The issue is when the scale range for the chart is set to a Constant Range. This issue only occurs when there is a movement in the market which causes a bar to take up the entire scale range of the chart. An example would be a large movement up where the range of the bar exceeds the amount set for the constant scale range. Upon trying to re-center the scale range, the price is still cut off because the range of the bar exceeds the constant range. Here is a method to reproduce it with a market replay. 1. The symbol is CLN22-NYMEX or CLN22_FUT_CME for the Teton service. 2. Apply a numbers bars study to the chart and change the bar period to 20-1 pnf. The issue is not unique to a specific bar period but that is the one we were using. There are no other studies on the chart. 3. The scale range is set to Constant Range with a range of 0.57. The Constant Range Scale Mode is set to Keep The Last Bar Within View with a setting of 2 ticks from the edge. All other scale range settings are default. 4. Using New York time, replay the market on the date 2022-06-13 at around 11:25 AM. The market makes a large movement higher around this time where the price exceeds the range of the chart. This is happening until the chart creates a new bar, at that point the issue is no longer there. If you let the replay run for a few minutes you will see another example where the market moves up and the price is cut off at the top. |
