Saving a fixed price point while the trade is live

Hi guys,

I am stuck in amibroker with leaving a value fixed while the trade is on.

I have a moving average crossover point that I use as a sell zone. When a buy is triggered via two MA cross over that becomes my exit point. And when the low of a price crosses that line my trade exits.

Problem is as price moves about there would be multiple MA crossovers that invalidates the initial sell zone I marked.

I would like to know if there is a way to leave that value fixed while the trade is live.

Thank you.

Well, preferred close is a confirmed close.
So you use delay

Buy = Cross(C, MA(C,20));
Buy = Ref(Buy, -1);
Buyprice= Open;

Hi trash,

Thank you.
