Any way to use extern values with scripts?

Currently I'm trying to make a script that allows me to input SL/Entry Price and it will automatically open a trade (a ton easier because I can let it calculate the lot sizes instead of me having to calculate it myself).

However, scripts do not seem to allow external values. Does anyone know if there's a possibility for this? I'm currently using an Expert Adviser that opens the trade on the Init() function. It's working fine except that I have to keep clicking on Live Trading to make it work and that's just effing annoying. If there's any way to make it so EAs don't need to have that live thingamagic clicked that would make me happy aswell.

I've looked at the thread where the buy/sell scripts are posted, but these seem to work only by modifying SL/Price in the script itself. I prefer using extern values because it's way easier instead of having to open/change/compile.

Here is what most of my scripts look like:
Inserted Code
 
#property show_inputs
 
 extern double    Lots=0.20;
 extern int       StopLoss=100;
 extern int       TakeProfit=200;
 extern int       MagicNum=999;

As cyber1 has shown above, extern values can be added to any script. The #property show_inputs is important if you want to see them prior to the script performing its routine.

Try opening your Tools > Options > Expert Advisors, and check the Allow Live Trading box there. Make sure they are enabled as well.
