Hello guys !
I am a web developer and I have a good sense of logic programming . But I do not know much of MQL .
Based on other indicators , developed one that gives great results in Binary Options , and would like to market it. However , I can not do the following:
- Set password from decompiling
- Set expiration date to offer trial version
- Set number of mt4 user , for possible buyers.

I would like your help with practical examples , and to send the file via e- mail (ie , will win the indicator for free) , for those who are available to help me . Thank you
