Why won't this calculate?

[user721]

Hi;

I'm trying to make this work in MarketAnalyzer.

I want to get the value of the 200sma 30 days ago.

This won't calculate (just get all zeros):

DfmLkBktoMA200.Set((SMA(Close, 200)[0] - SMA(Close, 200) [30]) / Close[0] * 100);

But this does (so I think that says the problem is not somewhere else):

DfmLkBktoMA200.Set((SMA(Close, 200)[0] - 1) / Close[0] * 100);


Even when I put it in its own indicator it only displays zeros in Market Analyzer:

Plot0.Set(SMA(Close, 200) [30]);

Thanks

never used market analyzer,

but just some general ideas to try: I'm guessing that bar[30] of 200 day sma would need days loaded > 230?.. i'm sure you have more than that, right?



Does
DfmLkBktoMA200.Set((SMA(Close, 200)[5] - 1) / Close[0] * 100);
work?


DfmLkBktoMA200.Set((SMA(Close, 200)[1]); ?
DfmLkBktoMA200.Set((SMA(Close, 200)[30]); ?

Thanks

Yes I have 300 bars loaded and maximum bars set to infinite

Which one did you set to the 300 bars lookback, the general or indicator column one?

Thanks,

[user721]

I have set both to 1000. Still the same, no look back yields results but when I change it to look back 1, 10, or 30 days it just comes up all zeros. thanks

What happens if you try to chart this indicator then? Would the behavior be any different? Do you see any log errors in the Control Center?

Thanks,

Same behavior in a chart.

Here is the error from the Log:

Error on calling 'OnBarUpdate' method for indicator 'aazTest' on bar 0: You are accessing an index with a value that is invalid since its out of range. I.E. accessing a series [barsAgo] with a value of 5 when there are only 4 bars on the chart.

I tried loading 1000 bars in the Data Series but to no avail. thanks

You likely do not have defined a proper CurrentBars check for your script then :
