Buy High sell Low. Why not? :-)

The thing you are missing in the below is you have FORGOTTEN to use the
subscript in your loop, thus you are setting the ENTIRE ARRAY to True. The
last line of your loop should look like this and it will do what you are
expecting.

 

            {

            Buy[i] = H[i];

}

 

Actually, this is technically incorrect because, as Fred said, Buy is a
light switch, either 0 or 1. This sets Buy to the High. However it still
works because Amibroker treats ANY NON-ZERO Number as true, even a negative
one.

 

PS: I hope you are taking Fred's advice about not buying at the high ;-)

Hi,

Still trying to figure out working with Arrays, and it's apparent there is
something I am not getting.

My understanding of the following is: If in the i bar the cross of the MACD
was true, then Buy at the High. However, Amibroker is buying in several
circumstances (including when the condition is true).

Can somebody smarter than me please translate the following formula into
English so I can finally get it?

Thanks a lot again,

Jerry

 

 

Reason= Cross( MACD(12,26), Signal(9) );

for( i = 0; i < BarCount; i++ ) 

{

if (Reason[i] == True)

            {

            Buy = H;

}

}
