Base Camp Trading doesn't currently offer a UniRenko bar type, but you can find several different variations of UniRenko bars in the NinjaTrader Ecosystem. The NinjaTrader Ecosystem is a library of tools for use by NinjaTrader users. You can reach it via this link https://ninjatraderecosystem.com/ , then search for UniRenko. (For example, click for NT7, or NT8, and UnirRenkoPrice for NT8 - use at your own risk).
Remember that a different UniRenko bar type is required for version 7 versus version 8. You can also find other NT indicators that could be useful, such as the Ichimoku cloud indicator or the bar closes indicator. The indicators that Base Camp Trading provides are proprietary. Most of our proprietary indicators are available for NinjaTrader and are available in the Base Camp Trading store.
