can someone please explain

 
Hi can anyone explain this part of the code in the "macd sample ea " . .... Important notice: to exclude insignificant changes of the MACD indicator (small 'hillocks' on the chart) from our analysis, we introduce an additional measure of controlling the size of the plotted 'hillocks' as follows: the indicator size should be at least 5 units of the minimum price (5*Point, which for USD/CHF = 0. 0005 and for USD/JPY = 0.05). What are they actually measuring ? Is it just the level the macd reaches ? thanks in advance
 
IF you look at the idea behind MACD indicator then you understand that value between two moving averages can be very small. Sometimes the price isn't moving anywhere, going a little up to come a little down and so some time. Then the MACD indicator is near zero level going and coming back. This time you can consider as dead time. If you make a analysis then those dead zones are changing values but giving no information. moving average goes down but there is no movement. Looks like those folks wants to exclude that kind of dead zone from analysis to get more accurate data.

The level of 5 pips seems a little small to give an reasonable effect!
