Boris Vilenski from Israel decided to write an automated trading system based on his professional experience, though it is far from trading. This system underlies his competing Expert Advisor. For the EA BablOKoS_EURUSD, Boris developed his own indicator that produces parameters, based on which decisions are made.

Hello, Boris. We congratulate you on your good results. Could you, please, tell us a little about yourself: what is your profession, and how long have you been involved in trading?
I took an interest in trading about a year ago and nearly in half a year I concluded that the best potential for me can be acquired from the automated trading. I got a degree in physics, and the topic of my doctorate thesis was connected with physics of disordered systems. Besides, my working experience of several last years was connected with processing signals and, to some extent, with financial sphere. All this brought me to the idea of writing an automated trading system.

Do you remember your first automated trading system?
Of course I do! This particular system is participating now in the Championship and I continue working on it.

The name of your Expert Advisor is very funny (Bablokos can be translated from Russian as something like 'bucks-reaper' MetaQuotes Software Corp. note). Have you used it in real trading?
The name of my system reflects what I want to get from it. I use it in real trading, but with a fixed lot size.

It means you find using such a method in real trading justified? Why is it so attractive? What are its advantage, in your opinion?
My method models the market behavior learned by history and allows to make rare correction of parameters without changing the model, i.e. the algorithm underlying the Expert Advisor.

Could you, please, describe the general algorithm of your EA's operation?
The algorithm is non-trivial, so it is hard to describe it. I can only say that fuzzy logic is used in it. It represents more than 2500 code lines in MQL4 language and handles several dozens of parameters. Unfortunately, all my attempts to simplify the algorithm result in a worse P/L correlation.

You have written that your EA is waiting for a favorable moment for closing in order to get the highest profit. Could you specify what moment you are telling about?
I wouldn't like to answer this question in details so far. I can say only that in each specific situation, the calculation is different.

And how does your Expert Advisor open positions? According to what signals?
I use my own indicator built into the EA. It constantly produces signals as a set of parameters. If they correspond to a certain preset conditions, a position is opened.

And you don't use standard indicators, do you?
No. I have tried some, but in my system this didn't bring any satisfactory results.

You EA seems to be based on a counter-trend trading system. It looks like you are using your own oscillator-type indicator. Is it true?
No, it's not. I developed and optimized the system for different market conditions. Obviously, the current market development dictates the counter-trend behavior of the EA. Unfortunately, I cannot refer for sure my indicator to a certain category.

Your Expert Advisor is attached to a minute chart. Does it analyze only this time interval, or does it also take into account the values of larger timeframes?
Yes, such values are also taken into account. The result of my EA's operation does not depend on the chart, to which it is attach
