Would like help understanding the Custom Indicator running twice

I'm sure it's out there, but I have not found a discussion of this: Brief: The Custom Indicator runs twice each bar, once on it's own and again when referenced in the EA.

Need help - Terminal will not launch

I don't know if this is a MQL4 question or a Windows question. This has happened a couple of times now with a demo account . I don't want to lose a live account this way: • I make a mistake in a Custom indicator, infinite loop for example, the terminal freezes and I have to close it through the

How can you run automated trading when data goes missing? Account specific market data?

This is really shaking my confidence in automated trading. I've attached a screen shot and part of my chat attempt to resolve this. These are two demo accounts. I open the same AUDUSD 5min chart in account 756 and it appears normal. I open it in account 326 and data is missing from 5:15 May 6

Basic question about MT4 and forex servers

I want to be sure I understand how MT4 handles the forex servers. I’ve been working with the assumption that there are market data servers which tick the EA and a broker server which I need to query separately for account information . I started cleaning up an EA to stop it from checking

Error 133 Trade Is Disabled

I'm posting this because I could not find a useful reply to others who have asked about this error. I just encountered it for the first time today. I presume there are other reasons for this error, I'm just offering the one that affected me today: My broker explained something I had not known
