<SPAN
class=660034505-14122003>Ed, I'd suggest thinking through what you intend ExRem
to do for you. All it does is remove duplicate signals in the same direction,
which the backtester does automatically anyway. Typically it's only needed when
you want to plot your own buy/sell arrows in an indicator.
<SPAN

<SPAN
class=660034505-14122003>In any case, "duplicate" signals means ones without a
signal in the opposite direction between them, like two buys in a row without a
sell in between. That's why it takes two parameters -- it's about the
relationship between the signals in the two passed arrays.
<SPAN

<SPAN
class=660034505-14122003>That's why Sell has to be defined in the code you sent.
For useful results, not just defined, as in set to zero, but set to something
that alternates in a meaningful way with Buy. If Sell is always zero, once a Buy
happens, there won't ever be a Sell to alternate with, and your output will
contain only that one first Buy.

<SPAN
class=660034505-14122003>What was the original problem you were trying to solve
with ExRem? Were you plotting shapes or running a backtest? How were you
thinking you'd exit your buys?

>You
just need to define the sell condition, otherwise exrem is open endedand
undefineableYou could try using something that is impossible (normally)
like Sell = C<0;//close < zeroCheers,Graham<A
