Tips for installation of Leotrader Pro EA

Old Posts

I was interested in this product since the launch as it was something new in the Forex Eas and had a good profitable performance according to the live trading statements. However, even for me it was difficult to install the EA at first. The new update had solved almost all the problems, but there still exist some issues, so in this article I would like to give people some tips that can help to install Leotrader version 1.10 properly.

1. Options of the Metatrader4 trading platform.

Go to Tools – Options – Expert Advisors tab and check the options as it’s shown in the Leotrader manual.

In Windows 7 and Vista there is need to check if the Metatrader4 trading platform is run from the Administrator rights as the Options won’t be changed. If you use these operation systems, navigate the folder of the MT4 platform, right-click on the terminal.exe file, go to Compatibility tab and check Run as Administrator, then Apply and Ok.

2. The EA can’t connect to the server and can’t be authenticated.

I don’t have antivirus software installed on my PC so I can’t say if one or another antivirus program won’t block the connection of the EA, but anyways I’d advise to disable it. As to the firewall settings, I’d also recommend disable it, as the DLL file of Leotrader needs specific connection and in some cases firewall can be the reason. In Windows 7 and Vista, there are also advanced options of firewall, so you need to ensure that you also disabled firewall there. For unblocking the DLL file, you’ll need to find the DLL file in the MT4 folder, right-click on it and click on Unblock button, then OK. I suggest to recheck the Properties again as for different reasons the file can be blocked again, so in such case you’ll need to recheck all the system if other software is the reason of blocking.

If such tips don’t help, then the problem can be caused by the internet connection and ports which are blocked by ISP. In this case, I’d recommend using VPS service.

3. Error 126, error 127 or MT4 crashes.

I won’t review common issues like options in the MT4 and EA options. If you used the old version of the EA, for some issues the DLL file may not be replaced by the new one of 1.10 version if you used automated installer option. I had some MT4 crashes while trying to attach Leotrader to the chart without knowing the reasons, but I noticed that the new version of DLL file has larger size than the used in the MT4 folder and while I was trying to delete it, the system refused to do it, so I needed to restart my PC and then manually delete the old DLL and paste the new one.
I can’t say anything about error 127, but I solved the problem by reinstalling the MT4 platform.

I doubt that all Leotrader customers know about the issue that the EA needs to be attached to only one chart, but I can’t say about the compatibility with other Eas, so I advise to run the EA on different trading account.

4. Alert window and non-trading activity.

While attaching the EA I had the pop-up window with such messages: “Ignored “open command for signal…” and after contacting the EA support, I realized that it’s only a warning that LeotraderPro couldn’t open the trade with old trading signal, so I just closed the window and that’s all.

Non-trading or incorrect trading is usually caused by the incorrect risk level in the Inputs of the EA or the connection to the broker.

Hope, these tips can help you to solve the problems, which can occur on your PC, and you’ll be glad to use LeotraderPro EA.

    Unfortunately I can not explain in the greater detail than in this article. If you experience problems during installation you can try to use Service.
