If you are trading short term expiry's I suggest you try and find patterns with indicators rather than signals with arrows. The problem with arrows/dots/colors is that its affected by volume and changes in short term volume can be very unpredictable, like when news hits, throws off the calculations in your indicator that produces the signal.

It's in my opinion that you look for patterns during trending times of a market and non trending times-patterns when volume is worth trading and when it is not.

But that's just half the battle - and my advice is to use the scanner found in the trix thread. I would say the best I used in terms of finding trending pairs. Better than any CSM's with no lag if you set it up properly.

When to enter is the trade is the half of the battle but is easy if you understand how candles work on MTF's.
