English to Portuguese Other Business/Commerce (general)

Sometimes, however, "skyrocket" trends evidence no such gradual increase of Resistance as they proceed, showing no tendency to lose momentum, but rather continue to speed up until, suddenly, they hit a stone wall of supply (or, in cases of a decline, demand) and are brought to an abrupt end by a day of terrific trading volume. In such moves, a wide gap may appear at the very end, i.e., between the next to the last and the last day of the move. This gets the name of Exhaustion Gap because the trend seems thereby to have exhausted itself in one final leaping spurt.
