If I have a short-term system that works well in "trendy" markets and not in sideways markets where it will get whipsawed to death, how would I best define a "trendy" market?
I need to somehow develop some strict criteria (maybe based on price action for the last x periods??) that tells me if the market for a given day is likely to be a trendy market or not??
Hope that makes sense.
Any ideas would be much appreciated.
