I want a strategy to only trade certain times of day. I've read through the relevant part of the manual, but I'm pretty sure I don't have the code right for only trading between say 17h and 8h, but this is what I have:

Code:
if(hour() >= 17 && hour() <=8){
   	if(crossUnder(Signal,-Threshold)) 
		reverseLong(1); 
	   else if(crossOver(Signal,Threshold)) 
		reverseShort(1);


Could someone help me get this correct?

Many thanks!
