Yes i have the emails saved i'll have to go back to that one and check it out. Elder states that divergences are the strongest signal in technical analysis, and I believe that it's certainly one of the strongest. So, if this strong signal fails. Then a signal failure of a strong signal is then even stronger. And what he advises and i would if playing this type of move is using a stop reverse order. If your broker permits of course. There for, if the strongest signal fails, then it produces a stronger signal using a stop reverse would see you through that signal failure and able to profit even though the move went in the opposite direction.
The idea of divergences as with most approaches labled trend following, is to wait for confirmation in price first. So maybe a 13EMA with a two day close of the EMA inside the price. This works for me. Actually waiting for the MACD line (blue) to cross above the red. I know sometimes this means not getting the best entry, but it does then confirm the stock is moving in your favor. Look for high volume on upward moves and closes higher than the previous close on a two or three day basis. And a nice tip for our style that i come across, try plotting a 65,130EMA on a daily. Reason? This is a close to having a weekly 13and 26EMA you can get. Remember? factor of five. This makes what i like to call a value area. It works well on trending stocks and only consider going long in this value band. I hope that answers some questions. But, feel free to pick my brain cell again.
