Standard moving averages force you into a compromise. Pick an EMA and you get speed but deal with jittery lines that react to every minor price fluctuation. Switch to an SMA and the line smooths out, but it lags so far behind that signals arrive late. Tim Tillson solved this problem in 1998 when he published the T3 Moving Average – a triple-smoothed exponential moving average that manages to be smoother than an EMA while producing less lag than an SMA of the same period.
The T3 isn’t built into MetaTrader 4, which is why most retail traders have never tried it. That’s unfortunate, because on noisy pairs and choppy timeframes where standard MAs generate constant false signals, the T3 genuinely outperforms. In this review, we’ll cover how it works, the best settings for different trading styles, and a practical crossover strategy you can apply today.
What is the T3 Moving Average Indicator?
The T3 Moving Average was developed by Tim Tillson and introduced in the January 1998 issue of Technical Analysis of Stocks & Commodities magazine. Unlike a standard EMA that applies exponential weighting once, the T3 runs price data through six cascaded EMA calculations – essentially smoothing the data three times over.
What makes the T3 unique is its “volume factor” parameter (often labeled “v-factor” or simply “b”), which controls how aggressively the smoothing operates. At the default value of 0.7, the T3 produces a line that hugs price closely during strong trends but stays remarkably flat during sideways chop. Lowering the volume factor toward 0.0 makes the T3 behave more like a conventional EMA. Pushing it toward 1.0 increases the smoothing effect dramatically, though values above 0.9 can cause overshoot.
The underlying math involves a generalized DEMA (double exponential moving average) formula applied in three layers. You don’t need to understand the calculus to use it effectively, but the result is a moving average that reacts to genuine trend changes while filtering out the noise that plagues simpler alternatives.
How the T3 Moving Average Works on MT4
When you apply the T3 to a chart, the first thing you’ll notice is how clean the line looks compared to a standard moving average of the same period. Where an EMA might zig-zag through choppy price action, the T3 glides through it in a smooth curve.
Trend identification works the same way as any moving average. Price above the T3 line indicates bullish bias; price below indicates bearish. The difference is the quality of that signal. Because the triple smoothing eliminates most of the minor fluctuations, the T3 changes slope less frequently than an EMA, which means fewer false direction changes.
The T3 is particularly effective on pairs known for noisy price action – GBP/JPY, GBP/NZD, and most cross pairs where whipsaws regularly shake traders out of valid positions. On these instruments, a standard 20 EMA might change direction several times during what is actually a single sustained move. The T3 with the same period tends to hold its direction through those whipsaws.
Key Features
- Non-repainting: Once a candle closes, the T3 value is permanent and will never change
- Adjustable volume factor (0.0 to 1.0) lets you fine-tune the smoothing-responsiveness balance
- Significantly smoother than EMA and DEMA at equivalent period settings
- Less lag than SMA, making it a genuine “best of both worlds” moving average
- Works on all timeframes from M1 to Monthly
- Lightweight custom indicator with minimal CPU and memory usage
Best Settings for T3 Moving Average
The volume factor is what sets the T3 apart from other moving averages. Here are tested configurations for each trading style:
| Parameter | Scalping (M1-M5) | Day Trading (M15-H1) | Swing Trading (H4-D1) |
|---|---|---|---|
| T3 Period | 8 | 14 | 21 |
| Volume Factor | 0.8 | 0.7 | 0.6 |
| Applied Price | Close | Close | Close |
| Slow MA (for crossover) | 21 T3 (v=0.8) | 50 EMA | 50 EMA |
Volume factor guidance: On volatile pairs like GBP/JPY, increase the volume factor by 0.1 above the defaults listed above. On smooth-trending majors like EUR/USD, the defaults work well as-is. If you’re getting too many signals, raise it. If signals feel delayed, lower it.
Recommended starting point: Apply a 14-period T3 with a volume factor of 0.7 on the H1 chart alongside a 50 EMA. This pairing gives you the T3’s smooth trend line for direction combined with the EMA as a dynamic support/resistance reference.
Pros and Cons
| Pros | Cons |
|---|---|
| Noticeably smoother line reduces false signals in choppy markets | Not built into MT4 – requires downloading and installing a custom indicator |
| Volume factor provides fine control no other MA offers | Extra parameter (volume factor) adds a learning curve versus simple MA types |
| Less lag than SMA while being smoother than EMA | Can overshoot price during sharp reversals at high volume factor settings |
| Excellent on noisy pairs where standard MAs generate whipsaws | Less widely discussed online, meaning fewer community resources and presets |
How to Install T3 Moving Average Indicator on MT4
Since the T3 is not built into MetaTrader 4, you’ll need to install it as a custom indicator. Here’s how:
Step 1: Download the T3 Moving Average .ex4 file from the download section below.
Step 2: Open your MT4 terminal. Click File > Open Data Folder in the top menu.
Step 3: Navigate to the MQL4 > Indicators folder. Copy the downloaded T3 .ex4 file into this folder.
Step 4: Go back to MT4. Right-click anywhere in the Navigator panel (left side) and select Refresh. Alternatively, close and reopen MT4.
Step 5: In the Navigator panel, expand Custom Indicators, locate T3 Moving Average, and drag it onto your chart. In the settings window, set your desired period and volume factor (start with period 14 and volume factor 0.7), then click OK.
Tip: If the indicator doesn’t appear after refreshing, make sure you placed the file in the correct folder. The path should be MQL4/Indicators, not MQL4/Experts or any subfolder.

Trading Strategy Using T3 Moving Average
This T3 crossover strategy works well on the H1 and H4 timeframes by combining the T3’s smooth trend reading with a standard EMA for crossover timing:
Setup: Apply a 14-period T3 (volume factor 0.7, blue) and a 50-period EMA (red) to your chart.
Buy Signal:
1. The T3 crosses above the 50 EMA
2. Wait for price to pull back toward the T3 line without breaking below the 50 EMA
3. Enter long when a bullish candle closes above the T3 after the pullback
4. Confirm that the T3 line is still sloping upward at the time of entry
Sell Signal:
1. The T3 crosses below the 50 EMA
2. Wait for price to rally back toward the T3 line without breaking above the 50 EMA
3. Enter short when a bearish candle closes below the T3 after the pullback
4. Confirm that the T3 line is still sloping downward at the time of entry
Stop Loss: Place the stop 5-10 pips beyond the 50 EMA at the time of entry.
Take Profit: Aim for a minimum 1:1.5 risk-reward ratio. For a trailing approach, move your stop to breakeven when price reaches 1:1, then trail the stop along the T3 line and exit when price closes on the wrong side of it.
The advantage of using the T3 instead of a fast EMA in this setup is fewer false crossovers. During consolidation periods, a 14 EMA will cross above and below the 50 EMA repeatedly, generating a string of losing trades. The T3’s smoother trajectory means it only crosses when a more meaningful trend shift is underway.
T3 Moving Average vs Hull Moving Average (HMA)
Both the T3 and the Hull Moving Average were designed to solve the same fundamental problem – reducing lag without sacrificing smoothness. They take different approaches to get there:
| Feature | T3 Moving Average | Hull Moving Average (HMA) |
|---|---|---|
| Developer | Tim Tillson (1998) | Alan Hull (2005) |
| Method | Triple-smoothed EMA with volume factor | Weighted MA with square root period |
| Smoothness | Very smooth – minimal noise | Smooth, but can show minor ripples |
| Lag | Low – less than SMA, comparable to EMA | Very low – fastest of all smoothed MAs |
| Customization | Volume factor gives fine-grained control | Period only – no equivalent tuning parameter |
| Overshoot Risk | Moderate at high volume factors | Higher – can lead price during sharp moves |
| Best For | Noisy pairs needing clean trend lines | Fast trend detection where minimal lag is priority |
Verdict: Choose the T3 when you’re trading volatile, noisy pairs and want the cleanest possible trend line with adjustable smoothing. Choose the HMA when your priority is speed and you need the earliest possible signal on trending pairs. Many traders apply both on the same chart – the HMA for entry timing and the T3 for trend confirmation.
Frequently Asked Questions
Is the T3 Moving Average indicator free?
Yes. The T3 Moving Average indicator is available as a free download here on ForexOBroker. Unlike the standard moving average, the T3 is not built into MT4, so you’ll need to install the custom .ex4 file into your platform.
Does the T3 Moving Average indicator repaint?
No. Once a candle closes, the T3 value for that bar is locked in permanently. The only movement you’ll see is on the current unclosed candle, which recalculates with each tick – this is standard behavior for all moving averages and does not constitute repainting.
What is the best volume factor for T3?
The default volume factor of 0.7 works well for most setups. Use lower values (0.5-0.6) if you want faster response at the cost of less smoothing. Use higher values (0.8-0.9) on noisy pairs or lower timeframes where extra smoothing helps filter out false signals. Avoid going above 0.9, as the line can begin overshooting price reversals.
Can I use the T3 Moving Average on MT5?
Yes, but you need an MT5-compatible version of the indicator file (.ex5 format). The MT4 .ex4 file will not work on MT5. The T3 calculation itself is identical on both platforms.
What pairs does T3 Moving Average work best on?
The T3 shines on pairs with noisy, erratic price action where standard MAs generate excessive false signals – GBP/JPY, GBP/NZD, EUR/GBP, and most cross pairs. It also works well on majors like EUR/USD and GBP/USD, though on cleaner-trending pairs the advantage over a standard EMA is less dramatic.
