Welcome to the next Stonehill Forex Indicator Study. This research represents an investigative look into how and why some indicators work and some don’t work as well.
Increased Efficiency
We introduce indicators not included with the MT4 platform to find more efficient indicators which may yield superior results. Some indicators may have alternate beginnings, but they can be amazing when they’re used for trading.
Our Next Indicator Choice is…
The Kalman Filter is our next confirmation indicator we’ll discuss. This indicator has similar qualities as the McGinley Dynamic Indicator, whereby it is considered “adaptive” – meaning that the math behind the indicator adjusts to the volatility of the market. There are massive amounts of work associated with this indicator which are quite impressive. If you’d like to read a recent (and very comprehensive) paper on the “Kalman Filter Approach”, click HERE.
What’s interesting about this indicator is that it works in a two-step process. The first step is called extrapolation, or prediction. Market data is sometimes called “noisy”, meaning that it doesn’t always move in a smooth, predictable way. The first step takes this data and predicts what will happen. The second step of the process is the update, or correction part. This means the current price is compared to the past prediction and the new value becomes the current position of the line on your chart.
Follow That…Thing!
Another way to visualize what the Kalman Filter does is estimate the trajectory of a moving object…whether it be a car, plane, spaceship…or a moving average!
In essence, this indicator takes market activity into account to show a smoother, more responsive, moving average line. This doesn’t mean that lag is removed altogether, it means that this indicator’s reaction to the market is faster by applying the two-step method.
Original Thought
The original concept and math was developed by Rudolf Kálmán in 1960. Its use began in the aerospace industry; helping solve navigation and guidance problems calculated by old IBM 704 computers. It’s use in the trading industry began in the 1990s.
Confirmation Indicator
The Kalman Filter presents as The “confirmation indicator” which falls into the category of the indicators that serve as an initial checkpoint after the baseline indicator. It is an on-chart indicator, overlaying price (see snapshot below). These concepts are explained in great detail in the Stonehill Forex Advanced Course HERE.
Advantages
* Easy to see signals
* Better representation of market dynamics due to adaptive nature.
* Reduced lag as market conditions change
* Smooths out market noise
* Simple, Yet Elegant
Below is a screenshot of what the indicator looks like on the daily time frame. Note that we’ve changed the color of the candles to white to remove any emotional bias and that only the indicator is prominent.
How We Use It
The signal occurs on the opening of the period following the change of color from orange to turquoise, or turquoise to orange. Let’s review the highlighted marks on the picture below to understand what they mean.
Signals
Long = Line turns from orange to turquoise.
Short = Line turns from turquoise to orange.
Settings
The settings include; Mode, K, Sharpness, and Draw_begin. The default settings are; 6, 1.0, 1.0, and 250. These are the settings and default values of the version we have available for download on the resource page. Some versions have slightly different default values. Before we take a closer look, I’ll explain what each parameter represents.
Mode: The type of moving average used for calculations: Simple, Exponential, Weighted, Double Exponential, Triple Exponential, Lease square Moving Average, etc. Settings range from 0-6.
K: Also known as the Kalman Factor. The range starts at 0.1 and extends as high as you want it to go. The smaller the number, the longer (bigger) the curve. The bigger the number, the more closely the curve follows price.
Sharpness: This is for calculating error minimization. It functions similarly as the Kalman Factor. The smaller the number, the less “sharp” the curve and the larger the number, the quicker it reacts to price change.
draw_begin: The number of periods in history the indicator begins to draw.
Testing…Testing…Testing
Remember, comprehensive analysis is strongly suggested, and we advocate backwards and forward testing indicators or systems prior to trading actual funds. We propose conducting your tests on the following five pairs.
EUR/USD
AUD/NZD
EUR/GBP
AUD/CAD
CHF/JPY
If it doesn’t work on these five pairs, chances are it won’t work on other pairs. This is not an absolute, but we’ve found this rule is reliable in most cases.
We’ve added two other pairs to our testing sequence based on feedback we’ve received from our community. They are the:
BTC/USD (Bitcoin/US Dollar)
XAU/USD (Gold/US Dollar)
Timeframes and Results
In our initial test, we’ll run the Kalman Filter indicator on the EUR/USD, the BTC/USD and XAU/USD using the default settings across the daily and 4-hour timeframes on the MT4 strategy tester. We use the fast method of testing the indicator to get a general idea; however, you may also run the tick-by-tick data set for a more precise result (which takes considerably more time).
As No Nonsense Traders – and therefore Swing Traders, we will not examine shorter time frames in these studies. We will also run an additional test, using different values for the settings, to analyze which one may work better and examine the following results:
Total trades
Win/Loss ratio
ROI (return on investment)
There are other metrics included in the strategy tester report, which can be compared, but these three metrics provide the necessary gauge to make quick decisions as to the usefulness of a particular indicator and its settings.
Next, for comparison, we’ll explore the following;
Daily – 1 year
4-hour – 3 months
The reason exceptionally long (or short) testing periods are not included is due to changing market conditions, which might return irrelevant information. A balance of statistically significant data is necessary for accurate results.
And the Outcome…
Below are the spreadsheets listing the results from our tests.
The green highlighted rows represent “basic tweaks” on the settings which returned better results. Are these the best? Not necessarily. Given that variables including testing date range and broker data are different from person to person, you may find better settings.
Remember, the overall NNFX philosophy of taking profit, risk, and drawdown is that YOU are creating a system which YOU will be trading. Don’t let anybody else take that away from you. Part of the learning process is digging in and doing the work yourself. To learn more about these topics, check out the advanced course!
That beings said, the results we post in these blogs should never be considered specific trading advice.
***Note: Remember, never use just this one indicator as your decision of whether to open or close a trade. It should be part of a system.
Money Management
If you are curious as to what money management is used on our tests; we have a certain way of determining wins and losses, which can be found in the Advanced Course. Our goal here is to determine how well the indicator reacts to price with respect to producing a long or short signal. Your system, with its risk profile, will dictate individual returns.
Resources
As we did with past indicator studies, we’ve made the Kalman Filter Indicator available for download on our site from the indicator library. We will keep adding better indicators with each study for your use, at no charge. When you’re ready to get it, click HERE.
