Like all the Ichimoku elements treated so far, Senkou B should have the most applicability in identifying current and future support/resistance areas. The higher the time frame studied, the more important the support area is.
One interesting situation most of the traders fail to address is the Chinkou line/Senkou B interpretation. Given the fact that Chinkou is plotted 26 periods before the current price levels, by the time when it is reaching the Senkou B usually price is bouncing (if the previous move is pointed to the upside) or it is strongly rejected (if the previous move is pointed to the downside). This is what most of the traders fail to do when looking at the Ichimoku elements and trading with them: they don’t know what to do with the Chinkou, considering it to be useless. Well, this is just the first interpretation of it, treating it in relation with the base or the top of the cloud (the Senkou B line).
For example, if price is bullish, meaning the cloud is green but price is in an area of consolidation, then by the time Chinkou reaches the base of the cloud in this case (the Senkou B) a possible bounce should be expected. The very opposite is valid as well. If price is bearish, meaning the cloud is red but price is in an area of consolidation, then by the time Chinkou reaches the top of the cloud (the Senkou B), a possible rejection should be expected. Again, the higher the time frame, the stronger the support/resistance area.
The recording that comes with this sub chapter deals with all of the above, showing you concrete examples on how to use the top/base of the cloud.
