Good posts dogpile.

I started to use ATR trailing stops because I needed something that would adjust to market conditions.

The ATR stop, by its very nature, adjusts to the volatility of the market.

The use of the inputs 10 and 3 may be a bit arbitrary although the logic is that calculating ATR over 10 bars is short enough to reflect current market conditions but long enough to give a "fair" picture. I keep the stop away by 3 ATRs because I find it far enough away to not be stopped olut unnecessarily most of the time yet close enough to get me out early enough at the end of a move. You might want to try numbers between 2 and 4 ( say every 0.25) if 3 doesn't suit. I'd be wary of over optimisation.
