Looking for dynamic stop losses indicator

Sometime ago, I saw a system that had dynamic stop losses ( looking like parabolic SAR dots)......

If market was slow, it wouldnt really move, BUT as the market started moving, it closed up and the faster it moved, it closed up.

Does anyone have anything like that I can have a look at

Thanks in advance

This may be the one you're looking for. You may wish to set the ATR to around 5-6.
