The indicators aren't necessary. All you gotta do is throw up a couple lines.
Here we have 4 nice longs, net 4 each. (in green. shorts in red)
There were also technically two shorts, which would have been avoided if paying attention to s/r. Had you taken the short it was net 3 or a loss.
If you don't know where to start, start here! Don't be afraid to ask questions.
