Putting indicator thread to sleep

[grose]

Hi,

I have indicator code that writes out bar data to a file on bar close -- I configure the indicator to update on bar close only, so it would appear to be simple. However, I noticed in the time stamp in the data file that the bar close event one-minute bars sometimes would orruce at 58 or 59 seconds of the current as opposed to the almost always 00 or 01 seconds of the new bar. To insure that I only write the bar data just after the next bar has started, I would want to have the indicator thread sleep say 1.2 second at a time if a check shows that we haven't quite crossed the minute boundary.

Would having the thread on which the indicator is being calculated sleep interrupt/interfere with processing in other areas of the NT application?

Thanks,

Gordon

Gordon,

Let me start off by providing a little more information on how NinjaTrader builds bars. A minute bar is actually not on a 60 second timer. It checks the timestamps of the incoming ticks. When the timestamp of an incoming tick crosses the boundary of the minute then NT knows that a bar has closed and starts building a new bar. So it is possible to have the last tick of a bar timestamped as 58, receive the next tick as 01 and that will close the prior bar without seeing a 59 or 00 timestamp.

You should not sleep the indicator thread itself because that will lock up the whole application.
