Big Bang MT4

Big Bang is a 100% adaptive expert advisor based on price movement and Support and Resistance levels. It is a combination of simple settings and powerful trading techniques.

Version for MetaTrader5 is here: https://www.mql5.com/en/market/product/48021

Note #1. Max bars in chart setting in your MetaTrader MUST be set to 250 000 => Check screenshots section.

Big Bang needs at least 1 year of M1 data. Please, make sure that you have that loaded in your History Center.

Note #2. If testing in MT4, during the first year Big Bang will only collect data and open NO TRADES. So, start your tests 1 year before the desired date.

If you have any questions or doubts about your setup or configuration => CONTACT ME.

Recommended pairs

Default settings are good for EURUSD, GBPUSD, EURJPY, USDCAD, AUDUSD and USDJPY.

If you want to use other pairs, the settings should be optimised in order to find the best .set configuration.

Broker and Leverage

Big Bang is not broker sensitive, you may chose any broker you trust to.

If you use a recovery algorithm, you will need to have enough margin for additional orders with bigger lot sizes. Recommended leverage is 1:100 and 1:500 is even better.

Recommended TF

Time Frame of the chart for real live execution does not matter. But, make sure that you have all timeframes data available in history center (F2).

For BACKTESTING IN MT4 the timeframe must be M1. You also should load all available timeframes in MT4. In MT5 any timeframe for backtesting will work.

Settings Description

Lot Size - can be fixed or set dynamic as lots per every 1000 of Account Balance. If set dynamic, the lot size will be calculated as follows = (LotsPer1000*AccountBalance/1000)

Max Additional orders - Smart Recovery :enables basket trading to recover from drawdowns quicker.

Trend Detection period - defines trend detection sensitivity. The bigger the value, the slower is trend change detection.

Max Pairs at a Time - limits number of pairs which are traded at the same time. Pairs are counted by the same Magic Number.

One Side Only - if true, there will be only one side open at any given time (either buy or sell). No situation when both sides open at the same moment. For FIFO compliance

Spread Filter - allows avoiding trades in high volatility times when broker increases the spread.

Hidden Stops - if this mode is enabled, no SL and TP are sent to the trade server. All trades are closed from the EA. Broker does not see your stops.

Magic Number - unique EA identifier. Should be set different in case when multiple instances of EA are used on the same currency pair.

Buttons Description

No Action - enables / disables "No Action" or Sleep mode, when EA is not taking any trading action. May be useful when you decide to manage trades manually. 

Kill Buy/Sell - Closes open orders.

Soft Exit - if enabled, only current cycles will be finished. No new trading cycles will be allowed to start.

Recommended Setup #1

Balance : $1000 

Settings : Default



Recommended Setup #2

Balance : $2000 

Settings : Default, with Fixed Lot = 0.01 and Max Pairs parameter set to 2 or 3


Recommended Setup #3

Balance : $5000 

Settings : Default, with Fixed Lot = 0.01 and Max Additional Orders = 7



Big Bang can work on VPS solution from MQL5. But Big Bang has some nice graphical controls, which can only work on "normal" VPS with desktop access.  


1) Big Bang is designed for HEDGING accounts only (when multiple orders are allowed on the same pair) and it was not tested on Netting accounts (where all orders merge into a single position).

2) Big Bang is designed for trading ForEx. It was not tested on metals, shares etc.

3) Big Bang will not work on accounts with overnight positions rollovers (closing and reopening by broker).

Had this EA running for 2 weeks now and it is one of the most comforting EAs I have purchased to date. All trades have given me profits so far and it seems to know what it is doing all the time. Great EA, and Great Customer Support. Thanks Andrey.

Thank you Mr Andrey for you hard work and excellent customer support

The tests with Strong Signals Only looks very promising. The SSO eliminate the trading fear in quite good way.

Also Smart Recovery option helps to secure profits.

Trading greed - we can adjust in 'risk per 1000usd'.

Happy trades , everybody!
