Hello Cedric,
To avoid setting the inputs each time you run the EA, you can
set them once and save them in a file by clicking
“Save” in the bottom right corner of the window.
Then you can use this file by loading it with the
“Load” button.
Also the EA needs to be attached to only one chart and will
work for all symbols.
About the lot size, please check if in “Trade
Management Settings” section, in “Select Money
Management Method” that “Fixed Lot” is
selected and set the lot size in the field bellow. Let us
know if you have any other questions.
