Sorry but that answer is just not good enough. If checking whether or not some TA analysis will be useful it should be back tested on the instrument ie. CTT that you wish to trade. Clearly it was worse than useless last time so whether or not it worked on another instrument is less relevant. In fact it would be interesting out of all the crosses (50 and 200) on CTT how many times it was a profitable or loss making strategy and by how much. My quick analysis points to only losses for the past 5 years so not a strategy to be considered let alone relied on.
