 As discussed by David Varadi on his blog, the MMDI is simply a MACD where the short term average is replaced by the median for the same period. So for example, the standard 12,26 MACD would become the median price for the last 12 bars minus the average for the last 26. He also mentions that he prefers to smooth the the resulting difference line using a 2-5 period SMA/EMA. I'd like to recreate this indicator in SF4 is possible.

So,

median of the last “n” days - average of the last “n” days = D

D is then smoothed and plotted. Can this be done?

 You should be able to Open an attached Indicator directly into a running copy of StockFinder (and save it from within StockFinder if desired).

 Bruce,


How might I write a PCF for the median price crossing its 3 ema

This is my attempt...

((H + L) / 2) > XAVGC3 AND ((H1 + L1) / 2) < XAVGC3.1

Thank you in advance!

 Quiktdr,
As long as you are aware that your use of the term median price is different than what is discussed in the topic, I would suspect what you want is median price crossing up its own 3-Period Exponential Moving Average:

H + L > XAVGH3 + XAVGL3 AND H1 + L1 <= XAVGH3.1 + XAVGL3.1
