Subject: [amibroker] Elementary AFL?

I could use some help with what must be a most simple AFL.  My simple plan
is (with interday data) to:



1.         Buy on buy conditions.

2.         Not buy again if already long

3.         Sell on sell conditions

4.         When sold (step 3), reset everything so we can do 1-3 again on
future bars



It seemed to me that



Bought = flip (Buy, sell);



was a good way to go, but I can't make it work.  On the one hand, seems like
flip(buy, sell) has to go AFTER the buy and sell statements.  On the other
hand, you can't reference bought (line 3 below) until it's defined.   I
guess I could use applystop to do this, but I prefer the flexibility of
having my own exit code.



Can anyone help me do this?



Buy = conditions;

//Bought = flip(Buy, sell);  /Here?

Buy = buy and !Bought;

Sell = conditions;

Sell = sell and bought;

//Bought = flip(Buy, sell);  /Or here?



Thanks in advance.
