Hull Suite draws one smoothed trend band on MT4 and MT5, in your choice of three Hull variations, coloured by its own direction.
It is the simplest tool in this range and the one most likely to be misused, so this page spends its time on what it is not.
Three variations, one switch
HMA is the standard Hull: a weighted average of twice the half-length WMA minus the full-length WMA, smoothed again over the square root of the length. Fast for its smoothness, which is the whole reason Hull exists.
EHMA does the same construction with exponential averages throughout. Slightly smoother, slightly slower to turn.
THMA uses a three-way weighted combination and is called at half your length, so it responds on a shorter effective window than the number in the box suggests.
Length defaults to 55. The source comments the two settings people actually use: 55 for swing work, and 180 to 200 if you want the band to behave as slow floating support and resistance rather than as a trend signal. Those are very different tools from the same file, and the second one is worth trying before you decide the indicator is too slow.
Length multiplier scales whatever you set, which is the convenient way to test 1.5× or 0.5× without recomputing the number in your head.
The colour is a two-bar comparison
The band is green when the Hull line is above where it was two bars ago, and red when it's below.
That's the entire trend rule. Not price against the line, not a crossover, not a slope threshold. The line against its own recent self.
It's worth knowing because it explains the behaviour you'll see immediately: the colour flips shortly after the line's own turn, and the line's own turn comes after price has already moved. On the gold chart above the band goes red near the top, several bars after the high. That is the design working, not the indicator failing.
Show as a Band? draws the fill between the line and its shifted copy. Turn it off and you get the line alone, which is easier to read at small chart sizes and loses the visual weight that makes the band useful in the first place.
Alerts are on out of the box
This one is unusual in the range: Notification type ships as Alert, not as none. Two switches, one for turning up and one for turning down, both enabled.
So it will talk to you as soon as you attach it. That's a reasonable default for a slow trend tool that changes colour a handful of times a week, and it will be a problem if you put it on twenty charts.
The MT5 build adds email and Telegram routing; the MT4 build alerts through the terminal.
| Ordinary moving average | This | |
|---|---|---|
| Variations | One | HMA, EHMA and THMA from one switch |
| Trend rule | Price crossing the line | The line against its own value two bars back |
| Display | A line | A filled band, or a line if you prefer |
| Alerts | Usually none | On by default, one switch per direction |
| Intended lengths | Whatever you set | 55 for swings, 180 to 200 for slow support and resistance |
Where it's weak
It lags, by construction, and no setting removes that. A 55-period Hull turns after the market does. If you need something early, this is the wrong tool and a shorter length will give you noise rather than earliness.
The two-bar colour rule is crude. One flat stretch is enough to flip the colour and flip it back, so in a sideways market the band alternates without anything having happened. There is no slope threshold and no confirmation count.
No signals, no levels, no structure. It draws a band. There are no arrows, no entries, no stops and nothing that marks a specific bar.
THMA's length is halved internally. Selecting THMA with a length of 55 runs the calculation on an effective window of about half that, so the three variations are not directly comparable at the same setting. Compare them by eye rather than by the number.
No indicator buffers you'd want to build on beyond the band itself. The plotted output is the line and its shifted copy for the fill. iCustom will give you those, and there is no separate trend-state buffer, so an EA has to compare the two values itself.
The two platforms are not identical builds. MT5 is the newer, faster implementation and carries the full notification block including Telegram. MT4 is the earlier build with terminal alerts and its own colour and fill inputs. The twelve settings that determine the line are the same on both and the band you see matches; the plumbing around it does not.
Questions you'll have
Does Hull Suite repaint? The current bar's value moves while the bar forms, the way any moving average does. Closed bars are stable and the colour of a past segment does not change.
Why does it turn after the top? Because the colour compares the Hull line to itself two bars earlier, and the line itself is a 55-period average. It is a trend follower. Turning at the extreme is not something it attempts.
Which variation should I use? HMA unless you have a reason. EHMA if you want it slightly smoother, THMA if you want it faster, remembering that THMA effectively halves your length.
What length should I use? 55 for swing trading. 180 to 200 if you want it as slow floating support and resistance, which is a genuinely different way to use the same indicator.
Why is it alerting me straight away? Alerts ship on in this one, with both directions enabled. Set Notification type to none if you'd rather it stayed quiet.
Can an EA read it? Yes, the band's two lines are plotted buffers. There is no separate trend flag, so compare the current value against the older one yourself.
Are MT4 and MT5 the same? The calculation and its twelve settings are. MT5 is a newer, faster build with email and Telegram routing; MT4 alerts through the terminal and exposes its own colour and fill inputs.
Best timeframe? H1 and H4 at length 55. On M15 the lag is a larger share of the move you're trying to catch.
