IsFirstTickOfBar called 3 times in Renko Bars

[sidlercom80]

Hi, why is the print statement called 3 times for renko bars and "IsFirstTickOfBar" instead of only 1 time? It's a bug?

Hello sidlercom80,

Thank you for your post.

Based on your screenshot, the three different prints have different values for CurrentBars[0]. Based on your condition, I would expect the script to print on the first tick of each new bar that is formed. If you right-click your chart and select "Show Data Box" and then right-click the data box and ensure "Show Bar Indexes" is checked, you may hover your mouse cursor and compare the bar index numbers with the numbers printed to the NinjaScript Output window.

Please provide more details about what you are trying to achieve if this is not the behavior you expected and I would be glad to assist you further.

I believe this is expected behavior with NinjaTrader Renko bars based on the characteristics of redrawing the finished bar.

I would imagine a work around is to deal with the 1st or 3rd call based on either a bool or a counter.
