I think this is where Heitor's suggested use of Alert() would be most helpful - to extend the flag
signal by one bar. Once the "Flag" variable has been created you can modify it as per the extra line
inserted in the code I originally suggested. This extra line of code simply modifies the first
"Flag" definition by adding one bar to the trailing edge.
FlagSet:=Cross(RSI(14),70);
FlagReset:=Hour()<Ref(Hour(),-1);
Init:=Cum(FlagSet+FlagReset>-1)=1;
Flag:=BarsSince(Init+FlagSet)<BarsSince(Init+FlagReset);
Flag:=Alert(Flag,2);
Flag;
You could modify the variable by using a line such as the following , but I'd not recommend it.
Using an indicator that requires past data to extend a signal forward is not a good idea, and this
is because it introduces another invalid bar into the formula result. Alert uses the current bar
only, so doesn't create an additional invalid bar.
Flag:=Flag OR Ref(Flag,-1);
Kind regards
