The Expert Advisor is rewritten from MQL4, the author ExpertTrader, link to the original –
How it works
GO is calculated using the following formula:
GO=((C-O)+(H-O)+(L-O)+(C-L)+(C-H))*V;
Where C, O, H, L – Moving Average value on Close, Open, High, Low prices. V – signal bar volume.
If the value of GO is greater than 0, a buy order is opened, if less – the buy order is closed and a sell order is opened.

Parameters
Lots – lot; when 0, the MaxrR parameter is used.
MaximumRisk – Risk (default value Lots=0).
Shift – Bar on which indicators are checked: 0 – forming bar, 1 – first formed bar.
MAPeriod – MA period.
MAShift – MA shift.
MAMethod – MA method.
VolVolume – Volume.
OpenLevel – If the value of GO exceeds the level, a buy order is opened; if it is less than -OpenLevel, a sell order is opened.
CloseLevelDif – Difference between opening and closing level value should be set in positive value. Closing level must be equal or less than the opening level).
If OpenLevel has 0 value, bar volume value do not influence so OpenLevel and CloseLevelDif parameters are included. These parameters are absent in the source. External parameters have been included for Moving Average.
