[amibroker] Re: Limiting action to only once per bar

["gariki" <chetan.gariki@xxxxxxxxx>]

Hello Pebs,

What seemed to have worked for me is to change the intraday bar settings to use the time stamp for end of bar to represent it. That took care of multiple signals that keep coming until the next bar starts. Try it; it might solve your problem because you now dont need static variables (which stay in memory until you close your AB session; read from another post..).

Setting to change: 
Tools -> Preferences -> Intraday, then set the timestamp display to START or END time of interval.


Regards

When the number changes for a new bar, i want to run a piece of code, let's say a messagebox, or a little external program, but what is happening is once the new bar comes and the number of contracts changes this code keeps on executing 100's of times till the next bar arrives. I have tried setting a boolean variable but no success. I specifically dont want to use the alert function as i am already using it for something else on that bar.
