I updated from version 2914 to 2939 and noticed a weird behavior with the scroll that did not exist in my previous version. When I scroll in on a chart (with either mouse wheel or hotkeys), it will trigger an infinite zoom in, it seems to be caused by the "Set X & Y Constant Relationship" setting combined with studies plotted on the chart. How I was able to reproduce it: 1) Open a new blank historical or intraday chart 2) Add a built-in study such as "Pivot Points-Daily" or "Moving average - simple" 3) Right click the Y-axis scale and enable "Set X & Y Constant Relationship". 4) Zoom in a bit 5) Try to zoom out - it will trigger an infinite zoom in and cause the candle body to cover the screen The only way to get out of that state is to either disable "Set X & Y Constant Relationship" or remove the study from the chart, but I don't want to disable that setting since I use it quite a lot. Hopefully you will be able to reproduce and fix this issue. |

Never used x&y constant relationship. Gave it a go and can repro what you see. Easiest is to move the chart so only 1 candle is on left. Then use mouse wheel to scroll (once might be enough) and the candle spacing goes very large. From 14E to 1905E. You can get your chart back my using Interactive Scale Range and dragging the scale to get prices closer together. |

This will be resolved in the next release. It was rather complex. It would not surprise us, if there were issues in the past. Which will be resolved in the next release coming out now. It is a subtle problem, involving the precision between four byte and eight point floating-point values. As we convert to 8 byte floating-point values in the program, there was a very slight comparison problem that was getting significantly magnified, when there was a calculation of the number of bars needed in the current view based on this type of scaling and the changes to it. Effectively there was no change in the number of bars but a different spacing was getting applied. Sometimes bar spacing can change, but does not change the number of the bars in the chart. Now the number of bars in the chart actually has to be determined to be changed, with this type of scaling before a new calculation for bar spacing is applied.
