TRAP: Topping from Below
As I wrote above, the top-down and the bottom-up appoaches need not be mutually exclusive.
The top-down approach allows us to look back in time and determine where the points of inflection will most likely be. Even though there's no bullet-proof way to know in advance where the given trend will ultimately begin and end, we can use previous support and resistance to forecast with reasonable accuracy. Like street signs, these areas serve as sign posts to help us maneuver throughout the day. Just as it's a good idea to know precisely where your destination is before embarking on a trip, it's always ideal to mark the areas of reversal well in advance.
However, there's no absolute guarantee that prices can or will reach these areas, otherwise we would all be filthy rich by now. There's no 100% certainty in this game. On the other hand, trading is centered around the theme of expectation or probability. We take trades with highest probability of success and we dump trades with the highest probability of failure. This is where the bottom-up approach comes into play.
The bottom-up appoach allows us to
confirm whether those inflection points will in fact stand up to our expectations. Going back to our trip analogy, it's important to note that locating our destination on the map is one thing; actually getting there is another. For example, I know that Mount Everest is located in the Himalaya. But that doesn't mean I know how to climb to the peak of the mountain. In order to climb to the top, I would need to obtain a good understanding of various mountaineering techniques, such as terrain and weather. Likewise, with the bottom-up approach, our aim is to monitor various price behaviors through the lens of
momentum and
time, which are encapsulated in
price swings, in order to see whether they confirm to our forecasts.
