BarsArray[0].GetHigh(0) and High[0] values different?

[bltdavid]

What am I missing?

GetHigh() is using an array index, where '0' is the first
bar as seen on the far left of the chart.

High[] is using a series index, where '0' is adjusted to
always mean the most recently closed bar, on the far
right of the chart. A series index has a special name,
it's called a BarsAgo index.

When a new bar is closed, it's high value is accessible
via GetHigh(CurrentBar) or High[0].

The high value of the very first bar on the far left is always
accessible via GetHigh(0) or High[CurrentBar].

Careful ...
High[CurrentBar] reads like a misnomer -- so you must
first understand what the BarsAgo index means, and
then you'll understand why the series syntax is most often
used to 'look back' at historical bars.

(Hint: The 'why' is probably due to ease of programming.)

Good reading here, here, and here.

Hello waltS,

Yes that would be expected, those methods are not alike. One takes a BarsAgo and one takes a Index, BarsAgo and Index are not the same concept. 0 index is the first bar on the chart, 0 BarsAgo relates to where you are in processing right now.

I am coding a pivot with a source of a series.

When I assign the series values using:

tradeH[0] = BarsArray[0].GetHigh(0);

I have very different results by assigning the the values using:

 tradeH[0] = High[0];

I would expect that "BarsArray[0].GetHigh(0)" would return the same value as "High[0]"

What am I missing?
