help required compiling and making .mq4 file.

[[Deleted]]

I have not used meta editor of MT4 for compiling and making .mq4 file.

I have a code which plots BB with deviation in decimal points. Pl. convert it to .mq4 file

Since there are no slaves here, you have only three choices: Search for it, learn to code it, or pay someone. We're not going to code it FOR you. We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem.
