Metatrader 4 coding

Dear Sirs, I have a couple of projects for coding in Metatrader. But I want to start with converting a simple code from amibroker to metaserver. This is the code in Ambroker: stmove=(C-MA(C,20))/StDev(C,20); Plot(stmove,"Standard Deviation Move",colorBlue,styleStaircase); Plot(1.8,"",colorRed,styleLine); Plot(-1.8,"",colorRed,styleLine); I would like to have this converted to metatrader 4. After this project I would like to make a new and bigger project with by writing a system ( with this indicator included) The programmer who offers me the best service / price also will have a preference for the bigger project. gr Gerard
