMA: subtract out the smoothing artifacts that come from nesting EMAs. Where DEMA cancels first-order lag, TEMA cancels second-order lag too — at the cost of amplifying high-frequency noise.
Inputs in AlgoLift
| Setting | Default | Range | Notes |
|---|---|---|---|
| Period | 14 | 2–500 | Lookback in bars. TEMA's aggressive smoothing means very short periods (3–7) become viable where they'd be unusable on EMA. |
Recommended periods
- 5–9 (fast): Short-term execution. TEMA(5) reacts almost as fast as raw price changes but with a recognizable line.
- 14 (default): Intraday day-trading. Balanced speed/smoothness.
- 20–30: Slower reference. Most users prefer EMA at these periods because TEMA's extra reactivity becomes noise rather than signal.
Outputs in AlgoLift
| Handle | Type | Plotted | Notes |
|---|---|---|---|
| TEMA | Numeric | Always | The TEMA line. |
| Slope | Numeric | On select | Changes direction very quickly — useful for early momentum reversal detection, dangerous in chop. |
TEMA node — default state
How to read it
- Price above TEMA: Up-state, confirmed faster than any other moving average.
- Price below TEMA: Down-state.
- TEMA slope flip: Often the earliest possible "trend changed" signal you can extract from a moving average. Also the earliest possible false signal.
- TEMA crossover with EMA or SMA at the same period: A common diagnostic — when TEMA leads EMA by a wide margin, the trend is genuinely fast.
TEMA reacts faster than anything else in the moving-average family. Use it when lag is the binding constraint on your strategy. Don't use it when you need stability — that's what SMA is for.
Best in / worst in
Best in very-short-timeframe execution (sub-5m bars) and on instruments with sharp directional moves. Pairs well with breakout strategies where catching the initial impulse matters more than filtering false starts.
Worst in sideways markets, on choppy instruments, and as a primary trend filter. The same reactivity that makes TEMA useful for execution makes it useless for regime classification.
Three setups
1. TEMA slope reversal entry
Skip the value, trade only the slope flip.
- Long: TEMA(9) slope was negative for 3+ consecutive bars AND just turned positive.
- Short: Symmetric.
This is essentially a momentum reversal signal. The bar-count requirement filters out the most common false signals.

2. TEMA / EMA divergence
When the fast and slow versions disagree significantly, the market is in a strong directional move.
- Long: TEMA(14) is more than 0.5% above EMA(14) — strong upside momentum.
- Short: TEMA(14) is more than 0.5% below EMA(14) — strong downside momentum.
Use as a trend-strength filter rather than a primary signal.
3. TEMA fast execution + slow EMA filter
The classic "TEMA where speed matters, EMA where regime matters" pattern.
- Long entry: Price crosses above TEMA(9) AND price > EMA(50).
- Short entry: Price crosses below TEMA(9) AND price < EMA(50).
The slow EMA prevents most false TEMA signals; the fast TEMA gives entries earlier than an EMA-only system would.
Advanced patterns in AlgoLift
TEMA-triggered scale-in entries. Use a slow moving average (EMA or SMA) crossover as your initial entry, then use TEMA's faster slope flips to trigger Scaled Entry additions to winning positions. The pattern catches the slow setup and presses the position when fast confirmation arrives.
TEMA in a Cluster. TEMA + slow trend filter + ATR-based stop forms a complete short-term execution kit. Save the combination as a Cluster once and drop it into every short-horizon strategy you build.
Common mistakes
- Using TEMA as a regime filter. It's far too reactive — a single sharp counter-bar flips the trend signal. Use SMA(200) or EMA(200) for regime, TEMA for execution.
- Long periods on TEMA. TEMA(200) defeats the purpose. If you want a slow average, use one. TEMA earns its compute cost only at short periods.
- No cooldown on TEMA crossovers. The faster the average, the more crossovers occur, the worse machine-gun trading becomes. Always wire a Cooldown.
