Summary
The Hull Moving Average (HMA) is a trend-following indicator designed to react faster than a normal moving average while staying smooth. In Profectus.AI, you do not always need a built-in indicator block for every indicator. Many indicators are just formulas, and formulas can be recreated with Formula blocks and Variables.
This article shows the logic behind building an HMA-style indicator inside Profectus.AI and using it as part of your trading bot.
The Core Idea
An indicator is usually just math.
If you know the calculation behind an indicator, you can often rebuild it inside Profectus.AI by using:
Inputs for adjustable settings, such as the HMA period
Variables to store calculated values
Formula blocks to calculate the indicator step by step
Trade Rule blocks to use the final value in your strategy
For the Hull Moving Average, the goal is simple:
Calculate the HMA value of the last closed candle
Calculate the HMA value of the candle before that
Compare both values
Decide if the HMA is moving up or down
What the HMA Tells You
In the example from the video:
If the latest HMA value is higher than the previous HMA value → the HMA is rising
If the latest HMA value is lower than the previous HMA value → the HMA is falling
This can be translated into a simple trend signal:
HMA rising = bullish / green
HMA falling = bearish / red
You can then use this signal in your trading logic.
Example Setup
Let’s say you want to use the HMA as a simple trend filter.
Create these variables:
Variable | Purpose |
| Stores the HMA value of the last closed candle |
| Stores the HMA value of the candle before that |
| Stores whether the HMA is rising or not |
You can also create an input:
Input | Purpose |
| Lets you adjust the HMA period in MetaTrader 5 |
Step 1 — Calculate the HMA Value of Candle ID 1
Start with a Run per Candle block.
Then add a Formula block that calculates the HMA value for Candle ID 1, which is the last fully closed candle.
Store the result in:
HMA_Candle_1
This value represents the current confirmed HMA value.
Step 2 — Calculate the HMA Value of Candle ID 2
Add a second Formula block.
This one calculates the same HMA formula, but for Candle ID 2, which is the candle before the last closed candle.
Store the result in:
HMA_Candle_2
Now your bot has two HMA values it can compare.
Step 3 — Compare Both HMA Values
Add a Trade Rule block:
HMA_Candle_1 > HMA_Candle_2
If this is true, the HMA is rising.
Then use a Modify Variables block to set:
HMA_Green = 1
If the condition is false, set:
HMA_Green = 0
This turns the HMA direction into a simple value your bot can use.
Step 4 — Use the HMA in a Strategy
Once HMA_Green exists, you can use it like any other condition.
Example:
Add Run per Candle
Add Trade Rule
Check if:
HMA_Green = 1
If true, trigger a Buy Now block
This means:
Every new candle, if the HMA is rising, the bot is allowed to buy.
This is only a simple example. In a real strategy, you would usually combine this with additional filters, risk settings, and trade management.
Why This Matters
The HMA example teaches a bigger lesson:
You are not limited to the indicators already visible in the platform.
If an indicator can be broken down into a formula, you can often recreate it with:
Formula blocks
Variables
Inputs
Trade Rules
That means you can build custom indicators, modify them, test different settings, and use the output directly inside your strategy logic.
Make It Your Own
You can experiment with:
Changing the HMA period
Running it on another timeframe
Using it as a trend filter instead of a direct entry
Combining it with price action patterns
Allowing buys only when HMA is rising
Allowing sells only when HMA is falling
Export the bot after each change and test it in MetaTrader 5 Visual Mode to confirm the logic behaves as expected.
Conclusion
The Hull Moving Average is a good example of how custom indicators can be rebuilt inside Profectus.AI. Instead of waiting for every indicator to exist as a prebuilt block, you can recreate indicator logic yourself using Formula blocks and Variables.
If you can understand the formula, you can turn it into blocks.
