Charts randomly stop responding - as well as NT

[WHICKED]

In the past there was a 'maximum limit' of how many calculations an indicator could compute and then NT would stop responding. Is that still a limit in NT8?

Hello WHICKED,

I am not certain of any kind of maximum limit for indicators, do you have any information about the limit you are speaking about such as a previous post or information?

There are certain actions that cannot be done many times in a row, for example if a strategy tries to submit an order an excessive amount of times in one OnBarUpdate call that may produce a warning about user events.

all the behavior that I see is the indicator is functioning and processing then, after a random amount of time or calculations the chart freezes, can not interact with the chart at all. can not close NT gracefully, no errors, no exceptions, nothing in the trace or log files. have to manually terminate NT to get it to close.

in the past there was a lock out of how many computations a indicator could perform and if it tried to execute a computation over a limit it would freeze the indicator and NT from computing further.

Hello WHICKED,

I am not aware of any type of max calculations, that does not sound familiar. If you have any information that was in the documentation or former post where that was relayed by support I could take a look into that. From your description it sounds like the indicator may have a programming problem. A freezing chart could indicate the indicator entered into an infinite loop or is doing something on the UI thread that caused a lockup. If one specific indicator is found to be the problem you would need to debug it to see what part of the logic relates to that outcome.
