it is a mq4 and I loaded it to the custom indicator folder. In addition, even the loaded indicators from the FSB forum are not showing. What I am missing?

You can't use indicators written in mq4. FSB needs indicators written in c# in a specific format. mq4 indicators have to be re-coded in order to use them in the program.

No, i Show all Videos from Tutorial. It is not easy with my bad Englisch. But with Show and Pause and click in Program to learn, it works slowly )

Normally the new users download all indicators and switch on all options of the program but it is a good idea to start learning the program slowly step by step.

Then not possible. Right?

We use indicators with .cs extension.

Can i load Indicators with .ex4 filename?

Is there a way to compile indicator without to rerun the software i.e. by pressing a combination of keys?

Thanks in advance

Put your custom indicator file in the Indicators folder.
