The Expert Advisor provides a possibility to display the indicator used in it on the current chart directly from the Expert Advisor. There is no need to install the indicator in the chart manually. This is quite convenient, as the indicator is displayed on the chart automatically after the Expert Advisor is installed on the chart. This indicator always has input parameters identical to the Expert Advisor's ones. Indicator is present in the chart only if it coincides with the chart's time frame! 

Default Expert Advisor's input parameters have been used during the tests shown below. Stop Loss and Take Profit have not been used during the tests.
