Hi skan
There are a number of different ways to do this but one way would be to use the "Print" command; you could also use an "Alert" it depends on why you want to check.
If you are still developing and testing a strategy then you would most likely use the "Print" command. You'd then check the Easy Language Output Bar to see the results. You can also output to a file on your computer.
If you are trading your system live then you'd use the "Alert" command so that you can be notified when a trade takes place.
