So anyone who thinks its alright to decompile software needs to take a good long hard look at their moral compass. So at best if it is not illegal then it is definitely immoral. This is the reason that many coders on Forums no longer post the source code mq4 so at least it makes it harder for those so inclined and thankfully the new MT4 appears at this stage to be very hard to crack. I can think of several examples of free software coded on Forums ( that have been cracked and passwords removed etc ) that are currently for sale for thousands of dollars by unscrupulous Forex/Binary websites. Some EX4 files can be converted using decompilers. If you have an EX4 file and if you’re looking to make changes to the algorithm, then you will need MQ4 file in order to do that. No thought goes into the huge amount of skill experience and time that goes into programming the indicators/ea's/scripts etc it all comes down to making a quick dollar out of someone else's hard work and knowledge. EX4 files is an executable file format which is created by compiling the source code and it is this file that run on the MT4 platform for trading automation and signals. EX4 TO MQ4 ORG Provides with the best quality of source code for MetaTrader 4 Expert Advisors, Indicators, Scripts.

There are a few coders on this forum who make design and code trading tools to sell and I have seen many examples of people who find nothing wrong in cracking the ex4 ( you only have to go onto eBay to see many examples of this ) and next thing you know that piece of software is for sell on some obscure website.
