Hi,
I've looked at your indicators, and am fairly confident I can do this. I will be reverse engineering it, not decompiling it, and you'll receive the mq4 source file. In future, you need to request for the source file as decompiling code isn't as easy as it used to be, and requires a lot more resources. If you know the exact rules of how indicator 4 is using values from indicators 1-3, then this will go much smoother as I won't have to guess as much.
I have over a decade of experience in coding trading systems, and spent the last 8 years focused on developing in mql4/5
for the metatrader platform. Although relatively new to this site, I am definitely qualified for the job.
Thanks for considering me.
Cheers,
Shi Jun
