That's very odd, I find it works every time, I wait for the crossover and then go against the trend! that's right, ignore it, hence spooking the market, try it, if it didn't work, I'll give you your money back.
Fast Stochastics is quite neat as well, just wait for the crossover then follow it, so to re-cap go against MACD and follow Stochastics. Bob's your uncle!
