Re: [amibroker] Event Occurrence Check

Depending on what you want to do there are a number of ways to go.  To find the nth time that x is true you can use valuewhen() and adjust the 3rd parameter.  You can also use plotshapes() to place a shape at the bar where x is true or simply use plot() and change the color of the bar.  And probably a few more options.  It all depends what you want to do once you know when x is true.

Hi Bill,

Many thanks.

The check you have suggested is for an event that is occuring/occured
at this instant. Do you have any suggestion if I want to check if such
an event has occurred in the past - without having to specificy the
number of bars.

Has ADX() crossed over 40 ?

Would this be too unspecific for programming?

Regards

Ray
