HOLDTILL()
<BLOCKQUOTE
>
I hope that the following will make things more
clear.
Suppose that I want to hold the Close value, when
macd() crossed its signal, until the moment
stochd()
crosses 70 line.
The cross(macd(),signal()) is true at A and
B.
Which value will be holded until point C, where
cross(70,stochd()) is true?

<SPAN

<SPAN
class=510131619-02122001>And I understand Flip()exactly as it is in reference
and in your examples. This means I understand Flip() will be True till the
second condition will be triggered. So I understand that since Flip() has
started to be True nothing else could change it into False then the second
condition - starting this moment Flip() does not care about the first condition
at all.
