Most times throughout our database you will notice each indicator has 2 different extensions .MQ4 & .EX4
The .MQ4 is the source code of the Indicator. This is the code you could alter (if you know mq4 coding) to change the desired affect of the actual indicator.
The .EX4 is the same indicator but it has been compiled so that it will load up and work within MetaTrader. This also can protect the intilectual property of the writter if they do not want it altered at all.
In most cases we will supply both the .MQ4 and .EX4 version of each indicator within our Database for your use.
