Project-002 "Radiance". Signal level indicator with peak detector (1 channel). Assembly kit
Remember expensive hi-fi devices in their heyday? Have you seen peak indicators on professional equipment? This indicator stuck in my memory from my school years.
Let me introduce Project-002. Signal strength indicator with peak detector!
So, 12 LEDs, 5 of them display overload peaks with a damping delay.
Everything is configured. And the afterglow time of the peaks and the smoothness of switching of all LEDs and the accuracy of the scale and the brightness of the LEDs, etc.
Two operating modes of the indicator are switched: the usual bar and the mode with delayed peaks, for which everything was started.

Assembly of the designer. A trimmer is installed, then (with polarity observed) capacitors, then (checked with a tester) striped resistors.
I install all the passive elements and slightly extend the legs of the elements with reverse side PP so they don't fall out. Then I solder all the legs at once. I use an inexpensive one soldering station entry level LUKEY-702. The soldering iron has been modified, a separately purchased branded tip has been installed - soldering is a pleasure.
Then I use wire cutters to remove all the excess. Make sure that pieces of metal from under the pliers do not fly into your eye or onto the floor. A piece of thin stem is a great pain in the ass. Be careful, friends!
Lastly, I solder the chip in a DIP22 package. Block R-2 is ready.
Here I want to show Alternative option installing LEDs on the back of the board. At the same time, the most high elements The LEDs themselves are obtained on the plane: it is very convenient to adjust the distance from the PCB to the panel of your device. I didn’t cut off the “extra” long legs on purpose so that the LEDs could be removed without loss after finishing the filming of the videos.
Another convenient option- installation of LEDs at an angle of 90° (the legs must be pre-formed). In general, there are a lot of design options for the executive “shining” part - it’s up to your taste, preferences and capabilities.
We solder the wires and cascade the two blocks. It is very convenient to use the cable. By cascading, we achieve synchronous operation of the delay systems for displaying the peaks of all combined blocks. Otherwise, due to the imperfection of the elements of timing chains, we would observe confusion and vacillation in this matter.

Many people remember well how at the dawn of the 80s, tape decks (Japanese) had recording level indicators with peak displays. Having such an indicator at your disposal was the dream of many radio amateurs and music lovers, but assembling it yourself at that time was simply not realistic.
With the advent of microcontrollers, circuitry has changed dramatically, and now the peak indicator circuit does not look more complicated than the circuit simple transistor receiver 80s
We present to your attention a peak signal level indicator on the PIC16F88 microcontroller, mono, LEDs or LEDs are used as indicators LED matrices. The inputs of the left and right channels are combined in it. Or for the second channel it is necessary to make another similar indicator. The number of LEDs in the indicator (matrix) is 40 pcs. An indicator would look good, for example, on such matrices (10 LEDs each).
Or, for example, there are also such matrices of 20 LEDs. You need 2 of them per channel.
Watch a demo video of how the peak indicator works. Here it works in indication mode with peaks in a falling mode, the scale is logarithmic (resistors R11-R14 are missing, or the jumpers have been removed).
The indicator can operate in linear mode, with or without peak indication, or in running dot mode with or without peak indication. The peak indication itself operates in two modes - normal and falling. Normal - these peaks burn for 0.5 seconds and go out, falling - these peaks burn for 0.5 seconds and fall down (if the signal level is at this moment became below the level that was 0.5 sec. back).
The indicator diagram is shown below. The LEDs are used at a current of 3 mA, if you install more powerful LEDs at a current of 20 mA, then resistors R1-R8 must be replaced with resistors of 22-33 Ohms. R11-R14 are installed depending on required regime indicator operation. To quickly switch modes, you can install switched jumpers (“jumpers”) at the points of their connection with the common wire.

The modes in which the indicator can operate are shown in the table below. They can be combined by installing or removing jumpers (resistors). Resistor R1 changes the sensitivity of the indicator, changes the voltage at pin 2 of the microcontroller, and the lower the voltage at the pin, the higher the sensitivity. The optimal voltage at the output is 200-250 mV.

You can, of course, use a microcircuit instead of transistors as the main component, but in my opinion, a device made on a chip has a smaller range of creative thought, that is, you cannot make such fine adjustments, which can be installed in a transistor version. The transistor topology makes it possible to flexibly configure various parameters with the required indication range, soft signal response to LEDs and the same fade out. An indicator chain can be assembled with almost any number of LEDs, as long as there is a desire and need for it. p>
Although in fairness it should be noted that transistor circuits With big amount installed LEDs require a lot of time to debug and adjust them. But on the other hand, it is pleasant to work with such a design; it is very difficult to disable it. But even in the event of an emergency with any of the cells, everything can be repaired without any problems. Clip-on power output indicator does not require large financial costs For its production, the most popular silicon transistors of the KT315 type are used. Any radio amateur is well acquainted with such semiconductors; many began their journey in electronics precisely by using such transistors.
The amplifier output power indicator circuit shown here has a logarithmic scale, taking into account that the output power will be more than 110 W. If we could make a scale to simplify things linear type, then, for example, at 4-6 W the LEDs would not be able to open, or a line of about 120 cells would have to be made. Therefore, an indication device designed for powerful amplifiers must be assembled in such a way that there is a logarithmic relationship between the output power of the amplifier and the number of installed LEDs.
Schematic diagram of a peak indicator
Peak output power indicator and its presented circuit is absolutely simple, and is made with identical cells displaying a visual indication, each of which shows its own level of the amplifier's output voltage. Here is a diagram for 5 indication points:
Circuit of the peak indicator of the output power of the amplifier using KT315 transistors
Using the principle of the diagram shown above, you can easily make an indication for ten points.
Hello, dear readers and visitors of our site, in this review we'll look into it peak and trough indicator called Holy Signal. In general, this indicator has been known for quite a long time, and I would like to immediately point out a very important nuance.
The fact is that this indicator terribly redraws its values. However, this peak and trough indicator should not be used as a signal indicator, because it will be of little use. On my subjective view, this the tool can help build levels support and resistance.
In this article we consider This indicator is with you to clearly understand how to use it in practice, and what you should pay attention to. The Holy signal indicator first became known after the emergence of a strategy for binary options Drake delay stochastic.
The indicator draws on any intervals and pairs
To be honest, this indicator is not often used in practice by traders, and if it is used, it is only as a additional tool. Usually, any indicator of peaks and troughs redraws its values. Let's judge logically, if this kind of indicator clearly indicated reversals, then it would become a real grail, and, as we know, the grail does not exist in the market, and this should be understood. And perhaps they will become a signaling tool for you.
Look in the figure above, this is our indicator. At first glance, this is a real grail, because where the indicator point appears, from there point to point the reversal of the current trend began.
A novice trader may think that this is the grail, but in fact, everything is completely wrong. The indicator redraws their values, in in this case, a dot may appear that signals that a reversal is forming, but the price may move on as if nothing had happened, and the dot that appeared will immediately disappear. Read the page, perhaps after finishing reading both pages you will want to combine something.
And in this spirit the indicator can draw endlessly. Therefore, trading after the indicator point appears is pointless, because it will bring extremely strong losses. Therefore, if you decide to use this indicator and see that its dot has appeared, then you do not need to immediately open a position.
You can use this indicator at any intervals and on any currency pairs, there are no restrictions here.
About nonsense in connection with this tool and in connection with various trading gurus
You know, I have sometimes seen in some sources that the authors advise using this indicator as follows: a dot appears - we open a deal. I repeat, under no circumstances should this be done. Moreover, I have sometimes seen how particularly cunning sellers sell this indicator by simply changing the name. And you know, there are probably novice traders who fall for this. Yes, perhaps a person will not spend a lot of money on buying this shit, but how annoying it will be from the fact that he was simply blatantly deceived.
Now I'm going a little off topic, but I have to tell you about it. If you are a novice trader, then you have to keep your eyes open, because now there is great amount scammers who sell you frankly shitty material that will not be useful, and even vice versa. Of course, you might lose some money on this, but you don't want to be scammed.

Before you spend money on this or that material, you must make sure of everything. You pay your money and you have the right to demand confirmation that material, which is provided to you is really useful.
Many trading gurus will constantly appear. The problem is that the real stars of this market appear very rarely.
I want to give you an absolutely real example directly from my practice. Once I was flipping through the pages on VK and saw that one person was offering everyone who wanted to undergo trading training, where he acted as a direct teacher. He promised that after 1-2 months of training with him, you will forever forget about what losses are. He will teach you how to feel the market and always stay in the black. Naturally, this sounds very funny, but out of curiosity I decided to find out from him what was what.
The training itself was not particularly expensive, about $250. I said, they say, okay, cool, but provide me with the results of your trading, I must see that I am being taught by a competent person.
Watch an overview video of the indicator
He sent me a bunch of screenshots where there were just perfect deals. That is, the person directly caught the market reversals point by point, and promised that he would teach it. Yes, everything looked beautiful on the screenshots, but I told him that screenshots weren’t interesting. Understand that you can draw anything. Therefore, I asked him to provide me with an investment password for the account or at least monitoring of my trading with MyFXBook. In response to this, this character simply blocked me.
What conclusion can be drawn? In this case, the person does not earn a penny on the market, and his task is to sell frankly shitty material in order to profit from gullible newcomers. Remember, always make sure that you are getting really high-quality material for the money you spend.
We use it only as an auxiliary tool
Now let's talk about how to use this peaks and troughs indicator correctly. With his help you can designate zones for yourself support and resistance. Look at example below!
We see that we had a cluster of Holy Signal indicator points at approximately the same level, and through them we will draw a certain resistance zone and wait to see if it will work. When the price approached this zone again, it was broken, but we see that after some time this zone acted as support. - This additional opportunity to come in.
It is worth paying attention to this indicator after the fact, when a reversal has occurred and a market peak or trough has formed. From this indicator point we can draw a level and wait for the price reaction when approaching this level again. We do not react to the appearance of a point, because it may appear, signaling us about the formation of a peak or trough, and the price will continue to move in the primary direction. This indicator peaks and troughs is purely an auxiliary tool!
Each trader in his trading tries to catch the beginning of a price movement, open a transaction that coincides with its direction, and close it upon its completion. In this case, the beginning and end of the price movement most often represent reversals of the current trend on the traded timeframe (in some cases, the movement begins with a flat or ends with it). And such reversals, in fact, are extremes, for the identification of which various indicators of peaks and valleys without redrawing or without delay, which will be discussed below.
Redraw and lag
The indicators are based on certain computational and logical structures based on different principles mathematical analysis. All of them can be classified into 2 mutually exclusive types:
- redrawing (not lagging) - the signal they generate can last certain period(lasts several candles) appear and disappear and, in the end, can either remain or disappear;
- delayed (not redrawing) – the signal they generate appears only after a certain period of time (lasting several candles) after the formation of the identified event.
As can be seen, there is a similarity between these technical tools in that there is a specific time period after the likely occurrence of an identifiable event. During this period the generated signal is:
- or has low reliability (redrawing, non-lagging indicators);
- or does not appear (lagging non-redrawing indicators).
As a result of using lagging indicators, a trader may receive a signal too late - when most of the event being determined (for example, price movement) has already completed. It is advisable to use them to construct graphic figures - channels, support, resistance, etc.
But redrawing indicators allow a trader, when starting to generate a signal, to pay increased attention to the market at the current moment, without 100% trusting such a signal. In this case, you should use additional analytical tools whose confirmatory signals allow you to open positions.
Indicators of peaks and valleys without redrawing
One of the methods for determining extreme points is to analyze the behavior of standard technical instruments built into the MetaTrader trading platform. For example, the EMMA indicator (download ) operates on the basis of calculating the moving average curve (Fig. 1). Then it is analyzed graphically, during which bends (changes in the direction of vertical movement) are identified. A sign of a formed bend is considered to be the moving average moving in the opposite direction at a distance not less than the value of the EMMA_Deviation_in_Percent variable (expressed as a percentage relative to the path traveled from the previous extremum).
The trader can change other parameters of the EMMA indicator:
- EMMA_Mode – prices at which extreme points are searched (0 – Close; 1 – High/Low);
- MA_Period – moving average calculation period;
- MA_Method – moving average calculation method (0 – simple; 1 – exponential; 2 – smoothed; 3 – linearly weighted);
- MA_Applied_Price – prices at which the MA is calculated (0 – closing; 1 – opening; 2 – maximum; 3 – minimum; 4 – average; 5 – typical; 6 – weighted closing).
Since the peak EMMA level indicator is calculated based on a moving average, it belongs to the lagging category.
One of the advantages of EMMA is the ability to easily implement finding extrema at higher periods. To do this, it is enough to increase the MA calculation period in proportion to the ratio of the higher timeframe to the working one.
Another indicator of peaks and troughs without redrawing is Moving MinMax (download ). It uses a unique algorithm, similar to that used in nuclear physics to calculate the tunnel effect. This technical tool displayed in the basement window (Fig. 2) in the form of a histogram, separate areas which, corresponding to the sections of the price chart, are colored in different colors:
- blue – uptrend;
- pink – downward trend;
- yellow – extreme.
Redrawing peak level indicators
Next we suggest downloading Holy_Signal top and bottom indicator. Its algorithm defines extremes as the maximum High or minimum Low over an interval of SignalGap length of candles to the left and to the right. Moreover, if the High (Low) of the current candle is the maximum (minimum) in the interval of the length of the SignalGap of candles to the left, then an arrow will be formed above (below) it, indicating the local extremum. But if during the next SignalGap candles another higher maximum(smaller minimum), then the arrow will be moved to it. Therefore, Holy_Signal is a redrawing indicator.
It is advisable to use it to build support and resistance levels that will pass through several successive minimums or maximums (Fig. 3).
The SignalGap numeric parameter specifies the interval within which the extremum will be searched. Thus, SignalGap determines the sensitivity of the Holy_Signal peak level indicator (the higher its value, the fewer extremes will be identified).
Peak and trough indicator for minute chart
As you know, on short time frames there is a lot of noise that makes analysis difficult. Therefore, when identifying extremes with a short period of analysis, a lot of false peaks and valleys arise, many of which should not be taken into account. In such cases, the PBF_ScalperShowMe_e3Nymous indicator will be useful (download ), the algorithmic part of which is based on mathematical model fractal theory, which allows high degree reliability to identify local and global extremes.
After applying this technical analysis tool to the price chart, it will display signals in the form of arrows and circles (Fig. 4). The former serve as an indicator of local extremes, and the latter – global ones. As a result, visual analysis of price dynamics is significantly simplified and accelerated. Additional convenience is provided by the ability to install horizontal lines passing through the last two found extrema.
The peak level indicator PBF_ScalperShowMe_e3Nymous belongs to the lagging category, which should be taken into account when using it in trading.
