This guy in comments says true. When I had traded, the slow execution was since I started. I immediately withdrawn funds and never traded with them. They didn't even split same direction positions. I had to open only one trade whether it's buy or sell. My second broker was much less recognizable but I have never faced such a slow trading through mt4. Such a bad experience!
Platform disconnects many times while my other brokers are still running smoothly. I was told by a friend that as soon as you start making some good money, they will start slowing execution speed on your account. Funny how this has started to happen on my account now. In the group of thieves!
