MACD Prediction for Amibroker (AFL)

I have not written this formula.
I found this formula in one of the blog.
This is a Dimitris formula Contributed to the blog by Dick H.

The principle of the code is simple : We suppose that the next ROC changes from -25% to +25% AND we calculate the necessary ROC for a higher MACD.
Example1 : On Oct29 [point P1] AMZN would have a higher MACD if the next ROC would be more than +1.30%. The next Day, Nov1, AMZN closed at +2.80% AND the MACD was higher indeed. It was known [AND almost safe] before the end of the Nov1 session, that AMZN was gaining more than +1.30%.
Example2 : On Jan4 [point P2] the ^NDX needed a +2.70% to change the MACD downtrend. The most probable was to see lower MACD values…
