Quote from TheRumpledOne:
The COLORED MACD bars may make it even easier to see.
Bright green, means increasing above the line and Bright red measind decreasing below the line.
In other words, long on bright green, short on bright red.
Exit when color turns from bright to dark.
Sorry. That doesn't work.
Given that the earliest you could enter using your rules is on the SECOND bright green or red bars (because a bar can change from bright to dark during its creation based on how the market moves), the rules you described are illustrated here.
Each vertical line goes from the bar AFTER its trigger. We are assuming perfect fills at the opening of each candle.
Horizontal lines have been drawn at the entry price for each position (the opening of green and red candles associated with the triggering bars of the MACD).
This strategy is not profitable, especially after commissions, for the chart posted.
edit - the strategy would be profitable if one could enter at the bigging of the candle
which causes the MACD signal bars to change to bright or dark, but obviously that's impossible because you would be entering before confirmation.
A lot of charts that look amazing are realized to be unprofitable after you consider when you can actually enter.
edit - sorry this chart is really sloppy because I made it in a hurry, but you can see of the long trades, there are 3 profitable and 10 unprofitable, and of the short trades, one profitable and 1 unprofitable. Add up the ticks and subtract commissions (or not) and it's not profitable.
