I use the classic patterns for locating roadworthy vehicles, vehicles that are more likely than not to get me where I want to go.
I use the environment in my time frame (intraday pit session) as a roadmap for determining if there's a place worth going and if my vehicle is more likely than not to get there before encountering serious obstacles.
Sometimes obstacles arise that weren't on the map and I may decide to stop or reverse the other way to avoid serious damage.
When I see a classic pattern in an environment that tells me the road looks well-paved and it's unlikely any obstacles will arise for at least the next N ticks of travel, I go for a drive.
I know that in a strong downtrend if the pullback is shallow and there's a key level like that daily lower trend line in CL Friday around 92.90, I can very likely drive a long way without obstacles until that point. And every set of eyes looking at the chart sees the same thing: 92.90 is a great value with low risk for buyers, so if I want to buy I'll wait for that bargain price, if I can't stomach that kind of adverse excursion on my long positions I'll sell long before then, and if I want to make money to the short side, I'll sell every pullback until price gets there.
