RE: [amibroker] A Buy without a Sell?

Keith: great idea, thanks.

 

And thanks to the others who offered me the answer to perhaps the most basic of questions.

 

Someone said: "There are no dumb questions, only those that go unasked."

Ken --

I 've developed some fairly complex stop, limit, and stop/limit rules, and had some of the same experience you describe.

 

The way I handle it is to first calcuclate:  mybuy, mybuyprice, mysell, and mysellprice arrays and avoid the use of  the 'predefined' arrays, buy, buyprice, sell, and sellprice till the very end of my code.  Then the last few statements are:

buy = mybuy;   buyprice=mybuyprice, etc.

 

I believe that problems arise because buyprice is 'predefined' and "defines buying price array (this array is filled in with the default values according to the Automatic Analyser settings)"

 

Hope this helps.

Curious and basic:  I have a fairly good entry signal, and want to Buy on this signal.  I have no Sell signal, only want to follow a stop to take out the trade.  Initially a percentage stop and then turn it into a trailing stop.

 

But I can't get around the need for the Sell statement.  As I said, basic.

 

I have tried a BuyP = Valuewhen(Buy, Close,1);

Then Sell = 0.95 * BPrice < L; 

 

But while I see some places where this works, I see lots of other places where it did not.  Puzzling.

 

Anyone got a simple way to Buy on a signal and then ONLY sell on violation of a stop?

 

Thanks,

Ken
