you first have to define the word "worth". It means different things to different people. For some, its all about the money. The other extreme could be about beating the "system". Finally if its money then the question should be how much is a pip worth? Would we say a pip = 0.10 cents worth the time? What about a year down the lane where 1 pip = USD 20.00. Is it worth an individuals time? When it gets to say 1 pip = 200 USD ?? What now?? As I said, it all depends. P/S what might be overbought or oversold to some might just be the signal to enter for the others. It all depends.

If it gives you a lot of profits and improves your trading knowledge, then it is worthy.
