Invalid Statement.. Why?

[Mocnarf1]

Why would this statement be invalid in a Study?
close + 0.20 < SimpleMovingAvg("length" = 9)."SMA"[0];

The ThinkScript Forum on TOS suggested using AverageType so this is what I have
close + 0.25 < averageType.SIMPLE

How do I change the averageType say to 21 or 42?
And does averageType default to 9?

In a study you need a def or plot statement or labels or bubbles. I added a def x to you code and it works.

So see below some of these options and how to use averagetype.

def x = close + 0.20 < SimpleMovingAvg("length" = 9)."SMA"[0];

AddLabel(1, SimpleMovingAvg("length" = 9)."SMA"[0], Color.WHITE);
AddChartBubble(1, low, SimpleMovingAvg("length" = 9)."SMA"[0], Color.GRAY, no);

input length  = 9;
input averagetype = AverageType.SIMPLE;
plot y = MovingAverage(averagetype, close, length);

I assume the statements evaluate to either true or false, 1 or 0 Correct?
I will try out your suggestion.

I have also been trying this, See any problem with it?

def sell =
close > Average(close - 0.2, 9)
and close > Average(close, 21) ;

What you posted in #1 will work in a scanner as is returning a 1/0. In a study though you need to do what I suggested abpve.

Likewise, what you posted above is valid in a study, but a study needs a plot, or label or bubble in addition to be a valid study. If you want to use it in the scanner then the following will work returning 1/0

plot sell =
close > Average(close - 0.2, 9)
and close > Average(close, 21) ;

or

close > Average(close - 0.2, 9) and close > Average(close, 21)
