Howdy All!

I'm building an expert advisor to work with Price Headley's acceleration band concept. Here is my current "Long Entry" code in the expert advisor:

C>Mov((H*(1+2*((((H-L)/((H+L)/2))*1000)*0.001))), 20, S )

AND
Ref(C,-1) > Ref(Mov((H*(1+2*((((H-L)/((H+L)/2))*1000)*0.001))), 20, S ),-1)

AND
C>Mov((H*(1+2*((((H-L)/((H+L)/2))*1000)*0.001))), 80, S )

This essentially generates an "enter" signal for every bar that closes above the acceleration band.

How do I limit the entry signals to only one at a time? I'd like to see one defined entry point, instead of a long stream of green buy arrows when I look at a chart.

Thanks in advance.

As *PP has suggested, a latch is necessary if you want only one entry signal for each exit signal. However, if all you want to do is identify the leading edge of a contiguous block of signals then a check for the current value being TRUE and the previous value being FALSE is all that's required.

Entry:=C>Mov((H*(1+2*((((H-L)/((H+L)/2))*1000)*0.001))),20,S)

AND Ref(C,-1)>Ref(Mov((H*(1+2*((((H-L)/((H+L)/2))*1000)*0.001))),20,S ),-1)

AND C>Mov((H*(1+2*((((H-L)/((H+L)/2))*1000)*0.001))),80,S);

Entry AND Alert(Entry=0,2);

The result line could also be written as:

Entry AND Ref(Entry,-1)=FALSE;

I believe the following formulas should also help for this. I did not create these formulas but figured I'd post them here to help out:

bc:=Ref(C,1)>C;{Replace with your Buy Condition}
