How do I change the Chart Scale at the beginning of a session?

Hello NT Team,

I need inside the strategy by clicking on the custom button to change the scale so that the beginning of the Chart was from the beginning of the current trading session and at the same time to return the normal Scale in Y. The strategy works on minutes.

Hello tanas.eduard,

Welcome to the NinjaTrader forums!

Unfortunately, the chart scales cannot be adjusted directly through code.

With the Price scale (the Y axis) it is possible to add an indicator that sets the MaxValue/MinValue in OnCalculateMinMax() dynamically. By making this the only chart object with autoscaling enabled, this would allow the indicator to control the scale and range.

Below is a link to a forum post that discusses.

Thank you for your answer.
But I have a slightly different problem.
We have added a button on the Chart, on which a screenshot is made. We need Chat aligned at the beginning of the trading session before pressing the button, because it can be shifted by the user at the moment of pressing.
By the link status of the Chart at the time of clicking on the button - https://snipboard.io/UslIVr.jpg

We want the X-axis Chart to be aligned to the beginning of the day and the Y-axis to be aligned to the appropriate scale. A screenshot of how we would like to align - https://snipboard.io/c20Wy4.jpg

We cant do it from OnCalculateMinMax because button fired event Click

Hello tanas.eduard,

The user would have to adjust this manually. As mentioned in post # 2, the chart scales cannot be adjusted directly through code.
