I am a newbie and don't know anything about programming. So here it goes -what is a .mq4 file, what does it do and where do I put it. Also, what's the difference between an mq4 file and a .ex4. By playing around with it I have noticed that some .mq4 will also place trades. Any info is much appreciated.
You guys are so knowledgeable and helpful, giving so generously of your time.
Thanks in advance.
