Instructions for Installing EA or Indicator – If Downloaded from AlgoSamurai.com
If you have downloaded a product (EA or Indicator) from algosamurai.com, then here are the 5 steps to take to make sure that the product gets installed properly in your terminal (MT4 or MT5).
Copy EA or Indicator that you downloaded
1. Right-click on the EA and Select ‘Copy’ from the menu. Or Ctr+C.
Note: Make sure that the EA or indicator is in its original file name. For example, the file name should be Ultimate_Trailing_Stop_EA.ex4, not Ultimate_Trailing_Stop_EA(1).ex4. If you are downloaded multiples of the same file, sometimes you can get this different naming scheme, in which case you need to rename back to the original name.
