MT4 Expert Advisor “VBO33”

VBO33 is a fully automated trading system, developed by strategy developer and programmer Kay Stoeffler, CTO at Zefstech Ltd.


VBO33 was programmed in MQL4 as a so-called "Expert Advisor" (EA) for the well-established and widely used trading platform Metatrader 4 and is a product of several years of research, development and optimization.


In the development of VBO33, as of all other trading systems built by or for Zefstech, focus was put on achieving long-term profitability over a wide range of tradable assets (mostly currency pairs) under the occurrence of relatively acceptable drawdowns.
The results of extensive back tests indicate a consistently profitable performance for the period of at least the last 10 years.


The VBO33 EA can trade multiple currency pairs in multiple time frames alongside other EAs provided by Zefstech on one and the same Metatrader 4 account, being a part of a portfolio of diversified trading strategies that distribute risk across a variety of different assets and strategies and help to compensate losses and minimize drawdowns.



The VBO33 strategy


VBO33 uses a special formula, based on Kay Stoeffler’s proprietary technical indicator "VPower" to identify genuine market breakouts, driven by high volume / momentum, which usually occur during the first few hours of the European and the US market sessions and which are often caused by important news releases and major economic events.
Optionally, a combination of several other technical indicators can be used to confirm and filter the signals.




Traded pairs and trading time ranges


On the basis of the most recent back test results, VBO33 is currently set to trade the following currency pairs during the following time ranges (EET):


EURUSD (9:05 – 12:59 & 14:00 – 18:59)
EURJPY (9:05 – 12:59)
EURAUD (9:05 – 12:59)
GBPUSD (10:05 – 12:59 & 15:35 – 18:59)
GBPJPY (10:05 – 12:59)
GBPAUD (10:05 – 12:59)

USDJPY (9:05 – 12:59 & 15:35 – 18:59)
XAUUSD (15:35-18:59)



Best & worst market conditions


The VBO33 strategy should be performing best in a volatile market with strong and sustained price moves.
Poor performance is to be expected in a choppy, undecided and nervous market with a lot of false breakouts ("fakeouts").
