BarsArray[] Usage Question

[borland]

Normally, a simple moving average based on closing price, however if wanting it based on High from a BarsArray[], which of these is correct....

SMA(BarsArray[1].High, 20)[0]

SMA(BarsArray[1], 20).High[0]

SMA(BarsArray[1],20)[0].High

Couldn't find any examples. Thanks

borland, you could start working with Highs[barsArrayIndex][barsAgo], which is a multi-dimensional array of all bars' highs. There is an equivalent array for all of the following: Opens, Lows, Closes, Volumes, and Times.

Thanks Austin,

Then it must be this ...

SMA(Highs[1],20)[0]

for SMA based on intrabar high, and these

SMA(BarsArray[1],20)[0]
SMA(Closes[1],20)[0]

for SMA based on closing bar price.

I now see we have Highs[], Lows[], Closes[], Opens[].

So, since Closes[] is identical to BarsArray[] when used with SMA. Why is there a BarsArray[] method?

Correct, BarsArray[0] would for example equal Close[0] - it returns just the dataseries for the specifc bars object pointed to, while for example Closes etc would also offer a second parameter for referencing past index values of the bars object.
