id personally be wary trading stocks long when the MACD is in negative territory even if it looks like crossing ---- risky business ---
wait for the MACD cross, and buy the low of the next cycle IF the low is higher than the previous low ---- much less risky cause yr punting with the trend
---- good luck with it
ps on this chart there would have been no long trades with the above scenario except maybe 4 --- but that was still risky cause we are still unsure whether the downtrend has reversed -- there were a cupla good shorts though!!
