Hello trader9,

Thank you for writing in.

The logic for coloring the cell will be done through the Market Analyzer itself.

However, we'll need to program some logic into your indicator in order to tell the Market Analyzer to change the cell color.

As an example:

protected override void OnBarUpdate()
{
     if (Close[0] >= PriorDayOHLC().PriorHigh[0]) // if the last price is more than or equal to prior day high
          Value.Set(1); // set plot value to 1
     else if (Close[0] <= PriorDayOHLC().PriorLow[0]) // else if the last price is less than or equal to prior day low
          Value.Set(-1); // set plot value to 0
}

Once you have added the indicator to the Market Analyzer, you'll want to set up cell conditions for your plot.

You'll need two conditions for the example above.

One condition checks if the value equals 1. The other checks if the value equals -1.

I would highly suggest taking a look at the help guide at this link for some helpful educational resources on programming with NinjaScript: https://ninjatrader.com/support/help..._resources.htm

Additionally, information about creating cell conditions within the Market Analyzer can be found here: https://ninjatrader.com/support/help..._and_filte.htm

Please, let us know if we may be of further assistance.

market analyzer shows only 1 as value

Hi,
I have created indicator based on your instructions, it plots perfectly in chart as 1 and -1 (screenshot attached), but when I load that in market analyzer with 1 min as data series it only displays 1 as value in cell(although it's -1 in chart) , I have tried to load number of symbol in market analyzer and its plots 1 in each cell, I have not reached to cell filter yet, but it should plot same as in chart as value. Am I missing something ?

Hello trader9,

Thank you for your post.

In the Market Analyzer you have the '# of bars to look back' property which allows you to set the number of bars to calculate over. You access this when right clicking in the Market Analyzer and selecting Properties.
In addition, the indicator column itself has an option called '# of bars to look back' that would need to be set as well. Accessed by right clicking in the Market Analyzer > select Columns > and select your indicator column.

The chart has the option 'Load data based on' which is usually set to 'Days to Load'. You would need to give the Market Analyzer as many bars as the chart to see the same value. You can change the chart to 'Bars to Load' by right clicking in the chart > selecting Data Series > set 'Load data based on' to 'Bars to Load' and then set the number of bars that you wish to use and that match the Market Analyzer.

Please let me know if you have any questions.
