cash - Since both lines are pointing higher it is bullish if they are broadening, and bearish if they are narrowing. (If they were narrowing, it would be a "rising wedge")
If both lines were pointing downward, it would be the opposite.
After a long advance, if the top line is pointing up, and the bottom line is pointing down, it is a potential "broadening top" (bearish). If confirmed by a breach of the lower line, it signals a measured move down of the distance between the two lines.
After a long decline, if the top line is pointing up, and the bottom line is relatively level, it is a "broadening bottom" (bullish).
Hope this helps.
