Couple of newbie questions...
How do I get the Exponential moving average of the prior day / time period ?
For example, something like:=

Avg1 = XAverage(close,40);
And then we can compare Avg1 with Avg1[1]...
(Where Avg1 is current and Avg1[1] is prior)

And, how can I setup a stop loss order ? I see that there is a StopMarketOrder class,
Is that what I have to use ?
I would like to set a stop using the average true range.

I am using the clone of the exponential moving average cross-over
strategy as a starting point.
