Very useful information Billy which makes me think of J. Welles Wilder's parabolic system (Stop and Reverse or SAR) presumably just on the long side.

I presume that the same exponential approach is valid when one is short? Yes or No
or the model is different for a short trade because your research has shown a different optimal stop strategy when short.
