I did that several times yesterday before write in the forum. Even I uninstalled FST in order to not interfere with FSB Pro.

Now I´ve installed FST again but it´s closed. I´ve closed all, restarted my computer and reinstalled the expert in MT. I have only one chart opened in MT only with your expert and ID=101, such in FSB and nothing more. Same result.  It is very strange.

EURUSD-Pro is the name that my broker uses to call EURUSD. It works in FST with no problem. It uses this name to differentiates from the other one because Pro is ECN and EURUSD is MM. That´s the only reason.

Some third party software causes such problems also.

It was happen to me before. There was nothing suspicions in FST and MT4. The problem was found in a Garmin map software running in my machine.

I made a special too lfor monitoring MT4 - FSB Pro (FST) connections.

There are times when performance can be affected by 'gremlins' which have installed themselves in our machines. Sometimes a thorough clean out is appropriate using Malware bytes or something similar, different from the normal antivirus.

Also, our modems/routers can become cluttered and need to be unplugged at the wall and allowed to rest for 5 minutes and then restarted in order to reset them and re establish good connectivity.

Windows machines are prone to clutter which throttles performance, the registry has to be cleaned out on a regular basis to keep good performance.

There are many factors which can make performance deteriorate and we have to be aware  of those conditions and constantly maintain our computer systems.

The amount of data in Mt4 can impair its performance.

I am glad you found a solution..... I have had many difficulties as well..... and I found that I had to clean out my machine regularly to make things work properly.

Hopefully smooth sailing from now on for you.

I think I would prefer to have XP for FSB, Windows 7 seems friendly to weird gremlins.
