problem with AFL code for Amibroker

hi all,
I have a problem with AFL code for Amibroker:
I made a buy signal: Buy=Cross(MACD(8,17),Signal(8,17,9))
I need to make a profit stop at 20% above Buy and 10% below Buy,
Please help me to write AFL code for this.
i will use it in back testing and my custom indicator.

thank you in advance for your help.

In Automatic analysis window on Stops tab use profit target and sl fileds to specify ur criteria. If u need to plot your criteria, some guidelines - Use valuewhen() function to get the rate at which ur buy signal triggred. But you have to remove redundant signals with exrem() function. May be i can help u later, sorry, now not enough time.

hi joy.edakad,
thank's for your quick reply, please send AFL code for this when you have time, I will wait.
