Description
  • I'm using MC .NET SE v9.1 build 12061.
  • I have a couple of indicators that use ChartPoint2Point to draw towards the right edge of the chart. They worked great for many releases until build 12061.
  • Note that I am using a Custom Draw indicator and the Environment.RightScreenTime system variable.
  • ChartPoint2Point returns strange values for any chart that does NOT use a time-based scale. That is, volume bars or tick bars (haven't tried others). The values start at the right edge of the window (correct value) and then slowly drift left with each tick until they reach the bar/time where the indicator was initialized. Then ChartPoint2Point always returns the X coordinate of that bar as it moves left (when new bars are drawn).
  • Please see attached example indicator that illustrates the issue with debug output.

Sample output from today:
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 1036
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 1028
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 1012
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 1004
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 996
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 988
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 988
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 964
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 964
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 948
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 940
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 940
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 932
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 932
RightScreenTime = 12/7/2015 11:20:21 AM, rightEdge.X = 932
RightScreenTime = 12/7/2015 11:20:22 AM, rightEdge.X = 924
RightScreenTime = 12/7/2015 11:20:22 AM, rightEdge.X = 924
RightScreenTime = 12/7/2015 11:20:22 AM, rightEdge.X = 924

Steps to reproduce this issue
  1. Compile attached indicator and attach to a chart with volume based bars or tick based bars (not time bars).
  2. Notice that for volume based charts, the right edge X value starts at the right edge of the window and slowly moves left (lower value) even though there is no new bar (RightScreenTime remains the same). It eventually settles at the X coordinate of the latest bar on the chart. When a new bar arrives, the right edge X value again moves left and stays with the prior bar.
  3. For time-based charts, the right edge X value remains constant regardless of RightScreenTime or new bars.

There's an item that says fixed "future bar time stamps not correct" or something like that. That "fix" is most likely what caused this to break. In case anyone is reading this.
