Think or Swim indicator converted to Ninjatrader

Doesn't NT8 already have this called Buy Sell Volume or Buy Sell Pressure?

Doesn't NT8 already have this called Buy Sell Volume or Buy Sell Pressure?

Kind of - but from what I see they're separate indicators, so taking up more screen "real estate" & are harder to read at a glance. The one I'm looking for would allow me to eliminate my current volume (bars) indicator, and is very easy to comprehend pressure direction at a glance with it changing the bar colour.

But then I'm new at this, maybe I'm not understanding the NT8 built in one correctly.

Besides these already mentioned indicators, you can also take a look at Ninja Trader's built in Order Flow Cumulative Delta indicator.

This indicator allows you to change bar colors as well in order to determine pressure direction.

Hope this helps...

Yes that us this one. However someone suggested this as a better one. If i can get a NT of either it�d be great.

If still looking, here's a quick conversion. There's an input towards the end "length1" that doesn't seem to be used, unless I'm missing something. Anyway, have a look and see if results match ToS.

Code

        {
            // make sure to always start fresh values to calculate new min/max values
            double tmpMin = double.MaxValue;
            double tmpMax = double.MinValue;

            // For performance optimization, only loop through what is viewable on the chart
            for (int index = ChartBars.FromIndex; index <= ChartBars.ToIndex; index++)
            {
                // since using Close[0] is not guaranteed to be in sync
                // retrieve "Close" value at the current viewable range index
                double plotValue = Volumes[0].GetValueAt(index);

                // return min/max of close value
                tmpMin = Math.Min(tmpMin, plotValue);
                tmpMax = Math.Max(tmpMax, plotValue);
            }

            // Finally, set the minimum and maximum Y-Axis values to +/- 50 ticks from the primary close value
            MinValue = tmpMin; // -50 * TickSize;
            MaxValue = tmpMax; // +50 * TickSize;

Thanks.

However, when I attempt to import this into my (NT8) I get this message:

Warning
This NinjaScript archive was made from an older, incompatible version of NinjaTrader

& it fails to import/load.

(I took your file, sent to .zip, then tried to import the zip folder)

Do I have the process right?

Thanks,

Bruce

Hi Bruce.

Uploading pre-compiled code isn't allowed I think. You'll have to compile at your end.

Download the .cs file to your desktop or anywhere on your hard disk. Quit NinjaTrader if it's open. Now copy or move the .cs file to your NinjaTrader data folder (should typicall be inside your "Documents" and named "NinjaTrader 8"). Documents -> NinjaTrader 8 -> bin -> Custom -> Indicators. Drop the .cs file here in Indicators and restart NT.

Then compile. From Control Centre -> New -> NinjaScript Editor -> then press F5 or click the compile button.

Alternatively, just copy the code from the post above, then in NinjaScript Editor start a new indicator wizard pressing next until you reach "Generate". It'll create a new indicator - don't save it yet. Select all and delete the dummy code, and paste the code from the forum and then compile.

Awesome!! Thank you so much - that worked fine. I really appreciate your help.

Hi again,

Is converting these something doable for a non techie guy like me? Is there some online resource I could go to to teach myself?

I have another ToS script here that I'd really like for NT8:- V01.08.2012 Projection Pivots. Maybe there is a conversion somewhere though. If I can't find a conversion I'd be willing to give it a try....

If still looking, here's a quick conversion.

Samir Thank You!

This is the best conversion I have seen to date of the great ThinkScript info/data boxes to NinjaTrader NT8.

And a nice tight, readable info/rich presentation of volume information in in one panel.

Well Done.

Hi!

I would post a few screen shots of what you are looking (final screen views of this pivots Indicator).

There is a good chance it has already been coded and if we recognized it can help you find the existing indicator file.
