RemoveDrawObject not working in real time
Hi. When I use the RemoveDrawObject function to remove a specific drawing (the tag value is definitely unique -- it's generated using the current bar value plus a static text string), it doesn't work in real time (i.e., if I refresh the indicator the drawings that should have been deleted do disappear).
The indicator updates on every tick. The drawings are placed on the chart if a certain set of conditions are met, and once drawn on the chart a flag is set to true to note that the drawing exists. A separate variable continues to track whether or not the conditions still apply with each incoming tick.
On the first tick of the next bar (before the condition flag and drawing existence flags are reset for the new bar), there is a check of the condition flag and the drawing existence flag. If the conditions were not met on the last tick of the previous bar and the flag for the existence of a drawing is true, then the RemoveDrawObject() function is called for that specific tag ID (e.g., RemoveDrawObject("entryTag")). I added a Print to confirm that I'm reaching the conditional code block which contains the remove function.
Is there something obvious that I might be doing wrong, or are you aware of any bugs with this function? Again, when I refresh the indicator, objects are correctly removed.

This method is behaving as expected. I can't see at first glance what you may be doing wrong but there must be a logic flaw somewhere.
See my test indicator that demonstrates functionality in real-time. Run it on a 10 second chart to see. Import via File > Utilities > Import.
