GetYByValue(price) returns large negative value

[tradesmart]

Within OnRender() I'm looping through a dictionary populated in OnMarketData() whose key values are prices. For each price I want to determine its Y-coordinate via chartScale.GetYByValueWpf(price) or chartScale.GetYByValue(price). Unfortunately, what I get consistently are large negative numbers such as -3260601 instead of the expected positive values.

The attached screenshot displays a chart whose bar #49 at 12:10 PM has 4 prices: 2055.75, 2056.00, 2056.25 and 2056.50. The output window shows the calculated Y values for each of those 4 prices, all of which make no sense to me.

This was working fine in NT7 but not in NT8.0.0.11 beta.

Inexplicably, if I connect to a live data feed, the Y values turn positive. Also, if I create a new indicator that simply displays Y values of O, H, L, C prices the problem does not occur. But, if I strip out all code from my original indicator unrelated to simply printing some sample Y values, the problem persists.

Hello tradesmart,

For further clarification, can you please provide a simplified sample script that is demonstrating the behavior that you are seeing? Additionally, please provide reproducible steps so I may test on my end as well.

I look forward to assisting further.

Hello tradesmart,

Please change your script's ScaleJustification property to NinjaTrader.Gui.Chart.ScaleJustification.Right (as this is where your price scale is located on the chart in the screenshot provided).

Ah, silly me. Somehow I overlooked that. Not sure why I set it to Overlay in the first place. Thanks for an easy fix. Wish all problems would be that simple to overcome.
