Hey ec.... Yes, scripts are a one shot deal....
You produce scripts the same fashion as ea's just choose script when MetaEditor asks what you need to make....
Copy and paste the example code above and compile.... Then place it on any presentation chart.... Most scripts don't show the input signal, on this one switch trade to true....you'll see the orders put....
I always use scripts for putting large number of orders.... For safety....
Yes, you can do the same thing with ea's , just need some backup code to assure nothing has hung up....
I lost a few grand in a little while after when a loop retained placing orders at a live account.... It might have been worse...h
