I am trying to figure out how to plot 2 simple moving averages on a lower chart. I would like to be able to input the lengths of each and the aggregation period for the lower chart. Can someone help me, I am just learning the syntax and am having a hard time writing this seemingly simple script. Thank you

Solution
I am not sure if this is exactly what you're asking about, but it should at least be enough to help you figure out the rest. The aggregation you select can not be smaller than the chart's aggregation, so I added a thing to fix it in that event, and a little warning pops up. It will just default to the chart's aggregation in that case.

Code:
``````declare lower;
input P1 = 20;
input p2 = 50;
input Agg = AggregationPeriod.DAY;
def FixAgg = Max(Agg,GetAggregationPeriod());
plot MA1 = simpleMovingAvg(close(period = fixAgg), p1);
plot MA2 = simpleMovingAvg(close(period = fixAgg), p2);
AddLabel(FixAgg != Agg, " ERROR ",GetColor(Random() * 10));``````
