Hello AnkaS,

Thank you for your post.

As IBar was not documented in NinjaTrader 7 can you detail what you used it for and I can provide the equivalent in NinjaTrader 8?

I came here wanting to ask the same question. Let me give you an example of how I used IBar in NT7, hoping that you can advise me on how to transition my code to NT8:

Case 1 - Get an absolute bar by index

        var bar = Bars.Get(i);  // Get the i-th bar

Case 2 - Bar Math

        public static double Height(IBar bar)
        {
            return bar.High - bar.Low;
        }

        public static double Top(IBar bar)
        {
            return Math.Max(bar.Open, bar.Close);
        }

        public static double Bottom(IBar bar)
        {
            return Math.Min(bar.Open, bar.Close);
        }

It looks like you've removed Bars.Get(int) from NT8, so I'll have to change my Bar Math functions to take an index and a Bars object, e.g.:

        public static double Bottom(Bars b, int i)
        {
            return Math.Min(b.GetOpen(i), b.GetClose(i));
        }

It's not the end of the world, but it's certainly not as elegant as before.

Is there a better way? Please advise.

PS. Overall, I love the changes in NT8

Hello xsgex,

Thank you for your post.

The means in which you are handling this would make sense in context to what you did in NinjaTrader 7. I do no see a better way to achieve this.

Please let me know if you have any questions.

finally, what is the equivalent of IBar object and how to get in NT8?

Hello TazoTodua,

Thank you for your post.

IBar was undocumented in NinjaTrader 7, this means that if it's equivalent is in NinjaTrader 8 we would need to know what you use IBar for to then provide the desired operation in NinjaTrader 8.

I look forward to your response.
