WebThe Greedy Strategy was created to take advantage of gaps in either direction. It then accelerates into those gaps by playing momentum to the upside or downside. The strategy opens an initial order if there is a gap between the current open and the high or low of the previous bar. If open is greater than previous high, strategy goes long and if ...
