[amibroker] Re: How to code "Take only first signal of the day"?

["quexos0" <quexos0@xxxxxxxxxxxx>]

thanks a lot man, i'll try it out.

What i meant was if there are multiple buy signals in the day, take 
only the first signal that appear. 
If I use Buy=exrem(buy,sell), the next buy signal for the day will 
still be taken if no position is held.
