How Convert Script Commands into a File for MT4

Hi Everyone,

At times I try to download an indicator or script and I’m presented with script commands such as:

if(Ask>iMA(NULL,PERIOD_D1,MA,MAShift,MAMethod,MAAppliedTo,0)
{
if(Ask>iMA(NULL,PERIOD_H1,MA,MAShift,MAMethod,MAAppliedTo,0)
{
if(Ask>iMA(NULL,0,MA,MAShift,MAMethod,MAAppliedTo,0)
{
ORDERSEND
}
}
}

How do I convert it into an .ex4 file for placement into MQL4>Indicators or Scripts in MT4 or otherwise insert it?

Thanks,
Norm
