Hi Graham,
Thanks again for your reply.
May be I have confused you, there is no second signal. Once the x
condition is met, a signal is created. The signal remains valid until
a buy or a y condition is met. When the signal is valid, a buy happen
when today price hit yesterday's high. Hope this is clearer. The
problem I have is once I use var1=valuewhen(x,h), the h value is
always remain even though the next bar cud be a lower H or higher H.
I am still not familiar with AFL enough.
Thanks
KK
