Trend Filter - Quick poll

Whatever system you use to trade, it must surely have a decent filter to sort out trending from ranging markets. What is your favourite filter (indicator) and why?

I post this here in the mt4 forum rather that Trading Systems Forum since I'm an mt4 trader and interested in knowing which mt4 (Oscillating) filters traders favour.

A good filter would have been useful these past few weeks...

My momentum indicator is a 1 minute chart.

(edit: guess it's nothing to do with MT4, I'll be moving along now)

Nice chart... can you post indicators and template?

Thanks

This is Oanda, it's not possible to save the indicators and templates (and for the indicators, it's just moving average)

I trade daily Breakout, & it works for me.
Plenty of freedom to chose what you use!
Happy trading
