P. S. Sorry for changing the happy condition
Close == HHV( close, 250 ); 
I am in a 23 months bearish market and I should wait for
years to meet such a condition.
Thank you for the example.

<DIV><FONT size=2>Thank you for explanation.</FONT></DIV>
<DIV><FONT size=2>As I see, in your example, buy-sell are pairs with a 5-day
