Probabilities Distribution PRO Indicator  Trading Systems  7 September 2019
Introduction.
Most
of the indicators currently used by traders in the Forex market were created for another market – the stock market and for another time, when
there were quite monotonous trends and quotes were not so volatile as at present, when there are no trends as steady trends of unidirectional
price movement. Therefore, the entire existing arsenal of
indicators is not very suitable for trading in the Forex market and does not reflect the key moments of the state of this market.
To assess the condition of the Forex market and its instruments, it is necessary first of all to analyze statistical
histories of their quotations, which allows identifying patterns that are important for trade, which are latent for the standard
indicators (supplied with the MT4 trading platform). One of these, providing a deep statistical analysis of instruments is the indicator
PDA (probability distribution of price and
asymmetry), which, based on the analysis of the
smaller time frames, calculates in real time the probability distribution of the price for the larger
time frames, and also calculates the asymmetry of this distribution. The
visual control of probability distributions and asymmetry, which provides the indicator PDA,
allows us to achieve a deeper understanding of the modern market, namely:

statistically strictly identify the current price levels and assess the probabilities of the current
(for the current moment) price in other segments of its fluctuations; 
to reveal the microstructure of the true trend movement, as a sequence of such transitions
from one price level to another, that have a certain shift in the balance of probabilities towards the growth of the price or its fall;  establish the beginning of a new trend movement based on the critical output of an nonlagging
average beyond the current price level and exceeding the certain level of asymmetry.
1. Principles of the indicator.
1.1.
Calculation of the probability distribution
.
To
calculate the probability distributions on time frames М5Н4,
the data of the minute chart – М1, is
used. For the daily is
used time frame M5; for the weekly time frame and
for the monthly time frame – M30. The
use of smaller time frames for estimating the probability distribution in these large time frames is not advisable, and it is impossible not
only because of the braking of the program loaded with large arrays, but also because there is not enough
big of M1 history in (for calculating probability densities) the scales of such graphs. Therefore, before the indicator
PDA is installed on the chart of a tool, you first need to load the history ( Tools /
History Center) quotes for this tool, and also to increase to the limit the options “Max bars in history ” and
”
Max bars in the chart” (Tools /Options / Charts) .Note
that if on some largescale timeframe of data for calculating the probability distribution is not enough, on the ”
Experts” tab of the window of the term MT4 there will be a message “Download
the quotation history of
… “.Indicator itself is
resourceintensive and requires at least a 4core processor 2.8 GHz and 4.00 GB of RAM .If
the indicator will brake the MT4 terminal, then in the indicator settings it is necessary to reduce the
«Number of countable bars of the current chart (<=200)» , which
is the default 200.
The
calculated probability distribution and asymmetry
has a sliding character, and the interval used for calculating the data is determined by the input parameter «
The averaging period in the bars of the current graph» ,which
we denote IS ;if,
for example, IS = 15, and time frame H4, then the
columns of probability values corresponding to the time moments at H4 are calculated by 15 * 4 * 60 = 3600 points of the graph M1, i.e. the
last column (zero bar n = 0 to H4) – over the last 3600 points of the time frame M1, the penultimate in the range of values [241, 3840], .., nth in
the interval [240 * n + 1, 3600 + 240 * n ] minute chart. And,
if, say, IS = 1, then the last column is
calculated according to the last 240 values of the minute chart, the penultimate column is calculated according to the values of the
interval [241,480], etc., with the mapping, of course, in all cases, to H4.
The program splits the total price
fluctuation for a given averaging period into
seven equal intervals and calculates the frequency of the price hits of historical data of already small timeframes in that
intervals. From these 7 intervals for each moment of the analyzed large time frame, rectangles of the probability mapping
are formed
(7 rectangles for each, marked by a bar of a large time frame, time point). Calculated
on the basis of the statistical frequencies of the price (small timeframes) hit in the intervals specified by the program, the probability
columns can be displayed in the main terminal window in two ways:

in the form of a color code, the type of the spectrum of visible light, when the most probable
values are closer to the violet area, and the least probable values are close to the red, with the coloring of the intervals by the
corresponding colors (the order of encoding the decreasing probability by means of the color scale is specified in the settings and can
there be changed at the request of the user);  The averaging period in the bars of the current graph (2n+1) – averaging period (199).
 Number of countable bars of the current chart (<=200) –
number of calculated indicator graph bars (1200).  Shifting the calculation area of the indicator – global
indicator shift (0100).  The nonlagging distribution is calculated – calculate a
nonlagging distribution.  The nonlate channel is calculated – calculate the current nonlagging
channel.  Show

intervals, with the corresponding colors.
1.2.
Calculation of nonlagging moving average
.
The PDA indicator calculates the
nonlagging moving average, which is calculated at the points (Inf, n + 1) in the usual way, and at the points of the [n, 0] segment, where 0 is
the last bar number, is algorithmically and there is a curvilinear sector (cover out the confidence interval) in which the line of the
nonlagging moving average fits with the confidence level specified in the indicator settings.It
is clear that the more the confidence probability value is taken (which by default is equal to 0.5), the wider the curvilinear sector of the
confidence interval is obtained. If we take the confidence probability equal to zero, then the sector of the indicator readings at points
[n, 0] will shrink to a curve, which will pass through the most probable values of the nonlagging average. Statistical studies show that
the price around the nonremaining average is distributed according to the Laplace law. Knowledge of the distribution law and the
algorithm for calculating the most likely nonlagging average on the [n, 0] segment allow us to calculate the confidence interval sector.
1.3.
Calculation of nonlagging asymmetry
.
The PDA indicator allows
you to predict the beginning of a change in the direction of trends, long before their visual manifestation on the price chart, by
calculating the asymmetry that is displayed in the lower window of the indicator.
The author statistically revealed
that before changing the direction of the trend, the probability distribution function of the price is made as asymmetric as possible. More
precisely, the price movement in any direction always pulls sideways the function of its distribution, but when the thirddegree root of
asymmetry divided by the standard deviation exceeds the unit in absolute value, the price will change its direction. This function the
indicator operation is based on this regularity. The indicator calculates the value of the third degree root asymmetry normalized to the
standard deviation, i.e. magnitude
ASUMM= (< (x – <x>)^3 >)^(1/3)/ (< (x – <x>)^2 >)^(1/2) ,
where <…> – is the averaging sign, which, when it is module exceeded
the unit , serves as a powerful signal to change the direction of a previously established trend.
It has also been established that the
asymmetry plot changes sign when the price probability density function makes a sharp jump, which is characteristic of price dynamics.
The sliding asymmetry counted in a
particular window, as well as the variance and the moving average, lags behind by about the floor of the averaging period used. Therefore:
(1) For past price values, the asymmetry plot shifts back through history by the amount of delay; (2) To receive a
signal in a timely manner, a special compression algorithm for the asymmetry calculation period is applied when approaching the beginning
of the current history.
At the same time, to ensure the possibility of calculating such asymmetry (creating a sufficient array of
calculated points) on the M5H4 time frames, be used the data of the minute chart is M1, the daily time frame is – M5, the weekly
– M30, and the monthly – H1. On M1, this indicator, respectively, is not used.
2. Modes of operation of the indicator PDA.
For the convenience of reading the
colorcoded probability values from the indicator prob_distrib, it is desirable to make a black background on the color scheme of the main
window of the MT4 terminal and display prices also with a dark line or red and green bars.
The
moving average, taken with the averaging period
2*n+1, is known to lag behind the n bars;
the sliding probability distribution that calculates the
first mode of the PDA indicator also lags behind,
which in this case represents the data in such
form (Fig. 1).
Fig. 1 .Mode for
calculating the sliding probability distribution of prices and asymmetry
IS =15.
However,
since the information on the frequencies of the price hit in given intervals is obtained on the basis of a large amount of data extracted from
the lower time frames, it is possible to obtain algorithmically the
without delay probability distribution, the calculation of which constitutes the second mode
of operation of the indicator .In this case, the previous type of
distribution is shifted to bars n to
the past, and information about the distribution on the n1 bar is found on
the bars 2*(n1)+1 of a large time frame, i.e. on the points (2*(n1)+1)*TL/TS,
where TL – the duration of a
large time frame, TS – – the duration of a small time frame, that detailing a
large, the nk bar on the 2*(nk)+1 bars
of a large time frame, i.e. on (2*(nk)+1)*TL/TS points, and about a zero bar on on it
himself, more precisely, on an array of the prices equal quantity TL/TS ;at
the same time, the probability distribution is calculated not on a bar that may be incomplete, but on the last such number of points of a small
time frame that forms a full bar, which allows obtaining distributions for individual bars (Figure 2.1).
Fig. 2. The mode of calculating the without delay probability
distribution
IS =15.
Fig. 2.1. Probability distribution over bars
IS =1.
In the third mode , the
algorithm for calculating the nonlagging probability distribution is still more complicated. The current
price channels corresponding to the averaging period are calculated at the end of the history. (Fig.
3).
Fig. 3. Calculation mode of nonlagging distribution and nonlagging price channels
IS =15.
In all operating modes, the
confidence interval of the nonlagging average can be, as well as painted over.
Shading allows you to better see this interval itself, but impairs the vision of the details of the probability
density distribution. Therefore, by default, the confidence interval is not painted over, but is marked only with blue (top of the
interval) and red (bottom of the interval) crosses.

Shading the confidence interval of the nonlagging average. IS =15.
Fig. 3.2. The third mode with filling the confidence interval of the nonlagging average closeup.
In
each of the above modes (13), the probability density mapping can be changed from its color coding (colors can be customized by the user) to
the numerical presentation
(Fig.4).
Fig. 4. The third mode with numerical probability mapping
IS =15.
In
the third mode, based on the calculated channel limits (which then need to place stops), the deposit and the specified risk level, you can
also calculate the lot size for the trade within this channel, the lot information is displayed in the main window where its location is
configured and can be selected, both at the bottom of the channel and at the top (Fig. 5).
Fig. 5. The third mode with the calculation of the lot.
The
indicator is resourceintensive and calculates a small number of bars, but to search for possible new channels, the calculation area can be
moved deep into history, for which the «Shifting the calculation area of the indicator»
parameter is set in the settings.
The
current mode of operation and all its characteristics are printed on the ”
Experts” tab of the window of the terminal MT4.

indicator settings are shown in Fig. 7, where they are described in the terminal window “

4. Identified by the PDA
indicator of the laws of the market and how to use them for successful trading.
Looking
at the color maps of the probability distribution, it is easy to notice that the places where the price “trampled on” the most, form on all time
frames rather extensive horizontal bands (Figure 89), which are similar to discrete energy levels, when the price from one level to
another passes jump, almost avoiding intermediate points, in which the probability density of its hit are sometimes minimal
.And, if the averages move smoothly, falling into such zones of maximum probability by
passing through all intermediate points (and otherwise can not be) and do not distinguish similar probability concentration bands, these
zones are easily identifiable by the indicator PDA, since they
really form are constant levels that are essentially discrete or torn apart from each other.
Fig. 8. The bands of the maximum probability concentration on H4.
The
existence of such zones can be explained from a psychological standpoint, as a consequence of the habit of key market participants, which
determines
pricing, when they are confident in the adequacy of certain price values determined at a given moment. This key market
participants try set this price for some time, which continues until important events occur. Such levels, imprinted in the memory of these
participants, acquire a strong tendency to repeat, which can also be seen on the color distribution of the probability and should be used in
the game .Namely, if a trend has been signify, say, to an increase in the price,
then necessary (by examining the probability distribution on history, for which it may be necessary to shift the indicator calculation
area in the past by the «Shifting the calculation
area of the indicator
»option )to
identify
maximum probability zone above current price, where to place the takeprofit, since it is
possible that the direction of price motion will change after this zone, but price will reach its with a high probability. From the
analytical point of view, the existence of such price zones and their isolation from each other is also understandable, since highly
nonlinear equations, in principle, describe such complex systems as the market, have huge sets of sharply differing solutions that jump
and unpredictably replace each other in points of bifurcation, after which the price only fluctuates around such solutions until the next
bifurcation.
The
very tendency to change the level of maximum probability is expressed (Fig. 9) in the intersection of the moving average and the band with a
fairly low probability (from gold to redorange), which should be identified by
probability distribution without delay and moving average without delay to avoid signal lag.
Moreover,
the unbiased normalized asymmetry calculated by the
PDA indicator, when the module exceeds one with ASUMM > 1 serves as a leading signal to a possible rapid change in direction of a previously
established trend.

D1.
5. Successful trading strategies using only PDA
indicator.
Preliminary actions.
First,
on the timeframe chosen by you for trading (M30D1), roughly estimate the average length of the white bands
<l> = (l1+l2+…+lN)/N, where N
–
the number of bands visible on the chart, li –
their extent.
The
indicator for both strategies is used in the
third mode , where are calculated channels, probability
distributions and mean without lag.The indicator channel and, accordingly, is intended
mainly for trading through channels.
1. Inchannel strategies.
The
indicator PDA allows you to reliably trade in channel
strategies. Such
trade should be carried out on the already welldrawn (but not too long compared to their average lengths) white bands <l>/4
< l < <l>/2
and, of course, beforehand (at least 2 hours for trading on H1 and H4) before important
news that may shift the price level to the new channel. Moreover, the asymmetry
modulus should not exceed unity and even approach it. In this case, the opening of positions should be done when the current price is either in
the yellow or green sectors, and take the takeprofit in the middle of the white line. The stops are placed slightly further than the full
distribution channel (Figure 10). The
value of the lot is calculated by the indicator itself, if
in the indicator settings “Is channel strategy used?” set
true.
Fig. 10. Channel strategy.
2. Strategies for channel breakdown
.
The
bands of maximum probability jump discontinuously at the intersection of the without lagging mean of the red strip, which is the band with
the minimum probability. In this case, the asymmetry sign is also replaced. Therefore, with the
PDA indicator,
the channel breakdown strategy can also be implemented in the form of a breakdown of the lowest possible level in an absolutely established
channel
l ~ <l>, namely: if the normalized asymmetry exceeded the unit
in magnitude or approached it, a pending order is placed in the middle of the current red band (Buy_stop – if the red band is above the white and
Sell_stop – if the red band is below white). A profitable order is closed manually when the price reaches a new established white band
l ~ <l>/4. Stoploss is also placed a little further than the full
probability distribution channel (Fig. 11). To calculate the lot, the option ”
Is channel strategy used?” must be set to false.
Fig. 11. Channel breakdown strategy.
With
this indicator, you can also use the classic form of the channel breakdown strategy by placing a pair of pending orders (
Buy_stop and Sell_stop) and their stops just below both boundaries of the established channel.
3. Trend strategy
.
Fig. 12. Trend strategy
with opening order on the change of the trend and iteration of modifications
Stop Loss.
4. The strategy of moving along the bands of maximum probability
.
There are no trends, as such, on the
modern highly volatile foreign exchange market, but there is a strongly fluctuating movement along the bands of maximum probability and
the change of these bands. An upward trend is identified when transitions to the upper bands are more likely than transitions
to the lower bands, i.e. Pup >Pdown . The downward trend is the opposite – transitions to the lower bands are more likely than transitions
to the upper ones. The stronger the prevalence of one probability over another, the more pronounced the trend is. If these probabilities are
equal or their proximity, Pup ~ Pdown , we get a flat. Any random jump against a pronounced trend is treated by traders as a pullback.
These bands are pronounced, and their changes are accompanied by certain, statistically recorded changes. Therefore, trade on the change
of these bands is the most reliable.
If the position is not open, then the
excess  ASUMM > 1 gives the trader a sign that a transition from one band of maximum probability to another band will occur soon. Then the
trader should then be ready to open a position. If after that the unbiased average has moved from the white sector to the red or orange sector,
then you need to open a position in the direction of movement of the unbiased average (Fig. 13)
.
The position is closed as soon as the price is again in the white sector or when excess occurs again  ASUMM > 1.
