  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,

  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
