How do I modify Pivot indicator to only use Historical Data

[JerryWar]

I use a pivot indicator which is the same as the Built in Ninja Floor Pivot indicator.

1) I use it with daily bars set as the input setting.
2) I use the kinetick data feed to populate daily charts and obtain the correct high , Low and settlement closes. and then those charts are closed as I now have the historical data I need for the day.
3) If I uncheck "Get Data drom Server( if available)" it works but If I leave it checked My real time feed will write over the Daily History data collected even tho the daily charts are closed because of the data method that reads the data in the indicator. Note: The Pivot indicator is applied to intraday tick charts.

So it works to some degree with this limitation of unchecking "Get data from Server" But
The major problem with this is that I have another indicator that doesn't work properly unless "Get data from Server ( if available )" is checked.

So I would like to modify the Pivot indicator to only use Historical data and to not Fetch any data from the server that would overwrite the daily history data. I can read and write "C" code but I don't know the internals and the appropriate commands Functions in Ninja to make this modification if possible. I have tried commenting and changing sections I thought might correct it but all to no avail. Can someone either give me some direction on this or provide some links to code that will only read the historical data without pulling in data from the server.

The pivot indicator is built in and you can examine the code, so I did not post it.

Jerry, please add in this line at the very top of the OnBarUpdate() method:
if (!Historical) return;

This will basically force your indicator to skip over all data that is not historical.

That's awesome, I have made the change and will test it on Monday when real time data starts coming in.

thanks.

This did not work, I have just tried it The close of Friday got written over with "Get data from Server" Checked and no daily charts up with your code line added. below is a snippet of what I added. Do you have any other ideas ?

protected override void OnBarUpdate()
{
// Don't update unless historical data.
//
if (!Historical)
return;
if (Bars == null)
return;
if (!Bars.BarsType.IsIntraday && Bars.Period.Id != PeriodType.Day)
return;

Jerry, I am not sure if this is actually possible upon reconsideration. I will have someone get back to you tomorrow.

Hi Jerry, this is unfortunately not possible without changing the internal workings of the per default shipped code as it would asyncronously load the needed series in the GetBarsNow() method outside of OnBarUpdate(). If you change to code to not trigger this method to update the daily base date it should come close to what you seek here.

Hi good to hear from you again. I understand what your saying except that as when you remove the call to GetBarsNow() it looks like it no longer fills the DailyBars Data structure so there is no data to calculate the pivots. How do I retrieve the history in this case. I tried playing with the parameters in Getbars but got no where and I could not find any definition on your site.That appears to be the offending line of code in the method. Can the parameters be tweaked or does there need be a different method to read the history. If so could you point me in the right direction ?

Thanks
Jerry

Hi Jerry - then I'm not following what you attempt to do - if you remove the GetBarsNow it should not grab any backfill data - which is what you seemd to seek here according to your first post? The method used is unfortunately not documented and therefore not supported, it's a custom method only designed for the use in this exact script.

Let me restate the issue.
I use kinetick EOD data to supply the daily data for the pivots indicator. I load this indicator on an intraday chart. So each morning I open a daily chart while connected to kinetick and update the daily data. Then close that Daily workspace and close the kinetick connection. I then connect to my broker. With the pivots indicator, If you don't uncheck Get data from Server ( if available ) Even tho a Daily chart is not open it will overwrite the EOD bars that were saved from Kinetick. I think Because of the way the indicator is written Ninja will use intraday data from the broker to calculate eroneous EOD bars and write over the last one or two daily history bars loaded from Kinetick messing up the pivots. The downside of unchecking Get data from server is that Other indicators do not work properly.

You are correct when you say eliminating GetbarsNow will stop the backfill of the history data. It does. But it also no longer plots the pivots because I think that it is also how it transfers the data from the history database to the memory structure used to calculate the pivots. So what I am asking is how do I load data from the history database(data that is already there) for calculation of the pivots without GetbarsNow.

Thanks

Thanks for the clarification Jerry, have you tried simply staying connected to Kinetick as primary connection and then connecting to your broker second and working with 'Get Data From Server' - this way for any request triggered the daily bars should still come from Kinetick where as realtime data not available from it would come from the broker connection.
