I just wanted to let you know that if you have downloaded any ea's from level 4 that you may want to re-download them with the newer file. The reason being that the magic number generator function that those ea's contain has a bug.
There are some combinations possible whereby if you are trading a currency on a daily chart and another currency on a 4 hour chart they could possible generate the same magic number and both be sharing the same trades. If you do not want to download the newer files you can simply go into the MagicNumber Generator function and add a zero. In the function it multiplies the pairNumber by 100. In the newer file it is multiplied by 1000 instead. This will stop the duplication.
