The current MACD and Histogram values are available to the graphs, but are not available for doing searches or creating custom fields. It would be more innovated and a better tool to accommodate a larger portfolio of styles if one could search using the actual values. Example: MACD < 0, or MACD between -1 and 0. Or to add more power, something like MACD < 0 and trending higher. Flexibility would be a good enhancement.
