Ah....
When you run the exploration rt click a result then choose "Show actual trades"
This will suppress additional buy signals until a sell has been reached. An
alternative is to use Exrem() in your buy sell
<FONT face=Arial color=#0000ff

<FONT face=Arial color=#0000ff
size=2>buy=exrem(buy,sell);
<FONT face=Arial color=#0000ff
size=2>sell=exrem(sell,buy);
<FONT face=Arial color=#0000ff
size=2>
A
description for BarsSince and Exrem can be found in the help files under "AFL".
There is also a section on running explorations which you may find good
reading :)

Jayson

PMTo: amibroker@xxxxxxxxxxxxxxxSubject: [amibroker] Re:
Formula question for Ichimoku ChartJayson -
Thanks - Your third paragraph is exactly what I am looking to do.
"If you only want to verify that today's signal was not preceded by
another signal in the last X days then you might have a look at
Barsince(), where barssince(ref(buy,-1) > X number of days....."I
tried to write this and got nowhere. Can you please explain this barssince
more in detail. I have no real name for my signal I have (suchs as MACD,
etc..), instead just have it set up as follows in automatic analysis with
the indicator builder as :"Buy = Cover = Close>span1 AND tl>sl AND
DL>Close"If these three items are true, then a green up arrow shows
up. My problem is the green arrows are not a one time event, but continue to
show up each day in sequence if the three are true. I want to find a way
to say "if this is the FIRST DAY for the green arrow showing up, then that
stock will show up on my list of scans.I know I am probabaly making it
more complicated than it seems, but I am a newbie here. Thanks for your
patience.JMB--- In
