I am a relative newcomer and I have been using a system which uses MACD crossovers + price/volume changes to search for stock. I then use a chart that includes MACD + histogram and Twiggs + ROC to choose when to buy and sell. The signals are a simultaneous rise in Twiggs and ROC + a change in histogram
trend (or MACD crossover) for Buy Signal and simultaneous Falls + change in histogram trend for the sell signal. (See chart) I would be interested in any comments you may have on this system. The MACD crossover is generally too late as a signal - hence the use of the histogram trend.
