To use non-standard indicators on the MT4 trading platform, select Open Data Folder command in the File menu. Then you need to choose the MQL4 folder and copy indicator files to the Indicators folder.
In case the custom indicator is imported correctly, it will appear in the Indicators menu of the InstaTrader 4 trading platform.
While working with custom indicators, it is necessary to remember that if the code is incorrect, the indicators can cause a slow system response or disappear from the chart. In such cases, you should directly contact the developer of the custom indicator.
For this reason, we recommend installing indicators and expert advisors only from those developers who you can contact directly.
