Secrets of MetaTrader 4 Client Terminal: File Library in MetaEditor

When creating custom programs, code editor is of great importance. The more functions are available in the editor, the faster and more convenient is creation of the program. Many programs are created on basis of an already existing code. Do you use an indicator or a script that does not fully suit your purposes? Download the code of this program from our website and customize it for yourselves.

45	criss73 2006.07.20 18:38 ok stringo, i managed to write in the codes and compile them but i want to be able to add lots. in the "input" all i can do is change the ema values.

45	criss73 2006.07.20 21:03 another thing stringo, i want to add Gridsize,Gridstep and Extendgrid! thnx

criss73 2006.07.21 06:30

hey stringo, forget about the Gridsize, Gridstep, and Extendgrid. i still want to know how to code the lots but, also, say the trend is up and i open my charts and turn on the EA, i want it to automatically enter me in the trade in the direction of the ema average; which is in this ex., up. do you know what i mean?

thnx
