RE: [amibroker] How to neglect the short signal before the sell signal of a long trade ?

You're welcome.  Learning how to use a loop to manipulate the AB variables
is useful knowledge because it's how you implement more advanced trade
management strategies like scaling in, scaling out, breakeven stops, etc.
The help file has some good examples.

Dbw, thanks a lot. The use of loop here is truely inspirational, I will test
and learn.

Here's one way to remove buy and sell signals while in the opposite trade,
use a loop after your exrem() statements:

bInBuyTrade = Buy[0];

bInShortTrade = Short[0];

for(i=1; i<BarCount; i++) {

       bInBuyTrade[i] = bInBuyTrade[i-1];

       bInShortTrade[i] = bInShortTrade[i-1];

       if(Short[i] AND bInBuyTrade[i])

              Short[i] = 0;

       if(Buy[i] AND bInShortTrade[i])

              Buy[i] = 0;

       if(Buy[i])

              bInBuyTrade[i] = 1;

       if(Sell[i])

              bInBuyTrade[i] = 0;

       if(Short[i])

              bInShortTrade[i] = 1;

       if(Cover[i])

              bInShortTrade[i] = 0;

}

Note: the above code is untested, but hopefully you get the idea.

Regards,

David

Subject: [amibroker] How to neglect the short signal before the sell signal
of a long trade ?

Hi, I am try to code a futures system . Understanding that to delete 
the multiple signals between the buy and sell point, we can use 

buy=exrem(buy,sell);
sell=exrem(sell,buy);

similarly,

short=exrem(short,cover);
cover=exrem(cover,short);

But I need more than that: I hope to delete the short signals before 
the sell signal of a Long trade is triggered, also , I hope to delete 
the Buy signal before the cover signal of a Short trades are triggered. 
How to implement this in AFL ? Thanks for any help
