[amibroker] problem with scaling out coading help needed.

["asitasu" <asitasu@xxxxxxxxxxx>]

dear all,

i am trying to test intraday trading system with simple break out entry rule.
but want to exit in steps as follow. 

entry rule : h > hhv of till 13.30 pm.
stop loss : (at time of entry) previous 3 bar low.
exit 1 : if price moves by 2 times atr(14) value than trail first
exit with high - atr(14) for 50 % of positions.
exit 2 : if exit 1 is true, than trail remaining position by
privious 3 bar low OR stop loss value which ever is high.
exit 3 : if market near closing time (ie 15.25 pm)

note atr(14) value for this purpose is value at time 13.30.(ie stationary
figure).

following is afl. it works ok as far as entry & stop loss is concern.
but not following scalin out code while i backtested on some intraday data. can some one help
in correcting my mistake.

help is highly appriciated.

asit.
