At any point where a=b the function is discontinuous, so it doesn't have a derivative there. It has attributes: reference: the number to compare the value with, relative: whether that difference is absolute or relative, (increasing|decreasing).color: color to be used for positive or decreasing delta, (increasing|decreasing).symbol: symbol displayed on the left of the delta, position: position relative to `number` (either top, left, bottom, right), prefix: a string to appear before the delta, suffix: a string to appear after the delta. So you can just return True on the first valid result: def I (feat,F): for i in F: if np.all (i==feat): return True return False. A shorter force index can be used to determine the short-term trend, while a longer force index, for example, a 100-day force index can be used to determine the long-term trend in prices.
