Expert statistic Trader - this
trading strategies, based on two ideas: the idea of probability
occurrence of an event and the idea of money management. The expert gives the trader a huge
opportunities in terms of settings and determine the level of risk.
The idea of probability:
I get an equal chance to make a profit or loss, if the Take Profit More Stop Loss? Maybe!
transmits the first N transactions (spends virtually the appearance of the signal), and only after receiving N consecutive losses
It reveals the real position. If N = 0, the first deal is real. If for example N = 2, the actual position will be opened
Only after two consecutive losses. If after the first virtual unprofitable
second transaction virtual transaction will be profitable, the expert will start the countdown
again. If the examiner will open the real deal, and it will be unprofitable, he (with
signal appears) open next. And so - 10 times before profit.
After making a profit (on any of the ten series of steps) to stop its expert
I consider the price change of the asset as a random or not analyzable
process (because of the huge number of factors affecting it). For a trader to open a position, there are two
outcome - profit (Take Profit) or
of loss (Stop Loss).
Numerous tests on different currency pairs, different time periods,
different settings have shown that the results are subject to a certain scheme.
The main factors - the size of Take Profit and Stop Loss, and not at all the indicators and filters
etc. If Take Profit is Stop Loss, the probability of occurrence for them
is, if Take Profit Stop Loss longer, the probability of occurrence of Stop Loss is favorable, ie Stop Loss will occur more often and more often
precisely to the extent in which it is less than Take Profit. EXAMPLE: Take Profit = 100, Stop Loss = 50. When making absolutely 1000
random trades about 33% complete profit, about 67% - a loss. Moreover,
The more transactions, the more the proportion of distribution of profit and loss
even after a long series of Stop Loss Take Profit should occur. In order to determine how much
transactions to be missed, it is necessary to conduct regular testing. Statistics
shows the average number of losing trades in a row happens. And correspondingly,
so many of them it is logical to miss. Of course, sometimes expert will
skip and a potentially lucrative deal, but for a long period of time
he will avoid many initially losing trades.
The idea of money management:
deter aggressive money management methods, such as doubling the position
after a loss, due to the fact that a series of losses can become so long that
a trader can not open another position and lose all or most of the
deposit. But definitely give up the opportunity in the next transaction
recover losses and make a profit is not worth. If kept under control
the risks and try to eliminate the too long series of losses, then this tactic
It may be a viable and profitable for small controlled drawdown.
Sometimes - even allow you to display in a profit strategy, which at constant
the size of the deal would be unprofitable.
Statistic Trader allows
set the size of the lots for a series of ten transactions. The trader has the ability to
adjust the aggressiveness of capital management in its sole discretion, with
I am counting on the fact that knowing the statistics and missed the first losing trades, he
Do not get too long series of actual losses.
Tips for setting up an expert:
- Opt for a currency pair and define its
the average daily volatility. For example, I chose a pair of euro-dollar. its average
day volatility of 70 pips.
- Install Take Profit in the amount of average daily
Volatility (pip 70) and Stop Loss in 2-fold
less (35 pips).
- Testing a strategy on the history of at least
three months. Determined by the average number of consecutive losing trades in such
sizes Take Profit and Stop Loss. For example, it is equal to 3. concludes
that before opening the real deal, it is necessary to wait for three consecutive losses.
Install N = 3
in Expert settings (i.e., skip 3 consecutive loss).
- My approach to capital management -
receive a transaction (a series of transactions) from 0.5 to 1% of the deposit. In case one or
several consecutive losing trades, at least - to play the resulting loss. I
I adjust the size of the lots series as follows:
Step 1: Lot 1, Step 2: Lot 1, third
Step: 2 lots, 4th step: Lot 3, Step 5: 4 lots, 6th step: Lots 6, 7 th step: 9 lots,
Step 8: 9 lots, the 9th step: 9 lots, the 10th step: 9 lots.
Not difficult to calculate that, after receiving
profit on one of the first seven steps, I played obtained before the loss and
I get a small profit. At the same time a drawdown even after 5 consecutive losses will
no more than 4% of the deposit, after 7 consecutive losses - about 9% after 10 -
about 15%. It is no longer, and maybe even less than that of some strategies not
using the increase in the volume of the transaction after the loss. If testing
History has shown that the maximum length of a series of losing trades was 10
and it was only 1 time in a year, then we can hope that, skipping 3-4 loss
in a row, the maximum will still 6-7 losing trades in a row, and the probability of this
It will be very low. Basically, profit is the first or second transaction
after missing several virtual loss.
Another more conservative option:
Step 1: Lot 1, 2nd step: Lot 1, Step 3: Lot 2, Step 4: Lot 3, Step 5: 4
item, the 6th step (starting from the beginning): Lot 1, Step 7: Lot 1, Step 8: 2 Lot 9 minutes
Step: 3 lots, 10-Step: 4 lots. In this case, if losing a series of tightened
than 5 steps, it is possible to let them go back to the original size
capital, but do not lose more than 5%.
the selection parameters can independently determine not only the size of TakeProfit and StopLoss and the throughput of transactions, but also to choose a currency pair and timeframe,
the most appropriate at any given time, as well as set the size of the lots in
series. Between pronounced trend movement or before exiting important

Features of work:

It creates a global variable Start, in which the start time is saved

global variable Stop. To start a new session after taking profit need
remove from the chart expert and remove the corresponding global variables Start
and Stop (call list of global variables - key F3, or the tab "Tools - Global Variables" in
