Creating Custom Bar Type

[ballboy11]

Are there instructions to understand how to create a custom bar type. I have a theory that I want to create my own bar type. I want to use the 1 minute close price and 1 minute open price, but depending on my logic I want to draw it if it passes certain criteria

Can I get a indicator value withing a custom bar type. I would like to get an indicator value in order to change the bar.

Hello ballboy11,

Advanced ideas and code generally don't have tutorials but expect you to be at the level of understanding to use the existing scripts as examples.

There is the Minute bar type in the @MinuteBarsType.cs script and the UniRenko script on the forums.

Unfortunately, no. It is not possible to pass BarsRequests to an indicator as an input series.

A follow on question relates to incoming data. If that is Ticks, then each OnDataPoint seems to represent ONE Tick, which NT can then aggregate into whatever is needed (ie. 100 Ticks per bar or seconds bars etc.). Can I safely assume that if the raw data is ticks, that each datapoint is exactly one tick (where Open = High = Low = Close .. )?

If my raw data stream is BasePeriod.Minute, do I get 1 Minute Bars one at a time (completed 1 minute bars) and no updates within the minute? In other words, the data I get is not smaller than a complete 1 minute bar and hence I don't get data in between. Every bar I get is also closed .. which means I would not need to ever call UpdateBar in OnDataPoint if I want to create a 1 Minute Chart .. correct?

Thanks much for any help

My original question appeared twice, so I thought I would delete ONE of them, but now BOTH are gone

Can I UNDELETE it ?

Basically I was looking for more in depth tutorials or documentation about how to write Custom BarTypes which would explain when each of the methods are needed and what each of the methods cause to happen or not happen. I was looking at code examples from the existing BarTypes and I can understand the core idea what the methods do but I can't figure out what I would need to overwrite in my case ..

So basically I am looking for a pointer to any walk-though or educational doc that explains "Custom BarTypes for Dummies" like me

(PS: sorry for the repeats of my posts .. not sure how to send exactly one comment without duplicting everything else .. haven't been here for nearly 10 years)

Hello Kermit,

I'm not aware of anything like this that exists.

There is a trader that wrote his own book. I believe it was called ninjascript programmer's launch pad.

Below is a public link to a google search for this.
