Market Analyer vs Chart Indicator Differences

[dkrumholz]

I have a chart with an indicator that exposes a value and draws an arrow under certain condiitons. The chart is linked with a market analyzer window that has a column for the same indicator. The problem is that the indiator on the chart and the indicator called by the market analyzer are returning different values.

I have determined that the problem is that the chart has a data series that can be told to only load n days of data. The market analyzer on the other hand can only be set to look back 256 bars or an infinite number of bars. So if I set the chart data series to 256 days and the indicator called by the analyzer to look back 256 bars, where each bar is one day, I can get the same values.

Shouldn't the market analyzer also be able to be set to only load n days of data? Without that setting one needs to adjust the chart to only have 256 bars of data. Is that correct? Am I overlooking an alternate solution that prevents the discrepancy?

Hello dkrumholz,

The Market Analyzer, unlike a chart, is mainly used for real-time market scanning for multiple instruments, therefore a number of days to load would not be needed.

Yes, you could set the Maximum bars look back to 256 on each of the Market Analyzer and the Charting window.

The other options to check would is to check the Calculate on bar close is set to false if you are using the Market Analyzer as the indicator will be updated every tick.

Please note that exposing an indicator value that is not a plot would be used for access from other indicators or strategies.

Please let me know if I can be of further assistance.

Since I am using the market analyzer for market scanning and I want the scan to match the chart that is linked - I think do need that setting. I don't understand how the market analyzer being used for real time scanning is justification for omitting that setting. I don't see how realtime scanning obviates the need for the setting. Can you explain how the one follows from the other? It doesn't yet make sense to me.

Hello dkrumholz,

To start lets make sure you are getting the same values on each one. If you set Calculate on bar close and the Maximum bars look back to 256 on both the Market Analyzer, and the Chart does you indicator have the same value?

As for the Market Analyzer, you will want to use the right tool for the job, for example to look back at data for a specific number of day the best tool would be a chart. With that said, you still do have the option to set the Maximum number of bars to Infinite so you still can access to the full series so you can look back farther than just 256 bars.

I must apologize. The setting is there - almost. I don't know why I keep overlooking it. The indicator when called from the market analyzer has a setting for number of bars to look back. Not the same as the chart which has a value set in days but if you work with a daily chart it happens to work out.

As a wish list item - the two settings should be changed to have identical units. The indicator when called from the market analyzer should probably have number of days to look back (like the chart's data series) instead of number of bars to look back.
