hi there

this already compiled and you don't need to compile it
its an .ex4 file. All you have to do is place it in your experts folder,
for example C:\Program Files\FXDD - MetaTrader 4\experts then restart MT4 and you see it in the experts folder just attach it to the chart and it should work. BTW you will see it Grayed out as its only the compiled version and without the source code but it will still work

hope that helped
