EA is not reading mq4 file, I never said that.so what you saying is the ea reading the mq4 file? even if you make changes to the indicator settings on the chart it wont read the settings as per indy attach to the chart?
i dont really understand
Some indy's come in mq4 form, and you can change setting's before you compile it.
For most ea's you don't need to slap indy on the chart, as long as indy is present in the folder. Some ea's will let you change setting's on indy in the ea settings.
So if you don't have the option to change setting's of the indy in ea, and don't need to place indy on the chart for the ea to work, means ea will use current setting's of the indy in the folder whatever they are.
