Hi everyone,
I want to apply a custom template, so that my EA immediately starts to change/show the chart with that template. It is called "normal.tpl"
Before, I want to check if that file is existing. So I print my terminal data path
which prints
G:\Meine Ablage\Trading\MetaTrader 4 IC Markets
and ask if there is the file I want to apply. I read in the documentation
It always prints NOT FOUND.
Same with
or
or
Yet, to try everything, I manually under windows copied the file "normal.tpl"
- in G:\Meine Ablage\Trading\MetaTrader 4 IC Markets\normal.tpl
- in G:\Meine Ablage\Trading\MetaTrader 4 IC Markets\templates\normal.tpl
- in G:\Meine Ablage\Trading\MetaTrader 4 IC Markets\MQL4\normal.tpl
- in G:\Meine Ablage\Trading\MetaTrader 4 IC Markets\MQL4\templates\normal.tpl
I am sure it is a very simple problem, yet I struggle to find the correct file path
