I have also been working on an alternative entry working with the same double MACD strategy.
As I mentioned above in my NO TRADE ideas, you would not take a trade in line with the bias (MACD below Signal - SHORT or MACD above Signal - LONG) when the MACD is pointing below horizontal for long or above horizontal for short (*re-read NO TRADE rule #2) as these result in fewer successful trades.
which got me checking and actually these have a 70% chance of failure, BUT and it's a big BUT. This means they have a 70% chance of success going against the bias.
If you use these opportunities where the MACD is returning to the signal line and wait for a crossover to happen on the shorter time frame, using all of the usual rules to setup a trade.
#1, Shorter time frame crossover (above zero for short, below zero for long)
#2, Candles closing over the 200 period EMA.
But with some exceptions.
Lower risk position, if you usually trade with more than 1% of your portfolio then half it for these positions.
Stop loss set at recent swing rather than overall swing.
Hard take profit at 1.5xR.
It's a nice way to scalp some pips but wouldn't use it as a stand alone strategy.
