[amibroker] How do I reference the last condition

[James <jamesmemphis@xxxxxxxxx>]

How do I reference only the last condition? In this case, say I want to buy when price crosses above the last pivot high or below the last pivot low. I define pivot high as:

 

Phigh = ( H > Ref (H, 1) AND H > Ref (H, -1) );

 

I want to buy if price crosses the last occurence of this and not an occurence 20 bars ago that could be at a lower price. So Phigh is only the last Phigh. Hope this makes sense.

 

Thanks in advance,

James
