[amibroker] Re: Help needed - 20 period low

Tomasz,
I have a slight disagreement with your code.
Your barssincelow can not be greater than 19.
But, the distance from L==LLV(L,20) may be greater.
If KK question was for 24 periods ago, instead of 4 periods ago, then 
your code would give no solution.
My proposal is
 Cond=L==LLV(L,20);
Solution=Cond AND Ref(BarsSince(Cond),-1)>3);
