this will change the color of the bars, that cross a higher aggregation average line.
only the bar that crosses the line is changed.
will draw small arrows, wedges, also.


Code:
# week_cross_on_day_00

def chartagg = getAggregationPeriod();
def chartmin = (chartagg/1000)/60;
#addlabel(1, "chartmin " + chartmin, color.magenta);

# ema20 , weekly
input avg1_agg = AggregationPeriod.week;
input avg1_len = 20;
input avg1_type =  AverageType.EXPONENTIAL;
def ma1 = MovingAverage(avg1_type, close(period = avg1_agg), avg1_len);

input show_average_line = yes;
plot z1 = if show_average_line then ma1 else...
